摘要: 探讨了添加剂Ce~(4+)对Co-P-PTFE复合镀层的影响,结果表明,添加剂Ce~(4+)可降低Co-P-PTFE复合镀层在3%NaCl溶液中的腐蚀电流,提高其耐蚀性。同时使复合镀层微观结构发生变化,择优取向由(100)面转变为(110)面,且晶粒尺寸降低.

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.
