Solid lubricant powder and powder will bush mixed, forming substrate material, heating, sintering bush made, and cooperate together to the trunnion called the sintering bearing. This bearing in the process of friction to the friction surface a continuous supply of solid lubricant.
Bush substrate material usually use metal, lubricant is layered with solid lubricant. Note that the matrix materials and lubricant should have the enough strength. Can join the increase of invasive additives, such as Ca-Si alloy can increase iron and graphite sintering of mutual invasive. The practice shows that Cu-Ag-MoS2 and Fe-Pb-MoS2 sintering bearing has good performance.
The strength of the sintering bearing and lubricant is proportional to the mass fraction, comprehensive consideration of the bearings strength and tribological properties, the industrial production of mass fraction of lubricant limited under 10%.
