It was also found that the protecting effect of erodents on the coating surface does exist. The protecting effect will be more evident if using erosion efficiency of unit mass erodent of sand in the slurry to describe the erosivity of erodent. Besides a model is proposed to explain the protection process. The wear mechanism of the coating is the co-operation of ploughing, cracking and ablation.

对涂层的SEM分析可知，除冲蚀粒子在涂层表面的犁沟作用，冲蚀磨损的结果造成涂层的表面生成了系列针孔，其中的一部分为溶剂挥发所至，另外还存在由增强颗粒的剥落和裂纹的扩展造成的涂层剥落产生的孔洞，这将可能为水的吸收和扩散造成有利条件，使复合涂层亚表层产生内应力。

The results of the investigation showed that the best entrance angle of B〓C, B〓C/ C and Al〓O〓/ C ceramic nozzles is 11°, 14°and 16°respectively. Erosion wear model has been put forward.

EM analysis the worn surface morphology shows the following results: elastic deformation and fatigue are the main wear mechanisms of SMCC when impacted with lower erodent velocity, while the dominant mechanisms change into microcutting and microploughing with the increment erodent velocity.The slurry erosion behaviors of ceramic particles reinforced epoxy matrix composite coating were explored using a self-designed slurry pot tester.

首次采用自制的模拟罐式泥浆冲蚀试验机对环氧基复合涂料的泥浆冲蚀磨损性能进行了研究，通过调整固化剂聚酰胺与环氧的质量比，设计出最佳的基体组成；尽管涂层的铅笔硬度对其抗冲蚀性能有一定的影响，但起决定性作用的因素是涂层的韧性和硬度有机结合。

It is noted that the microstructure of the blade material much affects the abrasive erosion pattern and erosive wear mechanism.

分析了材料的微观组织结构对材料表面的冲蚀磨损形貌、磨损机理的影响作用。

此外埃弗特，如网球明星萨巴蒂尼和小威廉姆斯也知道穿这些美丽的手镯。

In this research, Delphi language is adopted to work out calculation procedure of coal-pulverizing system, use this procedure to perform checking calculation, and act as the theoretic basis of operating adjustment. The operation characteristics and controllable parameters are completely studied to reduce the cost. The double-stage separating technique is adopted to improve separation efficiency. The pulverized coal exhauster is reformed based on the outcome of resistance calculation to save power consumption of pulverized system. The wearing problem of steel balls is studied, has set up the stable state mathematics model of steel ball wear to certain load ball system and addition ball system.
