Mathematical model for determining the linear wear intensity with consideration of hardness and average pressure to friction surface has been designed. The correctness of method for determining the average pressure to friction surface during the experiment and its influence on the abrasive wear was analyzed. Graph of the linear wear intensity dependence on the average pressure on the friction surface and tested material hardness was plotted. The obtained surface of the linear wear intensity is the geometrical model which allows predicting the material abrasive wear quantity.
