【Abstract】 This paper observes and analyses the structural transformation of electroless Ni Co P coating heat treated under different temperatures with H 800 transmission electron microscope. The results show that the amonphous crystalline transition of the coating will take place when the heat treatment temperature exceeds 350?℃.Compared with the crystallization process of Ni P coating, it can be concluded that the presence of the third element of cobalt improves the heat stability and raises the crystallization temperature of electroless coating.更多还原
