The current investigation aims at understanding the effect of friction stir processing (FSP) on wear behavior of Al-6061 T6 alloy. The study is aimed to understand the effect of processing without the addition of the reinforcement media. The variables of FSP are number of passes and direction of processing passes. Wear testing has been done for the processed samples and the unprocessed base metal. The processed samples show improvement in the wear behavior when compared to the base metal. With increase in number of processing passes, wear increases. With direction reversal between two consecutive passes, wear decreases. The enhanced surface properties of the processed samples are attributed to grain refinement, breaking and better dispersion of Mg₂Si precipitates after processing. An interesting observation made is that the standard error in wear measurement is reduced for the processed samples as compared to the base metal, indicating uniform surface properties for processed samples.

当前的研究旨在了解摩擦搅拌处理（FSP）对Al-6061 T6合金的磨损行为的影响。该研究旨在了解不添加增强介质的加工效果。FSP的变量是通过次数和处理通过的方向。已对已处理的样品和未处理的贱金属进行了磨损测试。与母材相比，加工后的样品显示出改善的磨损性能。随着加工次数的增加，磨损增加。在两个连续走刀之间反转方向时，磨损会减少。加工后样品的表面性能增强归因于晶粒细化，断裂和Mg _2的更好分散Si在处理后沉淀。有趣的观察结果是，与贱金属相比，加工样品的磨损测量标准误差降低了，这表明加工样品的表面性能均匀。
