摘　　要：用Nano IndenterⅡ纳米显微力学探针加载得到电沉积镍镀层的载荷-位移曲线,并对镍镀层中的残余应力进行了计算.结果表明:普通镀镍带中镀层存在残余拉应力,T处理使得镀层的残余拉应力减小,T处理镀镍带轧制后镀层拉应力变为压应力,再结晶处理也使得镀层的拉应力变为压应力,轧制后的再结晶镀镍带残余压应力变大.Residual stresses inelectrodeposited nickel enating were detemined from the p-h curves obtained by Nano Indenter Ⅱ mechanical properties microprobe, It is found that the residual stress in the general nickel coating was tensile, T-treatment decreased the residual stress, rolling made the residual stress in T-treated nickel coating converted from tensile to compressive, recrystallization-treatment also changed the sign of the residual stress, the compressive stress in recrystallization-treated nickel coating increased after rolling.
