AI Technical Summary
Existing bearing manufacturing processes are insufficient to meet the performance requirements of high-precision, high-load, and high-speed mechanical equipment. Traditional methods suffer from problems such as low interfacial bonding strength, microstructure segregation, and high processing difficulty.
The process employs volatile paste-like alloy powder and CMT secondary metallurgy, where the welding wire reacts in situ with the alloy powder coating on the substrate surface at high temperature to form a tin-based Babbitt alloy brazing coating, resulting in high bonding strength and a fine and uniform microstructure.
It significantly improves the strength, wear resistance, and fatigue resistance of bearing bushes, breaks through processing limitations, and meets the needs of modern industry for high-performance bearing bushes.
