Some believe that the hardened gray iron used to make the components simply “fatigues” with age—as metal parts that go through millions of stress reversals eventually do.
有些人认为硬化的灰铸铁过去曾使零件很容易腐朽老化（因为经过数百万次的应力反向处理后的金属零件最后都会这样）。
The quantity, shape, size and distribution of graphite in gray iron influences the properties of material.

灰铸铁
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。
