失稳

The results show that the grain sizes of nickel platings prepared under different electrodeposition time slightly fluctuate at 21 nm.

结果表明，不同电沉积时间下制得的镍镀层晶粒尺寸在21 nm小幅波动；随着电沉积时间的延长，纳米晶镍镀层的显微硬度存在先增大后缓慢降低的趋势，最大值为472 HV0.01，对应的电沉积时间为16 m in；纳米晶镍镀层的微观形貌为累积长大的胞状结构，电沉积时间为1~4 m in时，胞状结构表面密布着粒径为90 nm左右的二次纳米镍颗粒；本试验制得的纳米晶镍镀层失稳长大的起始温度为283.7℃，峰值温度为311.4℃。
