Abstract

 

In this study, sliding wear on specimen surfaces subjected to tensile loads was investigated. Specimens were loaded with four tensile loads that correspond to 0, 20, 40 and 60% of the specimens’ yield strength value, and then the resulting variations of wear rate with respect to sliding distance were investigated. In addition, a constant dead load of 60 N was exerted on the specimens and two different values of sliding speed were adjusted at 0.628 and 1.256 m/s throughout the tests. In literature, a similar study was conducted by varying normal loads on specimen whereas in our study, besides the constant normal load on specimen, the effects of sliding speed changes on wear under tensile stresses were taken into consideration too. The results of the tests have shown that the maximum sliding wear occurs at a load that corresponds to 60% of the specimen’s yield strength. Just as the wear increases with stresses, it was also found that an increase in sliding speed leads to increase in wear as well.
