The direct bonding joint between cemented carbide and nodular cast iron and the indirect bonding joint by using nickel foil as intermediate layer were obtained by HIP diffusion bonding process.

用热等静压扩散连接法获得了硬质合金与球墨铸铁的直接连接接头和以镍箔为中间夹层的间接连接接头。

It has been reported that an intermediate layer can have significant impact on the chemical bonding between a HAP coating and a metallic substrate.

据文献报道，中间过渡层可以对HAP涂层和金属基体之间形成化学骨连结产生重要影响。

The results show that there is an obvious bright intermediate belt between cladding alloy layer and the body, forming good metallurgic bonding.

结果显示，熔覆层与机体之间有明显的白亮过渡带，形成了良好的冶金结合。
