The company operates plasma powder surfacing welding machine, quality assurance, welcome to consult and negotiate.
Working principle of DML-V03BD: Plasma powder surfacing uses plasma arc as the heat source. The high temperature generated by the plasma arc is used to rapidly heat the alloy powder and the surface of the substrate and melt, mix, diffuse, and solidify together. After the plasma beam leaves, it is self-excited and cooled to form A high-performance alloy layer, so as to realize the strengthening and hardening of the surface of the parts, because the plasma arc has high arc temperature, large heat transfer rate, good stability, and strong controllability of penetration. Welding parameters can be freely adjusted within a certain range of the thickness, width and hardness of the surfacing layer. After plasma powder surfacing, a fusion interface is formed between the base material and the surfacing material, with high bonding strength; the surfacing layer has a dense structure, good corrosion resistance and wear resistance; the dilution of the base material and the surfacing material is reduced, and the material characteristics change little; The use of powder as a surfacing material can improve the selectivity of alloy design, especially for smooth surfacing of refractory materials, and improve the wear resistance, high temperature resistance and corrosion resistance of the workpiece.
Technical advantages of DML-V03BD:
1、The surfacing cladding alloy layer is metallurgically bonded with the workpiece matrix, and the bonding strength is high;
2、The surfacing cladding speed is fast and the dilution rate is low; the dilution rate of plasma arc surfacing can be controlled at 5%-10%, or lower.
3、The surfacing layer has dense structure and beautiful appearance; the surfacing process is easy to realize mechanization and automation;
4、Plasma surfacing can be directly carried out on the surface of rusty and oily metal parts without complicated pre-treatment processes.
5、Compared with other plasma spray welding, the equipment is simple in structure, energy-saving, easy to operate, and easy to repair and maintain;
6、The plasma arc has high temperature, concentrated energy, good stability, and small residual stress and deformation caused on the workpiece.
7、Good controllability. The arc parameters such as the atmosphere and temperature of the plasma arc can be adjusted by changing the power, the type of gas, the flow rate, and the structural size of the nozzle, so as to realize efficient automatic production and improve labor productivity.
8、Wide range of materials used. As a deposited material, surfacing alloy powder is not restricted by casting, rolling, wire drawing and other processing techniques. It can be configured with different composition alloy powders according to different performance requirements. It is especially suitable for those hard to wire but easy to make powder. Grind the alloy to obtain the surfacing layer with the required properties.
