“…Generally, the nitrided surface can be seen under an optical microscope as a layer of compounds commonly referred to as a white layer in the outermost part of the surface, followed by the diffusion zone. The nitriding processes traditionally used in industry, which are distinguished by the nitriding medium, are gas nitriding and salt bath nitriding, but plasma nitriding has gained importance in the last decade in the processing of special steels [49][50][51][52][53][54] .…”

The automotive industry is one of the largest industrial segments in the world market. The exhaust system of motor vehicles is responsible for the emission and treatment of toxic gasses released by the engine. In this sense, the application of titanium on an AISI 1020 steel substrate was carried out by plasma deposition using a cathode cage. The aim of this research was to evaluate the application of this material in the exhaust system of motor vehicles. The samples were characterized by scanning electron microscopy (SEM), confocal microscopy (CM), microhardness tests and corrosion resistance tests. The samples exhibited a thin film with higher titanium content and hardness than the uncoated sample. The corrosion potential also increased and the current density was lower than the uncoated sample. The conclusion is that the deposition of thin titanium films on AISI 1020 steel with CCPD has the potential to produce thin films.

“…Increasing the nitrogen potential and adding methane preferably leads to the formation of a layer of (3N-Fe 2 ) type nitride compounds. It is very important to remember that the chemical composition of the substrate plays an important role in the metallurgy of the nitrided surface 47,49,[55][56][57][58][59][60] .…”
