- Abstract
In this paper, high manganese steel with cone crushing motor cone lining plate is selected, and the sliding friction and wear experiments of 50 N, 100 N and 150 N loads were carried out in different media environments (dry friction, deionized water solution, 3.5 wt.% NaCl solution) by using Rtec-MFT 5000 tester. The wear mechanism was studied by the data collected by friction and wear experiments and the morphology analysis of the microstructure by scanning electron microscopy (SEM). The results showed that the friction coefficient of high manganese steel was the maximum in dry friction condition, and the minimum in deionized water solution. Under the same load, the wear volume in 3.5 wt.% NaCl solution was always the largest, followed by the dry friction in deionized aqueous solution. This was because the overall wear was accelerated after adding water, especially with ionic solutions containing salts, the double damage of electrochemical corrosion and physical wear would occur, resulting in more serious wear. According to the pictures of the surface microstructure, it was found that the microstructure damage of the high manganese steel sample in 3.5% NaCl solution was the most serious, and the damage was the least in deionized aqueous solution. In conclusion, the high manganese steel material had the best wear resistance in deionized aqueous solution, followed by dry friction, and the worst wear resistance in 3.5 wt.% NaCl solution.
