三相磨料射流作用下材料的破坏机理研究

Study on the Damage Mechanism under the Three-phases Abrasive Jet

针对一种新型磨料射流形式 ,从摩擦学角度出发 ,分析材料在其作用下的破坏机理。结果表明材料磨蚀主要由冲蚀磨损、气蚀破坏以及它们的共混蚀损作用造成的。特别是共混蚀损 ,它是三相流中一种独特的现象 ,相互制约 ,相互促进 。

Aimed at a new type of abrasive jet, from the view of tribology, the damage mechanism of materials is analyzed The result shows that the abrasion of materials is mostly made by the impact erosion, cavitation erosion and coexistent erosion and damage, especially for coexistent erosion and damage, which condition each other and speed up the damage of materials
