Abstract

The purpose of this work is show the propertiesagainst the corrosion of the aluminum alloy 6063by means of the process of hard anodizing. In theobtaining of the coating they are had as variablethe time of immersion in the sulfuric acid bath15% in weight to a temperature of 0±3 ºC (20, 50and 80 minutes) and the density of current (2.7, 4and 5 A/dm2). The rank of obtained thicknessesgoes from 23.3 to 125.5 micrometers. The microhardnessto the alloy and the hard anodizing wereobtaining that with the process of hard anodizing,
