چکیده
In this study, we propose a rapid plasma-assisted nitriding process using H2/N2 mixture gas in an atmospheric pressure plasma jet (APPJ) system to treat the surface of SKD11 cold-working steel order increase its hardness. The generated NH radicals region are used implement ion-bombardment for tempered martensite structure within 18 min form functional nitride layer with increased microhardness around 1095 HV0.3. Higher ratios H/E and H3/E2 were obtained values 4.514 × 10−2 2.244 10−2, referring higher deformation resistance as compared pristine sample. After multi-cycling impact tests, smaller shallower craters less oxidation on plasma-treated distinctly proven have wear resistance. Therefore, can enable thermochemical protective unique advantages that deformation-resistance impact-resistance, improving lifetime tool die materials.

متن کاملOn the plasma chemistry of a cold atmospheric argon plasma jet with shielding gas device
A novel approach combining experimental and numerical methods for the study of reaction mechanisms in a cold atmospheric Ar plasma jet is introduced. The jet is operated with a shielding gas device that produces a gas curtain of defined composition around the plasma plume. The shielding gas composition is varied from pure N2 to pure O2. The density of metastable argon ( ) Ar 4s, P 3 2 in the pl...

متن کاملDischarges in N2 flowing gas for steel surface nitriding
2014 Modelling of plasma reactors for steel surface nitriding has been achieved in discharge and postdischarge conditions of N2 flowing gas. Diagnostics and calculations have been focused on the N2(X, V) vibrational molecules and N atoms which are the most populated long living species. It has been demonstrated that these neutral active species produce steel surface nitriding with the same char...
