More than kinds of wear-resistant material wear resistance
Wear is a very complex process, the wear and wear characteristics of the abrasive nature of the process, the material properties and the interaction itself, and other factors related to system characteristics, only the specified only when certain operating conditions for a flap wheel variety of wear-resistant material abrasion resistance for comparison. In this paper, the above understanding of the material abrasion departure, chose the most commonly used in industrial production of high chromium cast iron wear-resistant material; own research our group wear new high vanadium alloy; and very representative bainitic Wear steel three series of 7 different typical wear-resistant material, the abrasive quartz sand and cement clinker, 2kg/cm ~ 2,5 kg / cm ~ 2,10 kg / cm ~ 2, three different impact loads the three series of different anti-wear material impact abrasive wear characteristics were studied in mini flap disc order for these wear-resistant material for comprehensive evaluation of anti-wear performance. Research was supported by the following main conclusions: The experimental results show that the microstructure observation and analysis, high-vanadium alloy series carbide sample microstructure of the matrix organizational fragmentation smallest, high chrome cast iron, followed by metallographic specimens bainitic steel series organization does not have the hard phase. Experimental results show that the mechanical properties, due to the high vanadium alloy series sample macro highest hardness, impact toughness with the second, so the wear resistance of the material with the most favorable. Experimental results show that the impact abrasive wear, abrasives and different impact on different loads, three series of high wear-resistant material vanadium alloy series the best wear resistance, high chrome cast iron, followed by the worst series bainitic abrasive tools steels. Among them, high chromium cast iron series, low load, Cr2 best abrasion resistance; higher loads, Cr3 abrasion advantage. High vanadium alloy series, V1 best abrasion resistance. Bainitic steel series, B1 best abrasion resistance. Moreover, the abrasion resistance of Cr3 as 1:00, Cr1, Cr2 relative abrasion resistance are increased with decreasing the impact load of the trend; the abrasion resistance as 1:00 V2, V1 with the relative abrasion resistance impact load increases gradually decreased; when the abrasion resistance as 1:00 B2, B1 relative abrasion resistance with increasing load on a downward trend. Further analysis of the experimental results obtained: Experiment two kinds of abrasives, high-vanadium alloys and high chromium cast iron two series with a lower impact on the occasion better show its excellent abrasion resistance. With quartz sand as abrasive when compared to the abrasive cement clinker, the high-vanadium alloy series and high chromium cast iron series bainitic steel series on the relative abrasion resistance increases. Paper also compares the sample is not the same abrasive wear weight loss and relative abrasion resistance, so as to arrive: abrasives softer, high aggregate I hunger and high chromium cast iron two series of samples allowed to play a more abrasion points; same load different! worship half inch a company who l a Lee, J Kang mill grinding material losses vary _L _ credits completed if the small mountain with abrasive not!, J nature of the decision.
