A factorial design approach technique was adopted to understand the high stress abrasive behaviour of a diamond reinforced composite coating for various compositions at different loads and abrasive sizes. A linear regression equation was developed and used for understanding the influence of the diamond concentration, applied load, and abrasive sizes on the wear response. A negative value of the coefficient associated with diamond concentration, together with its interactions with the applied load; suggest that the wear rate decreases with increasing diamond concentration. By contrast, a positive coefficient suggests an increase in wear rate due to an increase in related factors such as the applied load and abrasive size. The coefficients associated with the interactions of the parameters are insignificant by comparison with the individual parameters, thereby demonstrating that the interaction effect of these parameters towards the wear rate is insignificant. The wear rate may be extracted in terms of the diamond concentration, the applied load and the abrasive grit size using the above linear regression equation.
