(3)選用“外表工程技能”,辦法如下: (a)電鍍技能:在柱塞外表鍍一層硬鉻;(b)電刷鍍技能:在柱塞外表刷鍍資料;(c)熱噴涂或電弧噴涂或電噴涂:噴涂高碳馬氏體資料;(d)熔敷:在柱塞外表熔敷高硬度合金粉末。

(4)缸體孔無銅套的缸體資料大都是球墨鑄鐵的,在缸內(nèi)壁上制備非晶態(tài)薄膜或涂層。因為缸體孔內(nèi)壁有了這種分外物質(zhì),所以才調(diào)構(gòu)成硬—硬配對的磨擦副。假定盲目地研磨缸體孔,把缸體孔內(nèi)壁這層外表資料研掉,磨擦的構(gòu)造功用也就改變了。被去掉涂層的磨擦副,假定強行運用,就會磨擦面溫度增加,柱塞桿與缸孔發(fā)作膠合。
