Fe-Ni-P 合金镀层与几种材料配副在边界润滑下的摩擦学特性

The Tribological Characteristics of Fe-Ni-P Alloy Coating against Different Materials under Boundary Lubrication

研究了Ｆｅ－Ｎｉ－Ｐ合金镀层与４５＃钢、ＧＣｒ１５轴承钢、ＱＳｎ６．５－０．４磷锡青铜、１Ｃｒ１８Ｎｉ９Ｔｉ不锈钢、Ｃｒ镀层或Ｎｉ－Ｐ镀层分别组成摩擦副时在边界润滑下的摩擦磨损性能．结果表明：在给定的试验条件下，Ｆｅ－Ｎｉ－Ｐ合金镀层与１Ｃｒ１８Ｎｉ９Ｔｉ奥氏体不锈钢组成摩擦副对摩时容易产生粘着，磨损量和摩擦因数都比较高，而且配副材料的抗擦伤临界载荷也很低；以Ｆｅ－Ｎｉ－Ｐ合金镀层分别与其它５种材料对摩时的耐磨性都相当好，摩擦因数也都很低，尤以Ｆｅ－Ｎｉ－Ｐ合金镀层／青铜的耐磨性能最好，而ＧＣｒ１５轴承钢与Ｆｅ－Ｎｉ－Ｐ合金镀层组成摩擦副时的抗擦伤性能最佳，然而４５＃钢与Ｆｅ－Ｎｉ－Ｐ合金镀层组成摩擦副对摩时的抗擦伤临界载荷却很低；在一般情况下，用于与Ｆｅ－Ｎｉ－Ｐ合金镀层配副材料的硬度愈低，其在擦伤时对应的磨损体积损失的变化愈大．

The tribological characteristics of FeNiP alloy coating against 45# steel,GCr15 bearing steel,bronze,1Cr18Ni9Ti stainless steel,Cr coating and NiP coating were studied under the boundary lubrication.The results showed that FeNiP/1Cr18Ni9Ti is easy to produce adherence under the given conditions, the wear volume loss and friction factor are higher,the antiscratch critical load is very low; The antiwear properties of friction pairs composed of FeNiP alloy coating against other five materials respectively are all better,especialy,the antiwear property of FeNiP coating/bronze is the best.The antiscratch property of FeNiP coating/GCr15 bearing steel is optimal, but the antiscratch critical load of FeNiP coating/45# steel pairs is very low . The lower hardness of materials,the more variation of the wear volume loss on scoring.
