Abstract:

针对内蒙古中西部地区钢结构体系表面涂层长期遭受风沙环境冲蚀的这一现状,采用气流挟沙喷射法,模拟风沙对钢结构涂层的冲蚀.研究了风沙冲蚀力学参数对钢结构涂层冲蚀率的影响;探讨了涂层冲蚀损伤的摩擦学机理;分析了钢结构涂层的冲击摩擦因数变化规律.结果表明:涂层的冲蚀率均随着冲蚀速度呈指数增长,速度指数n为2.39~2.43;在45°时涂层的冲蚀率最大,90°时涂层的冲蚀率最小,低冲角时的冲蚀率大于高冲角时;涂层的摩擦因数处于0.37~0.42,涂层磨损的Taber指数为81.9×10-3mg/r,涂层的耐磨性较差.涂层损伤的摩擦学机理是:低冲角时的微切削作用或高冲角时的挤压凿削作用造成涂层的损伤占主导,涂层表面微裂纹扩展交叉,以致断裂剥落,造成的损伤次之;涂层冲击摩擦因数离散性较大,且随角度增长呈降低趋势;冲击摩擦因数与冲蚀率随角度的变化并不一致.
