| 摘 要： | 在Ｍ－２００磨损试验机上于无润滑、蒸馏水润滑、乳化液润滑和１０＾＃机构油润滑４种条件下，对Ｓｉ３Ｎ４陶瓷分别与灰铸铁ＨＴ和Ｔ８钢配副进行了摩擦损性能的对比试验研究。结果表明：Ｓｉ３Ｎ４陶瓷与灰铸铁ＨＴ配副时的摩擦因数和磨损体积在几种润滑环境中均表现出同样的顺序

| Abstract: | The friction and wear of ceramics Si 3N 4 against gray cast iron and 0.8% carbon steel under four lubricated conditions of dry friction,distilled water, emulsion and 10 # machinery oil have been studied in a ring block type wear tester. It is concluded that friction factor and wear are deceased in the order of dry friction,distilled water,emulsion and 10 # machine oil.Specially, friction factor is about 0.13 in emulsion and down to 0.02 in distilled water because the lubricating film containing graphite is formed on worn surface of gray cast iron in distilled water.The graphite can be taken as a solid lubricant in air and distilled water,but it can not in emulsion and oil. |
