摘要

研究了45钢（阴极）表面电火花沉积两层镀层的显微组织、相组成和化学成分的分布。结果表明，由Ni或Cu形成的下层起到了抑制微裂纹从Ni - Al系合金镀层上层渗透到阴极的作用。两层涂层均具有由柱状晶构成的梯度结构，其中组分的浓度随厚度逐渐变化。

Structure of Combined Intermetallic Electrospark Coatings on Steel 45

The microstructure, phase composition and distribution of chemical components in two-layer coatings obtained by the method electrospark deposition (ESD) on steel 45 (cathode) are studied. It is shown that the lower layer formed by Ni or Cu acts as a damper preventing penetration of microcracks into the cathode from the upper layers of the coatings obtained from alloys based on the Ni – Al system. The two-layer coatings in all the cases have a gradient structure constituted by columnar crystallites, the concentration of components in which varies gradually over the thickness.
