The influence of glow discharge nitriding, oxynitriding and carbonitridingon surface modification of Ti-1Al-1Mn titanium alloy

Recent surface treatment studies show that titanium alloys should have an i mproved resistance to frictional wear and fatigue strength limit without an y loss of their high corrosion resistance. These requirements can be satisf ied by producing surface nitrided, oxynitrided and carbonitrided diffusion layers. This paper presents the results of metallographic examinations, cor rosion and wear resistance tests, surface chemical composition investigatio n, as well as rotating and bending fatigue tests. These surface treatments increase the useful properties of the titanium alloy. The influence of trea tment time and the thickness of the layers on its properties are also inves tigated.
