Investigation on Causes for Effects of Siliconization upon Wearability of Copper Alloy

Siliconized parts, which have been used by many works, are proved to be of good wear proof effect. Improvements in crystal structure, stacking fault energy, interfacial segregation of solute atom, metallographic structure, fracture toughness, and dynamic hardness, etc. are the causes for raising wearability of siliconized copper alloy parts.
