style="text-indent:25px">汽車零件失效的幾種形式：1、穴蝕：穴蝕是一種比較復(fù)雜的破壞現(xiàn)象,它是機(jī)械、化學(xué)、電化學(xué)等共同作用的結(jié)果.當(dāng)液體中含有雜質(zhì)或磨料時(shí)會加速破壞過程.穴蝕常發(fā)生在柴油機(jī)缸套的外壁、水泵零件、水輪機(jī)葉片、液壓泵等處.2.斷裂斷裂是零件在機(jī)械力、熱、磁、聲響、腐蝕等單獨(dú)或聯(lián)合作用下,發(fā)生局部開裂或分成幾部分的現(xiàn)象.斷裂是零件破壞的重要原因致意,它是金屬材料在不同情況下,當(dāng)局部裂紋發(fā)展到零件裂縫尺寸時(shí),剩余截面所承受的外載荷超過其強(qiáng)度極限而導(dǎo)致的完全斷裂.斷裂是零件使用過程中的一種較危險(xiǎn)的破壞形式.斷裂往往會造成重大事故,產(chǎn)生嚴(yán)重后果。剛度和承載能力與重量大5倍多的鋼片彈簧相當(dāng)。倫福德機(jī)油控制閥價(jià)格</p><p
