Abstract
In this work, the design of the experiment was used to study the influences of temperature, applied load, and sliding speed on the specific wear rate (SWR) of AISI 304 under a dry sliding pin on a disc experiment. It is found that the experimental SWR increased with the increase of temperature and sliding speed up to a certain value and then decreased significantly. It varied linearly with the applied load. In addition, the morphology of the worn surfaces was illustrated by scanning electron microscope (SEM) and the prospect of oxide layer formation due to friction and heat was inspected by x-ray diffraction (XRD). Furthermore, response surface methodology and analysis of variance were applied to test the significance of the variables and the acceptability of the nonlinear created model. Finally, a reasonable agreement was found between the experimental results of previous work and predicted modeling results with an average variation of 11%.
