Development of Lead Free Copper Based Alloy for Piston Pin Bushing Under Higher Load Engines

Tribological performances of CuSn10Bi3 alloy containing MoSi2 and ferrophosphorus under starved lubrication

“…However, under lubrication conditions, the holes can store more lubricating mediums to maintain good friction and wear properties [26]. Generally speaking, grain size and mechanical properties of the material in a steady-state conform to the Hall-Pitch relationship, that is, the smaller the grain size, the stronger the mechanical properties of the metal [11]. It can be seen in Figure 3 that the grain size of Material A: CuSn10Bi3 is the largest, and the edge of the grain boundary is sharper.…”

“…Relevant researches show that adding different nitrides, borides and silicides as particle reinforcement phase can effectively improve the tribological and mechanical properties of the alloy [11][12][13]. Intermetallic compound molybdenum disilicide (MoSi 2 ) has both performances of metal and ceramic.…”
