| 摘 要： | 通过ＳＥＭ观察和ＥＤＸＡ分析对Ａｌ２Ｏ３／ＳｉＣ和ＳｉＣｗ／ＳｉＣ陶瓷的耐磨粒磨损性进行了比较研究。在低应力下，Ａｌ２Ｏ３／ＳｉＣ陶瓷的耐磨性优于ＳｉＣｗ／ＳｉＣ陶瓷，而在较高应力下则相反。

| Abstract: | With the help of SEM and random EDXA analysis,abrasion behavior of Al2 O3/Si C and Si Cw/Si C ceramics are discussed. At low contact stresses,Al2 O3/Si C ceramics exhibit relatively better wear resistance than Si Cw/Si C ceramics.The overall effects of the plas- ticity,fracture toughness and hardness on abrasive wear are all important.The wear precess con- sists mainly of single particle dispatching and cluster spalling. |
