DIFFRACTION MEASUREMENT OF RESIDUAL STRESSES IN TRIBOLOGICAL TESTS OF ELEMENTS COVERED WITH LOW FRICTION COATINGS
Journal Title: Tribologia - Year 2015, Vol 264, Issue 6
Abstract
The aim of this article was to present the methodological assumptions of determining residual stresses in the surface layer of components undergoing tribological tests. The presented approach to residual stresses measurements includes a series of measurements conducted through the middle of the specimen friction track. The sin2ψ diffraction method, which is widely used in science and industrial sectors, was applied to determine the distribution of residual stresses. The cone-shaped samples from bearing steel 100Cr6 and high-speed steel SW7M were tested. By means of developed method the authors analysed the influence of WC/C and DLC coating deposition on the residual stresses of steel samples. The aplication of develped method makes it possible to determine the changes of residua stresses in the tribological samples.
