| Abstract: | According to its special working conditions,thrust bearing for turbocharger was made for the first time by powder metallurgy techniques.Constituents of the matrix material and its mutual effects were studied on condition that major technology parameters had been decided.Tribological behaviors were tested.Comprehensive checking data on saddle piece were analysed.Meanwhile,the performances of this kind of products were compared with those of similar products used internationally nowadays.The results showed that the tensile strength and the self lubricating performance of the material were better.So far,this kind of products has been commercially produced and wholesale applied,with satisfactory economic benefit. |
