Introduction: Spray welding first sprays self melting alloy to the surface of the part with flame, then heats the pre-heated self melting alloy powders up to 1000℃ with flame or sensing method, so that the powders melt and the particulates float to the surface. The formed borate and silicate disperse in the spray coating layer and bond the powders with the base. The resulting deposition is a condensed metal crystalline structure that forms a metallurgical bonding layer with the base of thickness about 0.05~0.1 mm. It possesses high bonding strength and great resistance to impact, wear and corrosion.
• Non-porosity • The spray layer is metallurgical bonding and has a larger heat-affected zone than being processed by laser • The hardness is usually between HRC 40-60 • Part of the spray coating layer has high resistance to wear • Spray coating layer has good resistance to corrosion
