Abstract
Finding a way to reduce the wear resulted from aperities interactions in mixed
lubrication regime is an interesting area. One of the inspiring solution is
surface texturing. Using a convenient laser, a textured surface with arbitrary
micro cavity shape and size was prepared accurately. In this study, the effect
of laser surface texture on the wear and friction behavior of discs in line and
point contact in mixed lubrication regime was investigated. The effect of
texturing area, linear velocity, and vertical load were examined. The friction
coefficient variation reaches a narrow margin after an adequate distance. The
results showed that wear decreases with increasing speed and decreasing the
applied force. Comparing the results between plane and textured discs, it was
found that the coefficient of friction was reduced between 12 and 19% and the
amount of wear was reduced by almost more than 40%.
