1. 把Al22Si合金的 耐磨性和鑄鐵比，得出 Al22Si的 耐磨性 在某一點(diǎn)之后 才會(huì) 好于 鑄鐵，并分析了原因。
Comparing Al22Si alloy with cast iron in terms of abrasive resistance, it can conclude that the abrasive resistance of Al22Si is not higher than that of cast iron until passing certain point, and the reason within was analyzed.
2. 用硬度 評(píng)論 Al22Si的 耐磨性 是 不科學(xué)的，應(yīng) 充分考慮 合金的 微觀結(jié)構(gòu)。本文 具體闡述了 其原因，并和 傳統(tǒng)材料鑄鐵 做了對(duì)比。
It is not scientific to evaluate the abrasive resistance of Al22Si using the term of hardness, instead the microstructure of Al22Si alloy should be fully considered. This paper presented specific reason for this situation and made comparison between Al22Si alloy and conventional material-cast iron. |
