Maximum tensile stress on a hard coating under sliding friction. D.F. Diao, K. Kato and K. Hayashi. Tribol. Internat. August 1994, 27(4), 267--272.
Mathematical expressions are developed for calculating maximum tensile stress at a friction surface in relation to friction coefficient, coating thickness, contact width, and elastic moduli of coating and substrate. The finite element method is used and the maximum tensile stress is obtained for a variety of material combinations and frictional conditions. A simple equation is recommended for calculating maximum tensile stress at the friction surface. This has an important application in predicting crack propagation in hard coatings used to extend the life of high-speed steel tools and stainless steel ball bearings. 13 refs.
