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

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

Article presents the 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. The authors have subjected it to grinding, polishing and ball burnishing. The authors 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 International Scientific Conference BALTTRIB, 2015.
