Tribological Properties of (EN AW-AlCu4MgSi(A)) Aluminium Alloy Surface Layer After Ball Burnishing

EN AW-AlCu4MgSi(A) aluminium alloy is widely used as a structural material in aerospace and automotive applications. We have subjected it to grinding, polishing and ball burnishing. We have performed ball-on-disk tribological tests. We have also determined normalized 3D roughness parameters. High surface smoothness turns out to be obtainable. Favorable effect of the ball burnishing on the tribological properties of the alloy are seen. Results will be presented at the Conference. DOI:  https://doi.org/10.15544/balttrib.2015.11
