Carbides change highly effective on the mechanical and tribological properties of the coatings. For this reason, it is very important to determine the carbide ratio in the microstructure correctly. Researchers mostly try to determine phase …

Research Article Open Access Numerical and Analytical Analysis of Hertz Contact Pressure in ASTM G99 Wear Test

Esad Kaya, Kaya E, Koray Kılıçay, Kılıçay K, Mustafa Ulutan, Ulutan M

Ist International Symposium on Innovative Approaches in Scientific Studies 2018

Contact pressure is very critical for wear test. In order to make true wear experiment, counter body, surface, wear load, surface roughness, and the hardness of materials should be selected correctly. Maximum contact pressure forms at hertz…
