金属材料泥沙磨损破坏微观形貌研究

Study on Micro Morphology of Metallic Material Damaged by Silt Erosion

本文对水轮机叶片常用材料的泥沙磨损破坏的宏观和微观形貌进行了分析,叙述了泥沙磨损的微观破坏过程及提高材料料耐磨损性能的途径。

In this paper, the macro-and microanalysis is made to silt erosion morphology of materials, commonly used for the hydraulic turbine blades are introduced. The paper also presents the micro course of silt erosion damage and the way to improve the abrasion-resisting properties of materials.
