PROPERTIES OF ELECTROLESS Ni- P ALLOY PLATING ON PARTS OF CAST IRON
铸铁件的Ni-P合金化学镀层性能研究

Taking QT600-3 and HT200 as object ,the influence of P content,morphology,and post-treatment on anti-corrosion behavior of Ni-P alloy coating;the influence of heat treatment on surface hardness of Ni-P alloy coating;and the influence of activation on adhesive strength of Ni-P alloy coating are analyzed on the base of experiments.Testing results show that the Ni-P alloy coating possesses well physical and chemcial performance.
