| 为了减少材料和能源的损耗,延长零部件使用寿命,硬质涂层被应用于喷砂型冲蚀磨损环境。本文介绍了喷砂型冲蚀磨损的危害和硬质涂层抗喷砂型冲蚀磨损的应用情况,从硬质涂层力学性能、基体材料性能、粒子特性和粒子喷砂工艺参数等方面综述了对涂层抗喷砂型冲蚀磨损的影响趋势,发现目前还没有理论和模型可以全面解释硬质涂层的抗喷砂型冲蚀磨损机理。总结了喷砂型冲蚀磨损的动力学模拟和冲击试验的研究情况,指出了涂层硬度和韧性以及基体与涂层性能的匹配对提高涂层抗喷砂型冲蚀磨损有益,展望了通过数字模拟与试验验证相结合的方式获得各种硬质涂层抗喷砂型冲击磨损机理模型的前景。 |

| In order to prolong the service life of parts and reduce the loss of materials and energy, hard coatings are applied to sandblasting erosion wear environments. This paper introduces the harm of sandblasting erosion wear and the application of hard coating against sandblasting erosion wear. The influence trend of hard coating mechanical properties, matrix material properties, particle properties and particle sandblasting process parameters on sand blasting erosion wear were reviewed. Existing studies show that there is no theory and model to fully explain the erosion wear mechanism of hard coatings. The research situation of dynamic simulation and impact test of sandblasting erosion is summarized. It is pointed out that the hardness and toughness of the coating and the matching of substrate and coating properties are beneficial to improve the resistance of the coating to sand blasting erosion wear. The prospect of the impact wear mechanism models of various hard coatings against sandblasting is prospected by combining digital simulation with experimental verification. |
