On the estimation of strength properties of porous ceramic coatings
Source abstract
Abstract
A method for estimating the strength properties of a porous ceramic coating was proposed. The method is based on the analysis of preliminary test results on indentation of coatings with defects of varying size and depth of occurrence. The strength properties of the coating were studied by computer simulation combining the discrete description (the movable cellular automata method) and continuous description (the finite difference method). Relationships were found between the parameters of a pore such as its length and depth of occurrence in the coating and the critical stress corresponding to fracture of the coating. The proposed method can be used to study the strength properties of material surface layers and to predict the critical stress in a contact region.
