A Friction-Dissipation Based Method for Quantity Model and Prediction of Graphite/WC-Ni Wear under Dry Sliding

In the present work, a linear model for assessing the wear of graphite sliding against WC-Ni under dry condition was developed. This model described the relationship between the wear rate of graphite with the friction dissipation of the graphite/WC-Ni. This model was utilized to predict the graphite wear of both single and combined working conditions, the predict results were in good agreement with the measured results. The model had a clear physical meaning, and was concise, easy use and reliable. The quantitative model for assessing and predicting the wear of tribo-pair was not only theoretical but also practical significant.
