论文已在中国上海举行的2013年CIMAC大会上发表。论文的版权归CIMAC所有。Typical plain bearing alloy, Sn-Sb-Cu alloy is being overlaid on the carbon steel backing metal by either casting or welding method. Overlay welding type bearing is a competitive alternative to casting type in terms of higher bond strength and lower cost. Surface protrusion phenomena at the running surface of welding type bearing were occasionally observed after engine operation. Occurrence of protrusion phenomena were simulated as a function of dehydrogenizing treatment, preheating before welding and postheating after welding. It was found that the protrusion of weld overlaid bearing surface was closely related to diffusion and build-up of hydrogen from the backing steel.
