Wear Evaluation and Ranking of Tribomaterials Using a Hasse Diagram Approach

Abstract

A procedure is developed to evaluate and rank tribomaterials based on wear parameters using a vectorial approach. The method known as the Hasse Diagram approach allows one to graphically compare tribomaterials based on a large number of wear parameters or test results which might otherwise be very confusing. The inclusion of uncertainty and a provision to include weighting factors so that the ranking scheme does not change when additional tribomaterials are added have also been discussed. An example of eight tribomaterials has been presented for ranking based on five wear parameters.
