Application of Plasma Cladding Ni60A+35wc Wear-resistant Layer on Agricultural Machinery Knives(6)

       Technical advantages:
1. The surfacing alloy layer is metallurgically bonded with the workpiece matrix, and the bonding strength is high; 2. Fast surfacing cladding speed and low dilution rate; the dilution rate of plasma arc surfacing can be controlled at 5%-10% or lower. 3. The surfacing layer is dense in structure and beautiful in shape; 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 temperature is high, the energy is concentrated, and the stability is good, and the residual stress and deformation caused on the workpiece are small. 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
