Research on the Nitriding Effect of Ta-10W with Change of Process Parameters

Abstract:

Plasma nitriding is a thermochemical treatment method to make the metal surface reinforced. It can be used to significantly improve the surface hardness, abrasion resistance, fatigue strength, corrosion and erosion resistance. This paper presents a study of the influence of nitriding temperature and holding time on the nitriding effect while different nitriding process parameters are adopted on Ta-10W board samples by plasma nitriding technology. The result shows that nitriding temperature is the key parameter to the final effect of nitriding. Samples nitrided at 950 ^oC for 10h get thicker nitride layer and more nitrogen in nitride layer.
