And the combination of ferrite gray iron and Ni-based alloy was better than that of pearite gray iron. Morever the microhardness of substrate and coating had a gradient distribution because of diffusion.
试验表明,在基体与覆层熔覆的过程中存在着元素的相互扩散,促进了二者之间的冶金结合,且铁素体基灰铸铁与镍基覆层之间的结合好于珠光体基灰铸铁,另外由于元素的扩散使基体与熔覆层组织的显微硬度呈梯度分布。
