| 摘 要： | 对Q235钢表面铝镀层进行不同时间的微弧氧化处理从而在铝镀层表面获得不同厚度的陶瓷氧化膜.采用硬度测试仪、摩擦磨损试验机和扫描电子显微镜分别研究了氧化时间对陶瓷氧化膜厚度、表面硬度、摩擦磨损特性以及磨损试验后的磨痕形貌和微观结构的影响规律.结果表明:随微弧氧化时间的延长,铝镀层陶瓷氧化膜的厚度和硬度迅速增加,经微弧氧化处理30min后铝镀层的表面硬度较处理前增加了近7倍;在干摩擦条件下,铝镀层陶瓷氧化膜的磨痕宽度和磨损体积随微弧氧化时间的延长逐渐减小,而摩擦系数逐渐下降,表明耐磨性随微弧氧化时间的延长逐渐提高.铝镀层的磨损形式为表面压溃和锉削式磨粒磨损,处理时间为20min和30min的磨损形式为低应力擦伤性磨粒磨损,而处理10min的磨损形式介于上述二者之间.

| Abstract: | Aluminum coating on Q235 steel was treated by micro-arc oxidation (MAO) at various treated duration to get ceramic films with different thicknesses.By using hardness tester,friction and abrasion testing machine and scanning electron microscopy,the effect of treated time on thickness,hardness,friction and wear,morphology of wear trace and the microstructure after the abrasion experiment were investigated.The results indicated that the thickness and the hardness of the ceramic films increased quickly as the m... |
