| Abstract | By using a single-pass pendulum impact scratch tester to study wear behavior of several commercial materials, some developments have been made for this testing technique. From the results, four criteria, i.e. specific energy e(=E/V), tangential dynamic hardness H-T(=F-T/A(T)), normal dynamic hardness H-N(=F-N/A(N)) and the scratching friction coefficient mu(=F-T/F-N), were obtained, where the specific energy and the tangential dynamic hardness presented a good linear relationship and were adopted as two equivalent measures of abrasion resistance of a material in single-pass pendulum scratching. The normal dynamic hardness H,corresponded well with the microhardness H-V, and could present wear properties of a material in abrasive wear with a steady load, instead of the microhardness. By comparison of single-pass pendulum scratching with sliding abrasion and sand-blasting erosion tests, it is found that the single-pass pendulum scratching is a form of impact abrasion between sliding abrasion and sand-blasting erosion, and more similar to the sand-blasting erosion with a low impingement angle. |
