離子滲碳 的英文怎麼說
中文拼音 [lízishèntàn]
離子滲碳
英文
ion carbonization-
Chloride ion permeability coefficient of c20 concrete and c30 concrete reduces after concrete surface is treated by reinforcing agent, and soakage reduced too. so the impermeability and carbonization resistance of concrete, especial c20 concrete, increase
塗刷耐久性增強劑后， c20和c30混凝土的氯離子擴散系數降低，吸水量減小，抗滲和抗碳化性能提高，其中，對c20混凝土的效果更為明顯。Abstract : the paper analyzes the wear resistance and anti - adhesion of 20 and 45 steel formed in austenitic ion - nitrocarburising and comparisons to the general ion - nitrocarburising. the experiment shows that austenitization - nitrocarburising can be carried out at 590 700, its wear resistance and anti - adhesion is the best at 630 ， the worst at 660 and anti - adhesion is the best at 630 ， the worst at 660 and the mediate at 570 600. with the help of raising processing temperature properly and speeding up the process the wear behavior can be improved
文摘:研究20鋼、 45鋼經奧氏體離子氮碳共滲后的耐磨性和抗咬合性，並與普通離子氮碳共滲后的作了比較，試驗表明:在570 700范圍內進行離子氮碳共滲后，其耐磨性和抗咬合性以630處理時為最佳， 660處理時最差，而570 600處理時則介於兩者之間，通過適當提高共滲溫度，再提高滲速，從而縮短共滲時間的同時，可以提高耐磨損性能。Strengthening mechanism of ion nitriding is different from surface quenching and cementation, which makes surface strengthen by quenching to get martensite. ionic nitriding is the way to make materials strengthe n, which result from the steady compound formed on the surface of the metal. there is no need for quenching after treatment
離子滲氮的強化機理不同於表面淬火，滲碳等表面熱處理方法，這些方法必須進行淬火得到馬氏體使表面強化，而離子滲氮是在金屬表面形成穩定化合物而使材料強化，處理后不須淬火。The company deals with the heat treatment processing of various specification, type and kind of ferrous nonferrous metal, including anneal, quenching, hardening tempering, carburizing, solid solution, aging, vacuum heat treatment, high frequency treatment, blueing, nitriding and ion nitriding etc, the annual capacity of which is more than 18, 000t
