摘      要：Plasma nitriding is a widely used technology to enhance the surface performance and extend the service life of alloy *** current research mainly focuses on the influences of time,temperature,gas type and pressure parameters on nitriding behavior,while fewer studies have been conducted on the electric *** paper mainly reports the effect of the electric potential on nitriding *** conditions were set using cathodic,anodic and floating potentials in a plasma nitriding furnace.2Cr13 stainless steel was nitrided at 450°C for 5h in an NH3 *** experimental results show that the nitriding treatment can be well performed under the different electric potentials,but differences exist in microstructures,morphologies and performance results of the modified *** thickness and hardness values of the nitrided layer are ranked as follows:cathodic[anodic[floating *** anodic nitrided surface has an obvious particle deposition layer composed of nitrides and *** and tribological experiments show that the corrosion resistance and wear resistance were significantly improved after a nitriding treatment using the three electric ***,the floating nitriding treatment resulted in the best tribological performance and corrosion resistance.
