Method for evaluating wear resistance and corrosion resistance of surface coating of coal mine hydraulic bracket

The invention belongs to the technical field of coal mine hydraulic bracket anticorrosive coating performance detection, and particularly discloses a method for evaluating wear resistance and corrosion resistance of a surface coating of a coal mine hydraulic bracket. The method comprises: placing a to-be-tested sample in an environment containing an acidic salt spray corrosion solution, an acidic gas and gravel, and testing. The method at least has one of the following beneficial effects: the method simulates the influence of conditions such as acid gas, an acid salt spray corrosion solution and gravel erosion and the like on the wear resistance and corrosion resistance of the surface coating of the coal mine hydraulic bracket, the defects of a single salt spray resistance test evaluation method are overcome, and the wear resistance and corrosion resistance of the surface coating of the coal mine hydraulic bracket can be evaluated more accurately. 本申请属于煤矿液压支架防腐涂层性能检测技术领域，具体公开了一种煤矿液压支架表面涂层耐磨耐腐蚀的评价方法，包括将待测样品置于含
