Tribological Evaluation of Magnetron-Sputtered Coating for Military Applications
Abstract
There is a continuing requirement for high-performance tribological coatings in both commercial and military applications. To maximize system performance, corresponding improvements in wear resistance, high-temperature stability, Corrosion behavior, and bearing durability must be realized. In our ongoing study, a number of different coatings were applied to 52100 bearing steel, 4340 steel, Inconel 718, and Ti-6Al-4V to improve wear characteristics, corrosion resistance, and rolling contact fatigue behavior. This report deals with CrN, TiN, W, and Ta coatings deposited by magnetron sputtering. Data on corrosion, Falex annular wear, ball-on-disk, and rolling contact fatigue are presented.
