The editor of Duomu Industry tells everyone that the powder surfacing machine is a metal surface modification equipment with completely independent intellectual property rights. It is an effective technical means to improve the wear resistance, corrosion resistance and impact resistance of metal surfaces.
The powder surfacing machine uses plasma arc as the heat source, and uses the high temperature generated by the plasma arc to quickly heat the alloy powder and the surface of the substrate to fuse, mix, diffuse, and solidify. After the ion beam leaves, it self-excitedly cools to form a high-performance alloy layer. Realize the strengthening and hardening of the surface of the part.
Because the plasma arc has the characteristics of high temperature, high heat transfer rate, high stability and good penetration depth controllability, by adjusting the corresponding surfacing welding parameters, the thickness, width and hardness of the surfacing layer can be adjusted freely within a certain range . The matrix material and the surfacing material form a fusion interface after plasma powder surfacing, which has a higher bonding strength; powder surfacing can improve the selectivity of alloy material design, especially for the smooth surfacing of refractory materials and improve the resistance of the workpiece Abrasion, high temperature stability and corrosion resistance. The powder surfacing machine has high productivity and beautiful appearance, and the surfacing process is easy to realize mechanization and automation.
Technical advantages of powder surfacing machine
The surfacing cladding alloy layer is metallurgically combined with the workpiece matrix, which has a high bonding strength;
The cladding speed of surfacing welding is fast and the dilution rate is low; the dilution rate of plasma arc surfacing welding can be controlled at 5%-10% or lower. The surfacing layer has dense structure and beautiful appearance, and the surfacing welding process is easy to realize mechanization and automation;
Without complicated pre-treatment process, plasma spray welding can be directly carried out on the surface of rusty and oily metal parts;
Compared with other plasma powder surfacing welding, this equipment has a simple structure and is easy for energy-saving operation and maintenance;
The plasma arc temperature is high, the energy is concentrated, the stability is good, and the residual stress and deformation of the workpiece are small. Can be well controlled. By changing the power, gas type, flow rate and nozzle structure size, the plasma arc gas adjustment, temperature adjustment and other parameters can be realized to realize high-efficiency automatic production and improve labor productivity.
Because the powder surfacing machine has the advantages of high arc column temperature and powder surfacing, the editor of Duomu Industrial believes that it can greatly simplify the surfacing process, especially the use of multiple alloy elements, and the performance can be obtained under the action of plasma arc Different hard surface effects. Moreover, the dilution rate is low, the binding force is strong, the work efficiency is high, the process is simple, and no special treatment is required.
