砂浆冲蚀磨损特性研究

Study of Slurry Erosive Wear

用自制的砂浆冲蚀磨损试验机在水 -石英砂浆冲蚀条件下 ,对纯铝、 2 7SiMn钢和高铬铸铁等金属材料的磨损行为进行了试验 ,研究了不同材料的砂浆冲蚀磨损率与冲蚀速度及冲蚀角度的关系 ,分析了砂浆冲蚀磨损的特性和机理 ,提出了一种砂浆冲蚀磨损的刺入机制。

Pure A1, steel 27SiMn and high chromium cast iron are tested with a slurry erosion tester. The surfaces after erosion are observed and analysed. The laws and mechanisms of slurry erosive wear are investigated, and a stabbing mechanism is concluded.
