Year: 2024
Type: article
Abstract: In this work, the cathodic cage plasma deposition (CCPD) technique was applied to SAE 5160 steel, using Hastelloy cathodic cage (nickel alloy) with the aim of increasing the surface hardness and wear resistance of this steel. The deposition treatments were carried out with the samples at cathodic potential. In this work, two different atmosphere conditions were studied (75%H2/25%N2 and 25%H2/75%N2), at a temperature of 450°C during 4 hours. The coatings formed were analyzed using X-ray diffraction, optical microscopy, Vickers microhardness and microabrasive wear tests. Both treatment conditions favored the formation of coatings with high microhardness and excellent adhesion to the substrate. The treatment carried out in the most hydrogen-rich atmosphere (75%H2/25%N2) showed greater layer thickness and superior wear resistance, with a reduction of around 65% in the worn volume.
