無論用(yong)何種(zhong)加(jia)(jia)工(gong)方法加(jia)(jia)工(gong)，在(zai)零(ling)件表(biao)(biao)面(mian)總會留(liu)下微細的凸凹不平的刀痕，出現(xian)(xian)交錯起伏(fu)的峰谷(gu)現(xian)(xian)象，滾壓(ya)(ya)(ya)加(jia)(jia)工(gong)原理(li)：它是(shi)一(yi)種(zhong)壓(ya)(ya)(ya)力光(guang)整加(jia)(jia)工(gong)，是(shi)利用(yong)金(jin)屬(shu)在(zai)常(chang)溫狀態的冷塑(su)性(xing)(xing)(xing)(xing)特點，利用(yong)滾壓(ya)(ya)(ya)工(gong)具對工(gong)件表(biao)(biao)面(mian)施(shi)加(jia)(jia)一(yi)定的壓(ya)(ya)(ya)力，使(shi)工(gong)件表(biao)(biao)層(ceng)金(jin)屬(shu)產生(sheng)塑(su)性(xing)(xing)(xing)(xing)流動，填(tian)入到原始殘(can)(can)留(liu)的低凹波谷(gu)中，而達到工(gong)件表(biao)(biao)面(mian)粗糙值降低。由于被滾壓(ya)(ya)(ya)的表(biao)(biao)層(ceng)金(jin)屬(shu)塑(su)性(xing)(xing)(xing)(xing)變形(xing)，使(shi)表(biao)(biao)層(ceng)組(zu)織冷硬化和晶(jing)粒變細，形(xing)成致密的纖(xian)維狀，并形(xing)成殘(can)(can)余應力層(ceng)，硬度(du)和強度(du)提高，從(cong)而改善了工(gong)件表(biao)(biao)面(mian)的耐磨性(xing)(xing)(xing)(xing)、耐蝕性(xing)(xing)(xing)(xing)和配(pei)合(he)性(xing)(xing)(xing)(xing)。滾壓(ya)(ya)(ya)是(shi)一(yi)種(zhong)無切削的塑(su)性(xing)(xing)(xing)(xing)加(jia)(jia)工(gong)方法。45#絎(heng)磨管(guan)表(biao)(biao)面(mian)熱處(chu)理(li)具體定義

45號絎磨(mo)(mo)管(guan)(guan)采用(yong)加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝技術(shu)絎磨(mo)(mo)管(guan)(guan)采用(yong)滾壓(ya)(ya)(ya)加(jia)工(gong)(gong)(gong)(gong)，由于表(biao)(biao)(biao)面(mian)層(ceng)留有(you)表(biao)(biao)(biao)面(mian)殘余(yu)壓(ya)(ya)(ya)應(ying)力(li)(li)，有(you)助于表(biao)(biao)(biao)面(mian)微小裂紋的(de)封閉(bi)，阻礙(ai)侵蝕(shi)作(zuo)用(yong)的(de)擴(kuo)(kuo)展。從(cong)(cong)而(er)(er)提高(gao)表(biao)(biao)(biao)面(mian)抗腐蝕(shi)能力(li)(li)，并(bing)能延緩疲勞裂紋的(de)產(chan)生(sheng)或(huo)擴(kuo)(kuo)大，因而(er)(er)提高(gao)絎磨(mo)(mo)管(guan)(guan)疲勞強(qiang)度(du)(du)。通過(guo)滾壓(ya)(ya)(ya)成(cheng)型，滾壓(ya)(ya)(ya)表(biao)(biao)(biao)面(mian)形成(cheng)一(yi)層(ceng)冷(leng)作(zuo)硬化(hua)層(ceng)，減(jian)少了(le)磨(mo)(mo)削副接觸表(biao)(biao)(biao)面(mian)的(de)彈性(xing)和(he)塑(su)(su)性(xing)變(bian)形，從(cong)(cong)而(er)(er)提高(gao)了(le)絎磨(mo)(mo)管(guan)(guan)內壁的(de)耐磨(mo)(mo)性(xing)，同(tong)時避(bi)免了(le)因磨(mo)(mo)削引起的(de)燒傷。滾壓(ya)(ya)(ya)后，表(biao)(biao)(biao)面(mian)粗糙度(du)(du)值的(de)減(jian)小，可提高(gao)配合性(xing)質。滾壓(ya)(ya)(ya)加(jia)工(gong)(gong)(gong)(gong)原理：它是一(yi)種壓(ya)(ya)(ya)力(li)(li)光整(zheng)加(jia)工(gong)(gong)(gong)(gong)，是利(li)用(yong)金屬在(zai)常溫狀態的(de)冷(leng)塑(su)(su)性(xing)特點，利(li)用(yong)滾壓(ya)(ya)(ya)工(gong)(gong)(gong)(gong)具對工(gong)(gong)(gong)(gong)件表(biao)(biao)(biao)面(mian)施(shi)加(jia)一(yi)定的(de)壓(ya)(ya)(ya)力(li)(li)，使工(gong)(gong)(gong)(gong)件表(biao)(biao)(biao)層(ceng)金屬產(chan)生(sheng)塑(su)(su)性(xing)流動，填入到(dao)原始殘留的(de)低凹波谷(gu)中(zhong)，而(er)(er)達到(dao)工(gong)(gong)(gong)(gong)件表(biao)(biao)(biao)面(mian)粗糙值降(jiang)低。由于被滾壓(ya)(ya)(ya)的(de)表(biao)(biao)(biao)層(ceng)金屬塑(su)(su)性(xing)變(bian)形，使表(biao)(biao)(biao)層(ceng)組織冷(leng)硬化(hua)和(he)晶粒變(bian)細，形成(cheng)致密的(de)纖維狀，并(bing)形成(cheng)殘余(yu)應(ying)力(li)(li)層(ceng)，硬度(du)(du)和(he)強(qiang)度(du)(du)提高(gao)，從(cong)(cong)而(er)(er)改善了(le)工(gong)(gong)(gong)(gong)件表(biao)(biao)(biao)面(mian)的(de)耐磨(mo)(mo)性(xing)、耐蝕(shi)性(xing)和(he)配合性(xing)。
