摘要
用化学沉积法在ＰＴＣＲ陶瓷上制作镍电极可形成良好的欧姆接触，且成本较低。通过实验，优选出了合适的镀液成分、浓度及施镀条件。用扫描电镜分析了镍层的结构和成分，探讨了镀层的生长机理，并描述了核生长机理的模型。
By chemical deposition process,nickel electrode on PTCR ceramics of
ohmic contact can be acquired at low cost.Optimiaed composition and concentration of plating
solution,plating conditions are obtained through experiment. The compositions and structure of
nickel plating are analyzed through SEM.The growth mechanism of deposited nickel is
investigated and nucleus growth model presented.(4 refs )
