In the oil exploration industry, as the drilling pump pressure continues to increase, the erosion failure problem of oil drilling steel drill bits is becoming more and more serious. The working conditions of the drill bits are becoming more and more complex and harsh, and higher and higher requirements are placed on the wear-resistant layer of the drill bit cladding. At present, the wear-resistant cladding layer for oil drilling tools PDC drill bits mainly relies on imported welding ropes. The carbide wear-resistant flexible welding rope products developed by Luoyang Golden Egret has very excellent corrosion resistance and wear resistance, and high impact resistance, and have been successfully used in this field. Luoyang Golden Egret tungsten carbide wear-resistant flexible welding rope is made by extruding and coating a mixture of nickel-based alloy powder and irregular cast tungsten carbide particles, spherical cast tungsten carbide particles, cemented carbide balls, diamond particles, etc. on the surface of the nickel core. The product uses nickel-based alloy as the bonding phase and tungsten carbide as the hard phase. The product performance characteristics are as follows:tungsten carbide wear-resistant flexible welding rope surfacing layer diagram Hard phase distribution: The hard phase is evenly distributed in the cladding layer, which makes the cladding layer have good corrosion resistance, wear resistance and impact resistance, and the performance reaches or even exceeds the standards of imported product

Electric separation technology is the key technology to remove non-metallic inclusions in powder. Its principle is to charge the powder particles through corona discharge phenomenon, and then use the difference in electrical properties between the metal powder and non-metallic inclusions to separate. Figure 6 is a schematic diagram of the principle of high voltage electrostatic separation. The electrostatic separation device is composed of two electrodes, the negative electrode is a thin metal wire, and the positive electrode is a large diameter metal drum which is grounded and has a certain speed. When the potential difference between the two stages reaches a certain value, corona discharge occurs between the two poles. After the metal powder containing non-metallic inclusion falls into the corona electric field formed by the feeder, it meets the electrons and negative ions flying to the positive electrode, making it carry the negative charge of the roller. Due to the high electrical conductivity of the metal powder, the obtained negative charge is released quickly after contact with the roller, and falls into the finished powder collection area from the front of the roller under the action of gravity and centrifugal force. The non-metallic inclusion is not easy to lose charge due to its low conductivity, and is adsorbed on the roller under the action of coulomb force and electrostatic adsorption, and is brushed down by the roller when it rotates to the rear wi

Vacuum induction melting gas atomization (VIGA process) Vacuum induction melting gas atomization method means that in vacuum environment, the coil induction heating principle is used to melt the charge, after reaching a certain temperature, the melting chamber and atomization chamber are filled with atomizing gas, and then the molten steel is poured into the tunic, and the metal liquid flow is formed through the nozzle into the atomization chamber [18], and then the high-pressure inert gas is used as the atomizing medium to break the continuous metal liquid flow. It quickly solidifies into fine particles, that is, metal powder. FIG. 1 shows the schematic diagram of aerosol vaporization principle.   Figure 2 shows the powder produced by vacuum induction melting gas atomization process. From the surface morphology, it can be seen that the particle size of the powder obtained by gas atomization method is dispersed, generally about a few microns to more than 100 microns, and the sphericity is preferred, but there are satellite powder and adhesion powder.

Case study of thermal barrier coating（2）  It is believed that the peeling of the ceramic layer is not the sudden cracking at the interface, but the residual stress induced the cracking of the coating layer along the thickness direction. The residual stress in the thermal barrier coating mainly comes from three aspects: the thermal stress generated during the molten droplet cooling during the plasma spraying; the thermal stress caused by the thermal barrier coating; the high temperature growth stress of the bonding layer after the thermal cycle oxidation. For the first type of stress, it has been described above that using the preheated matrix and optimizing the spraying parameters can reduce the residual stress in the spraying process. For the latter two types of residual stress, the double ceramic layer structure can be solved. MaW et al. prepared La2CeO7 / 8 YSZ double-layer ceramic thermal barrier coating. Compared with La2CeO7 and 8 YSZ coatings alone, this design of double-layer ceramic coating effectively overcame the thermal expansion mismatch between La2CeO7 coating and binding layer, and its life was significantly higher than that of La2CeO7 and 8 YSZ coatings alone under high temperature cycle conditions. Similarly, Liu Z G et al. prepared the bilayer (La0.8Eu0.2) 2 Zr 2 O 7 / YSZ, peeling off parts of the coating after the thermal cycle test. And peeling area microscopic morphology a

