Efecto de la modificación superficial por Fricción Agitación (PFA) en la dureza y el desgaste de la aleación de aluminio de la serie 6000

Abstract

This article presents the results obtained from the evaluation of the effects of the surface modification by Friction Stir processing (FSP) on an aluminum alloy of architectural use of the series 6063 are reported. The behavior of the material in the state of supply and of the modified material by FSP, microhardness analysis, metallographic analysis at macro and micro levels, wear analysis and coefficient of friction were performed using the Pin on Disk dynamic test. It was found that in general the surface modification produces a substantial improvement of the mechanical properties such as hardness when passing from 42 HV to 62 HV in the samples modified by (FSP) and the wear resistance in terms of mass loss was reduced in a 39% offering an important technological alternative to improve the in-service performance of these materials subjected to similar operating conditions.
