选用快速镍和特殊镍作为过渡层,然后在其基础上刷镀快速铁,并使用扫描电镜和划痕结合强度测量仪,分别检测了表面形貌和结合强度。结果表明:这两种过渡层与基体和快速铁镀层结合较好,分层现象明显。快速镍作为过渡层时,结合强度最高约30.07 N。 Rapid nickel and special nickel were selected as the transition layer, and then rapid iron was brushed on the base. Scanning electron microscopy and scratch bond strength measuring instrument were used to test the surface morphology and bonding strength respectively. The results show that the two kinds of transitional layer combine well with the matrix and rapid iron plating, and the delamination phenomenon is obvious. Fast Nickel as a transition layer, the highest bonding strength of about 30.07 N.
