AN INVESTIAGTION ON MICROSTRUCTURE AND WEAR RESISTANCE OF Ni-WC SPRAYING LAYER WITH RE ADDED

本文通过在镍基自熔合金粉末中添加少量稀土 ,探讨稀土对 Ni-WC喷焊层组织和耐磨性的影响 .结果表明 ,适量地加入稀土可以改善喷焊层焊态组织 ,提高喷焊层硬度和耐磨性 ,而且 。

This paper presents a study on the effect of rare earths on the Ni WC spraying layer.It shows that the microstructure and wear resistance of the layer may be improved by adding appropriate quantity of rare earths to the spray coating.In this way,excellent processing properties can be obtained.
