ANALYSIS OF BALL BURNISHING INFLUENCE ON TRIBOMECHANICAL PROPERTIES OF ALUMINUM

Abstract

In recent years, modern industry has been paying great attention to the environmental aspects of processing that relate to the elimination of processes requiring cooling and lubricating agents, whenever possible. Used equipment for cooling and lubrication, according to modern legal regulations, must be stored and destroyed in an appropriate manner, i.e. recycled, which increases the costs of business entities. On the other hand, the demands of the market in terms of geometric and dimensional accuracy are getting tougher, and it is therefore desirable that coarse and finishing workpieces are carried out in one clamping in order to eliminate baseline errors. To this end, a finishing tool has been developed without removing the chips from material, i.e. plastic deformation of the surface layer of the object of processing. This paper deals with the study of the influence of this type of treatment on the micro-hardness of the surface layer as well as on the wear resistance. The tests were carried out on aluminum alloy EN AW-6082 (AlMgSi1) T651.
