EN-31 steel doesn't work well in tribology because it wears down AA6082-T6 in a way that can't be stopped. Surface wear is also affected by how AA6082-T6 is made mechanically: To make AA6082-T6 less likely to wear out, its mechanical properties must be improved. Friction Stir Processing (FSP) has been used to make Al/B4C composites, but the AA6082-T6/B4C composite has not been studied under multi-pass (one, two, and three pass) conditions. In this study, multi-pass FSP is used to make a surface composite (AA6082-T6/B4C) and then applied to the material to optimize its microstructure, mechanical properties, and how it wears. Use it with the stuff. This study looks at how different passes affect the microstructure, tensile strength, surface roughness, phase composition, and wear rate of a material. The three pass condition decreases the size of the particles and evens out the distribution of B4C, which improves the microstructure. The microhardness of AA6082-T6/B4C was 2.5 times that of its father. The Ultimate Tensile Strength of a three-pass FSPed composite went up because the B4C particle and the Al matrix stuck together very well (UTS). After three passes of FSPed, the AA6082-T6/B4C composite goes from being very sticky to being only slightly rough. Sticky wear is not as rough as abrasive wear.
