Optimization of wear and cracks in roller contact under different coating and a range of loads and temperature with fixed speed using design expert (DOE) and finite element model

Superior coating technology and roller materials such as M50 steels (0.8C–4.2Cr–4.3Mo–1V wt. %) (1.0C–2.0Cr–0.5Mo–1.0Mn– 0.5Si are well recognized in modern technology. The aim is to present all the external internal parameters that affect rolling system by taking into consideration microstructure importance identifying service life of technique. most dangerous defects cracks wear under high loading contact temperature formed during process.Finite elements method was used simulate calculate extensive order use DOE optimize several conditions from load temperature. analysis involved here steel rollers with without coatings, which include titanium nitride (TiN), zirconium (ZrN), tungsten carbide (WC) different conditions. Results showed propagation were limited extreme when using Design Expert optimization confirmed TiN WC coatings would enhance lifetime inhibit initiations could results severe plastic deformation.
