One of DML-V03BD surfacing systems are developed by our company have complete independent intellectual property rights metal surface modification equipment, the welding process is to improve the metal surface abrasion resistance, corrosion resistance and impact resistance and other properties of the effective technical methods . DML-V03BD works: high temperature plasma powder surfacing is a plasma arc as a heat source, the application of plasma arc generated by the alloy powder and the substrate surface is rapidly heated and melted together, mixing, diffusion, coagulation, plasma beam after leaving the self-excited cooled to form a layer of high-performance alloy layer in order to achieve enhanced with the surfacing process hardened parts of the surface, due to the arc plasma arc has a high temperature, the heat transfer rate, good stability, penetration controllable by adjusting related heap welding parameters, the thickness of the cladding layer, width, hardness freely adjusted within a certain range. After the formation of plasma powder surfacing between the base material and surfacing materials integration interface, high bonding strength; surfacing dense, corrosion and wear resistance; dilution matrix material and surfacing material is reduced, small changes in material properties; As the use of the powder can improve the selectivity of the alloy cladding material is designed, in particular, smooth surfacing refractory materials to improve wear resistance of the workpiece, high temperature corrosion resistance. DML-V03BD technical advantages: 1, surfacing alloy cladding layer and the base takes the shape of the workpiece metallurgical bonding, combined with high strength; 2, surfacing cladding speed, low dilution rate; plasma arc welding dilution rate can be controlled at 5% a 10% or less. 3, dense surfacing layer, forming beautiful; welding process is easy to realize mechanization and automation; 4, surface rust on metal parts and oil are without complicated pre-treatment process, direct plasma welding; 5, and other plasma simple structure compared spray equipment, energy-saving and easy to operate, easy to maintain maintenance; 6, plasma arc, high temperature, energy concentration, good stability, residual stress in the workpiece and cause little deformation. 7, good controllability. By changing the power to change the structure size gas type, flow and nozzle to regulate plasma arc atmosphere, temperature and other parameters of the arc, in order to achieve efficient automated production, improve labor productivity. 8, using a wide range of materials. Restrictions surfacing alloy powder as cladding material, without casting, rolling, drawing and other processing can be configured to different components of the alloy powders based on different performance requirements, especially for those difficult but easy milling silk hard resistance run-gold, to obtain the desired performance surfacing layer.
