Plasma Hardfacing

Plasma Hardfacing: Plasma powder surfacing uses a plasma arc as a heat source. The alloy powder and the substrate surface are rapidly heated, melted, mixed, diffused, and solidified by applying the high temperature generated by the plasma arc. After the plasma beam leaves, it cools down and forms a high-performance alloy layer. Thus the surface of the part is strengthened and hardened.

Due to the plasma arc has a high arc temperature, high heat transfer rate, excellent stability, melt depth controllability. By adjusting the relevant surfacing parameters, the thickness, width, and hardness of the surfacing layer can be freely adjusted within a specific range. Plasma powder surfacing after the formation of a fusion interface between the base material and the surfacing material, the combination of high strength. Surfacing layer organization dense, corrosion resistance, and excellent wear resistance. The dilution of the base material and surfacing material is reduced, and the material properties change little. The use of powder as surfacing material can improve the selectivity of alloy design. In particular, the ability to smoothly surfacing refractory materials. Improve the wear resistance, high temperature resistance, and corrosion resistance of the workpiece. Plasma powder surfacing offers high productivity and aesthetically pleasing shapes and can easily mechanize and automate surfacing.

PTA HARDFACING MACHINE FOR PLATE

  • Plasma-transferred arc (PTA) welding is a thermal process for applying wear- and corrosion-resistant layers on surfaces of metallic materials. It is a versatile method of depositing high-quality metallurgically fused deposits on relatively low-cost surfaces. The PTA process is used in instances of extreme demands on wear resistance.
