Abstract

Abstract The study focuses on monitoring influence of the alumina coatings on friction and stability of the microscale iron contacts by the smoothed particle hydrodynamics. The obtained results show a better stability and a higher value of the friction coefficient of the coated surface compared to those of the uncoated one. This study also supposes that in concern of stability of the surface the coating should be done with only the substrate surface accompanied with the roughness of the coating layer. The proportion of the coated particles is found to be strongly resulting in the friction properties, and the roughness of the coating layer also slightly results in those. The surface reaches the most stability at the proportion of around 70%.
