Title Finite Element Simulation of Cracks Propagation in Rolling Contact Applications with and without Coating Applied in industrial Field.
The aim of this study is mainly about preventing crack initiation and propagation in rolling contact under moderate and extreme loading through coating technology using finite element simulation and design optimization techniques. Several applications of rolling contact were conducted and the parameters related to rollers’ materials, coating, temperature, and loads were investigated.
M50 steels (0.8C–4.2Cr–4.3Mo–1V wt. %) and 100CrMnMo8 steel (1.0C–2.0Cr– 0.5Mo–1.0Mn– 0.5Si wt. %) were analyzed with and without titanium nitride (Tin) and tungsten carbide (Wc) coatings under different temperature and loading conditions. Results showed that cracks propagation were limited to extreme load when using coating technology. A three-dimensional finite element model showed the Von Mises stresses and displacement under different temperatures and the finding confirmed that Tin and Wc coatings would enhance the lifetime of rollers and inhibit cracks initiations and plastic deformation. The parameter used in this study correlate closely with previous experiments and provided a solid conclusion of the best combination in rolling contact applications.
Impotent parameters in this field are the principal roller materials, back up roller, coating thickness, coating materials, rolling contact fatigue (RCF) and the temperature parameter.