Case study of thermal barrier coating    Thermal barrier coating (Thermal barrier coatings, TBCs) is a protective coating used in high temperature environment such as turbine blade, combustion chamber wall and tail nozzle of aero engine. Different from the traditional protective coating structure, the thermal barrier coating usually consists of a metal bonding layer and a layer of ceramic insulation layer, sometimes adding oxygen barrier layer, sealing layer and gradient layer to form a multi-layer structure or gradient structure. The structure diagram is shown in Figure 5. The bonding layer in the thermal barrier coating mainly plays the role of alleviating the mismatch of the thermal expansion coefficient between the ceramic layer and the matrix, and improving the physical compatibility between the two, while the main ceramic layer directly faces the external high temperature environment, which needs to have low thermal conductivity, high expansion coefficient and high thermal stability. At present, the most commonly used ceramic layer material is YSZ, but 1200℃ is the limit of the use of this material. When the temperature exceeds the limit temperature, ZrO 2 will be phase change, leading to a certain expansion of the coating, affecting the use of the coating. In recent years, new ceramic laye

In geology, mining, coal mining, subway shield and other industries, the workpieces are required to have excellent wear resistance and cutting performance simultaneously. While the traditional wear-resistant surfacing layer such as high chromium alloy can no longer meet the requirements of the workpieces on service life and cutting performance. Thus, adding tungsten carbide particles with high wear resistance and cutting properties into the surfacing layer has become one of the effective means to improve the wear resistance of the surfacing layer. Tungsten carbide grains from Luoyang Golden Egret Geotools consist of carbide alloy spherulite and carbide alloy particles, mainly with WC-Co and WC-Ni. 01 Product Performance

In today's industrial field, cemented carbide tools such as cutter, oil wells drilling bits, impact drilling bits, etc., are gradually replacing traditional tool materials with their excellent thermal, mechanical and chemical properties. The core raw material of this high-quality tool is tungsten carbide powder (WC powder), which is made by a special process of powder metallurgy. Compared with conventional tools, cemented carbide tools show significant advantages, including great hardness and strength, excellent red hardness, wear resistance, toughness, heat resistance and corrosion resistance. It is particularly striking that the hardness and wear resistance of cemented carbide tools can remain stable even at a high temperature of 500 ° C, while at 1000 ° C, its hardness is still quite high. These excellent properties are attributed to the unique properties of WC powder.

Luoyang Jinlu Carbide Tools Co., Ltd. participated in the GTF2024 Chengdu "two machines" exhibition to talk about the emerging trend and cutting-edge technology of "two machines"! Thermal spraying technology is a new technology for strengthening and protecting the surface of materials, and it is one of the most effective techniques for surface modification in the field of surface engineering. Thermal spraying refers to the method of heating the spray material inside or outside the spray gun to a plastic or softened state, and then spraying it on the surface of the pretreated substrate, basically keeping the state of non-melting to form a coating. Using different heat sources and spraying equipment, a series of coatings with various functions such as anticorrosion, wear resistance, wear reduction, high temperature resistance, oxidation resistance, heat insulation, insulation, conductivity and microwave radiation protection can be prepared. Thermal spraying technology can repair the old and waste in equipment maintenance, so that the scrapped parts "back to life"; It can also be strengthened and pre-protected in the manufacture of new products to "prolong life". It plays a large role in saving energy, saving materials, improving efficacy and reducing costs, especially suitable for China's national conditions, in line with our current economic policies, and is an important practical technology currently advocated by the state for energy con
