Corundum, which is a form of Alumina, is used to manufacture various components and mechanical, electrical and electronics parts. Known for its relatively high hardness, its other characteristics depend on the rate of porosity that varies depending on the manufacturing process. One of the characteristics to consider is the value of the tensile stress in a standard test to failure as a function of the force applied and the rate of porosity. In this study, to analyse the simultaneous effect of two parameters, we used the statistical method of design of experiments. The study and analysis make it possible to establish a response of the effect of the two parameters in isolation from each other, then their effects simultaneously. Consequently, this will allow us to establish a mathematical model by which we can explain the tribological behaviour of porous corundum, with curves and graphs, and optimize the final result.
