中文摘要:
      目的 探索含双氧水磨液对铝合金试件滚磨光整加工后表面质量的影响及作用机理。方法 在相同条件下,配制含不同浓度双氧水的磨液作为液体介质,对铝合金试件进行滚磨光整加工实验及摩擦磨损实验,测量铝合金试件滚磨光整加工前后的表面粗糙度值,并表征铝合金试件滚磨光整加工前后的表面形貌以及摩擦磨损实验后的磨痕形貌。分析摩擦磨损实验后,铝合金试件表面元素的变化情况,以及滚磨光整加工后,铝合金试件硬度随表面深度的变化情况。结果 含双氧水磨液作用下的试件的表面粗糙度值下降率大于去离子水条件下的值,且其摩擦系数和磨损量明显小于去离子水及干式摩擦磨损作用下的值。试件表面初始粗糙度值较小时,含双氧水磨液对滚磨光整加工铝合金试件的作用明显,其中双氧水体积分数为0.3%的磨液作用下Ra从未加工时的0.220 μm减小到0.055 μm,表面粗糙度值下降率为74%。结论 含双氧水的磨液对较低初始表面粗糙度值的铝合金试件经滚磨光整加工后的表面质量具有重要作用。由于磨液对铝合金的吸附、润湿作用,使得其在滚磨光整加工中具有一定的润滑性、清洗性,并且摩擦作用下会使铝合金表面发生一定的摩擦化学反应。磨液中的双氧水加快了铝合金表面的腐蚀氧化反应,并将氧化产物以颗粒的形式拔出表面。滚磨光整加工作用硬化了铝合金表面,提高了其机械性能。
英文摘要:
      The work aims to explore the effect and mechanism of grinding fluid containing hydrogen peroxide on the surface quality of aluminium alloy specimen in barrel finishing. Under the same conditions, grinding fluid containing different concentrations of hydrogen peroxide were prepared as liquid media to carry out barrel finishing and friction and wear experiments on aluminium alloy specimens. The surface roughness of aluminium alloy specimens before and after processing was measured. The surface morphology of aluminium alloy specimens before and after barrel finishing was characterized. The wear scar morphology of aluminium alloy specimens after friction and wear experiments was also characterized. The changes of surface elements on the specimens after friction and wear experiments were analyzed. The changes of hardness of aluminium alloy specimens with surface depth after barrel finishing was also analyzed. The decrease rate of surface roughness under the action of hydrogen peroxide was greater than that under the action of deionized water. The friction coefficient and wear amount under the action of hydrogen peroxide were obviously smaller than those under the action of deionized water and dry condition. When the initial surface roughness of the specimen was small, the effect of the grinding liquid containing hydrogen peroxide on aluminium alloy specimen was obvious in barrel finishing. Under the action of the grinding liquid containing 0.3% hydrogen peroxide, Ra decreased from 0.220 μm to 0.055 μm, and the decrease rate of the surface roughness was 74%. As a result, the grinding fluid containing hydrogen peroxide can effectively improve the surface quality of aluminium alloy specimens with lower initial roughness after barrel finishing. Because of the adsorption and wetting effect of grinding liquid on aluminium alloy, the aluminium alloy has a certain lubricity and cleanliness in the barrel finishing, and the friction effect will cause a certain tribochemical reaction on the surface of aluminium alloy. The hydrogen peroxide in the grinding fluid accelerates the corrosion oxidation reaction on the surface of aluminium alloy and pulls the oxidation products out of the surface in the form of particles. Barrel finishing hardens the surface of aluminium alloy and improves its mechanical properties.
