Abstract
In mechanical systems, surfaces of machine parts are often requested and most exposed to the external phenomenon. These are of various natures such as friction, wear, corrosion, tiredness, etc. High mechanical performances of parts in service are conditioned by physical and geometrical properties of surface layers. These properties can be obtained by the choice of a material with high performances, these results on an increasing cost. One of the solutions which appear to be the simplest and the less expensive consist of integrating some structural modifications which can confer to a basis material an important new property on superficial layers. This study is focused on mechanical surface treatments giving particular properties to superficial layers of a steel piece in applying mechanical surface treatments based on a Superficial Plastic Deformation (SPD) such as the ball burnishing. The analysis of the results obtained by applying this treatment on premachined (turned) samples, offers significant improvements in surface Roughness (Ra) and superficial Hardness (Hv). These two properties seem to be strongly linked to treatment parameters which their effects are studied in this research work. As a result a specific optimal regime to each characteristic (Ra and Hv) is defined in order to obtain a maximum effect.
