| 摘 要： | 一些特殊的工件在加工过程中,镀层易起皮、脱落,镀层与基体间有一过渡层可避免这一点,这通常可通过局部热处理加以解决;而传统的扩散退火热处理中,热量是从材料外部向其内部传递,整个材料都被加热,要实现镀层与基体的界面扩散,就会不可避免地造成纳米晶镀层的晶粒长大;而且如果只需对材料的某个局部加热,其效率显然较低.为此,对电沉积...

| Abstract: | Resistance spot welding tests were conducted for electrodeposited nanocrystalline Ni coating and carbon steel substrate.The feasibility to realize atomic diffusion at coating-substrate interface by using heat generated via contact resistance at the interface under electric current was investigated,and corresponding effect on the microstructure of the Ni coating was examined.The crystal structure of the nanocrystalline Ni coating before and after spot welding was analyzed by means of X-ray diffraction,and th... |
