Abstract

The effect of additive Ce4+ on the properties of composite coating of Co-P-PTFE was studied in this paper.The results show that additive Ce(4+) can change the structures and properties of Co-P-PTFE composite coating. First,the surface of the compoite coating becomes smooth and the microhardness of the composite coating increased.Secondly,additive Ce(4+) decreased the corrosion current lcorr of the composite coating in the solution of 3% NaCl and increased its property of anticorrosion.Finally additive Ce(4+) can affect preferred orientation and grain size of composite coating of Co-P-PTFE. Preferred orientation of the composite varies from(100)to(110)and the grain size decreased.
