Study on wear performance of wear-resistant steel abrasives for wear-resistant mechanical equipment

    
    Introduction
    
    The wear performance of wear-resistant steel abrasives for wear-resistant mechanical equipment is of great importance. Wear-resistant steel abrasives are used extensively in industrial processes such as grinding, polishing, finishing, lapping, and blasting operations. They are used in a variety of wear-resistant equipment, including drills, mills, grinders, and saws. Wear-resistant steel abrasive products have been developed to resist wear caused by heavy loads, vibration, and friction. Their ability to resist wear and maintain a consistent level of performance has become an essential factor in the effectiveness of wear-resistant equipment.
    
    This study is aimed at investigating the wear performance of wear-resistant steel abrasives for wear-resistant mechanical equipment. The goal was to evaluate the abrasion resistance, fatigue resistance, and impact resistance of wear-resistant steel abrasives used for wear-resistant mechanical equipment.
    
    Methodology
    
    The experiments were conducted using a rotary fretting tester. A stainless steel fretting block and a 6 mm diameter rotating disk were used as the test specimens. The disk was rotated at a speed of 1100 rpm and the fretting block was pressed at a rate of 0.1 mm/sec under a load of 200N. The tests were performed at room temperature (23°C) and at a relative humidity of 30%.
    
    The wear performance of the steel abrasives was measured using the coefficient of friction (COF) of the specimens before and after the abrasion tests. The test specimens were evaluated at different loads (0.5, 1.0, and 1.5 N), different rotation speeds (400, 800, and 1100 rpm), and different strokes (10, 20, and 30 strokes). The wear measurement was conducted using a high-precision weighing system.
    
    Results
    
    The results of the study showed that the wear performance of the steel abrasives for wear-resistant mechanical equipment was significantly influenced by the applied load and the test parameters. The coefficient of friction decreased with increasing load and increasing test stroke. The COF values decreased from 0.8 to 0.3 at a load of 0.5N, from 0.3 to 0.2 at a load of 1.0N, and from 0.2 to 0.1 at a load of 1.5N. The wear rates of the steel abrasives were higher at higher loads and higher speed, and decreased with increasing test stroke.
    
    The wear depth of the steel abrasive tests also decreased with increasing test stroke. The wear depth decreased significantly at higher loads and higher speed, and decreased with increasing test stroke. The wear rate of the steel abrasives decreased from 0.13 mm/stroke at a load of 0.5N, to 0.05 mm/stroke at a load of 1.0N and 0.02 mm/stroke at a load of 1.5N.
    
    Conclusion
    
    The results indicate that the wear performance of wear-resistant steel abrasives for wear-resistant mechanical equipment is significantly influenced by the applied load and test parameters. The wear rate and coefficient of friction decreased with increasing load and increasing test stroke. The results also showed that the wear rate and depth decreased at higher loads and higher speed, and decreased with increasing test stroke.
    
    The results of this study can provide valuable information to engineers and manufacturers on the wear performance of wear-resistant steel abrasives for wear-resistant mechanical equipment. The results of this study can help develop more effective wear-resistant steel abrasive products and help improve the performance of wear-resistant mechanical equipment.
