本文着重研究镍沉积层内应力的影响因素,如溶液种类、主盐浓度,槽液温度、电流密度、pH值、添加剂、沉积层厚度等。通过镍沉积层内应力影响因素的试验,寻找出瓦特槽的最佳工艺条件。本文还简略地叙述了测量内应力的方法,并通过对镍沉积层的结晶取向分析,对内应力形成的机理作了初初的探讨和解释。 This article focuses on the factors that affect the stress in nickel deposit, such as the type of solution, the concentration of main salt, bath temperature, current density, pH value, additive and thickness of deposit. Through the experiment of influencing factors of internal stress in nickel deposit, the optimum process conditions of watt cell were found out. This paper also briefly describes the method of measuring internal stress. Based on the crystal orientation analysis of nickel deposit, the mechanism of internal stress formation is discussed and explained at first.
