Halnn launched BN-S20 for processing spraying parts
Thermal spray welding typically include nickel-based alloys, iron-based alloy and cobalt-based alloy spray powder, according to different alloy spray coating layer, spray welding hardness were applied to repair mechanical parts or to increase the metal surface properties; Spray coating thickness will be from 0.01mm to a few millimeters; Spraying coating/spray layer hardness generally≥HRC50; Part spray welding layer hardness≥HRC65; Machine machining cutting tool of spray coating layer and spray welding layer always is to limit hard surface later period processing technology problems. Compared with the sprayed coating, spray welding layer owns more significant advantage. However, due to the temperature up to 900 ℃ after matrix local heating in remelting process, it will have a greater thermal deformation.
BN-S20 is better suited for the materials with high impact load, high surface hardness ma, as well as part structural steel, nickel-chromium stainless steel, cast iron and other materials.
