Abstract:
A pin-on-disk test rig is used to model two body abrasive wear process. The parameters investigated include applied load, system stiffness, surface roughness, sliding speed, and hardness of the test materials. Two-level full factorial design of experiments is used to analyze the effect of these parameters on wear rate, normal force, and friction force. The wear rate is found to be directly proportional to load, system stiffness, sliding speed, and surface roughness. Where as hardness is found to have inverse effect on wear rate. Among the parameters investigated, normal load and hardness have a significant effect on wear rate. Mathematical models for predicting abrasive wear, friction force and normal force are developed. Within the envelope of parameters investigated, the predictor equations are found to approximate the behavior of wear rate, friction force, and normal force with 96%, 98%, and 94% confidence interval, respectively.
