High-frequency impacting and rolling (HFIR) as a new surface strengthening treatment has been paid more and more attention. 2A12 aluminum alloy was processed by HFIR with different parameters. The effect of HFIR on friction and wear behavior of 2A12 aluminum alloy was investigated. Results showed that the surface roughness value of HFIR processed samples was decreased compared to the original samples. Compared with the original samples, the maximum surface microhardness of the HFIR treated samples ultimately increased by about 12.4%. The depth of hardened layer of about 135 μm can be obtained by HFIR treatment. The wear mechanisms of the HFIR-free samples were oxidation wear, abrasive wear and severe adhesive wear. The wear mechanisms of the HFIR-treated samples were abrasive wear, light adhesive wear and oxidation wear. Experimental results indicated that HFIR treatment is an efficient way to enhance the wear resistance of the 2A12 aluminum alloy.

高频冲击和轧制对2A12铝合金摩擦磨损性能的影响

高频冲击轧制(HFIR)作为一种新的表面强化处理技术已受到越来越多的关注。2A12铝合金通过不同参数的HFIR处理。研究了HFIR对2A12铝合金摩擦磨损性能的影响。结果表明,与原始样品相比,HFIR处理的样品的表面粗糙度值降低了。与原始样品相比,经HFIR处理的样品的最大表面显微硬度最终提高了约12.4%。可以通过HFIR处理获得约135μm的硬化层深度。无HFIR样品的磨损机理是氧化磨损,磨料磨损和严重的粘合剂磨损。经HFIR处理的样品的磨损机理为磨料磨损,轻质粘合剂磨损和氧化磨损。
