VAMAS second round robin on wear test methods

    Research output: Book/ReportReport

    Abstract

    The aim of the present investigation was to produce results from unlubricated pin-on-disc wear tests for the Versailles project on advanced materials and standards (VAMAS) - second round robin on wear test methods. VAMAS is an international project with the aim of simplifying the introduction of new materials. The round robin conclusions will be published in full by the Federal Institute for Materials Research and Testing (BAM) in the journal of Wear and in the VAMAS Bulletin and possibly also in other journals. In the tests performed at the Technical Research Centre of Finland (VTT), the stabile dynamic coefficient of friction for the five combinations of alumina, silicon nitride and steel lay in the range my = 0.48-0.74. Wear occurred as material degradation of five of the ten sliding surfaces, the rates lying in the range 1.4-11 *10-15 m3/Nm. Layer formation (negative wear) occurred on one surface at a rate of -9.7 *10 15 m3/Nm. The standard deviation for results from three individual tests with the same material combination was in the range + 1.4-3.0 % for the coefficient of friction and in the range + 0.70 0.46 % for the wear rate. The tribological behaviour of the sliding pairs was influenced by chemical interaction between the surfaces and by their oxidation.
