subsurface layer - Opis:
- This paper characterizes mechanical properties of the technological subsurface layer produced by medium milling of EM AW-AlCu4MgSi(A) aluminium alloy in hardened state T451 using a ball-end cutter and subsequent roller burnishing using a nitride ceramic ball. It was revealed that ball burnishing operations performed on curvilinear milled surfaces allow obtaining the subsurface layer with a minimum strain-hardening effect and induced compressive residual stresses without visible microstructural changes. As a result, such functional properties of the subsurface layer as fatigue strength, bearing properties and contact strength along with a very smooth machined surface of the Sa roughness of about 0.02 µm can be ensured.
