A Comparative Study of the Tribological Behavior of Tin Powder Clad on the JIS SKD11 Tool Steel with the GTAW Method

Abstract

This work focused on the wear performance of the clad layers which were formed with cladding titanium nitrides (TiN) powder on the JIS SKD11 tool steel by the gas tungsten arc welding (GTAW) method. A rotating type tribometer was used to evaluate the wear behavior of the clad specimens under different sliding conditions. Furthermore, a nanoindenter was used to measure the hardness and elastic modulus of the reinforcements. According to the wear test results, the wear performance of the specimens cladded with TiN powder was better than that of the JIS SKD11 tool steel specimens. During dry sliding wear test, the clad layers exhibited a strong wear resistance because they contained the hard TiN reinforcements. Therefore, the wear performance of the clad layers was substantially better than that of the SKD11 specimens under all the test conditions in this study. In addition, produced oxide films might influence the wear behavior of different specimens during the wear testing, and oxidation wear would even dominate the wear behavior of the clad layers under some conditions.
