摘要
对Mn13Cr2高锰钢进行了爆炸硬化处理,并以120#氧化铝砂纸为磨料,应用ML-10型滑动磨损试验机对比研究了爆前、爆后高锰钢的滑动磨损性能,以探讨爆炸硬化对高锰钢滑动磨损性能的影响。结果表明:爆后高锰钢的滑动耐磨性是爆前的1.07～1.32倍,爆炸硬化弥补了高锰钢在滑动磨损过程中加工硬化能力的不足,使其滑动耐磨性得到有效改善。爆后高锰钢磨面仅出现少量氧化铝磨料,磨损产生的犁沟和划痕明显浅而窄,且磨损面相对平整、光滑。
In order to explore the effects of explosion hardening on the sliding wear behavior of Mnl3Cr2 high manganese steel, the steel treated with explosion hardening, and sliding wear behavior of the steel, before and after explosion hardening, was studied under experimental conditions by using dynamic load abrasion tester MLD-10 as experimental machine and alumina sand paper with model of 120° as abrasive. The results indicate that the sliding wear properties of exploded high-manganese steel is 1.07-1.32 times higher than the unexploded steel, thus it can be seen that the explosion hardening can compensate for the lack of work hardening ability during the slide friction process and can improve the sliding wear properties of high manganese steel. A few alumina abrasive appears on the surface after explosion hardening, and the furrow and scratch due to mechanical wear is obvious narrow and shallow.
