Abstract
The thermochemical treatment of Pulsed Plasma Nitriding is employed as an alternative to improve the surface properties of metals, such as: increase surface hardness, improve wear resistance, extend fatigue life and also create a barrier to the diffusion of hydrogen into the steel to reduce the susceptibility to hydrogen embrittlement . In this study, the effect of such treatment on ASTM A36 steel is analyzed through two different nitriding conditions: 5 h and 660 Pa for the first condition and 15 h and 720 Pa for the second one. In both cases, the temperature was held at 300 °C. Thus, in order to verify the results, Vickers hardness analysis and metallographic observation were carried out under an optical microscope. Only the second condition was able to achieve what was proposed, the formation of a uniform nitriding layer and an expressive increase of hardening on the surface.
