Cylinder liner; Two-process surfaces; Coefficient of friction
The experiments were conducted using an oscillating wear tester under lubricated conditions. Specimens were cut from cylinder liners made of gray cast iron. As the results of honing and/or plateau honing various surface textures of cylinder liners were obtained. Counter-specimens were cut from chromium-coated compression ring. Short time tests were carried out at temperature of 80 degrees C, stroke was 3 mm. The other operating parameters, like normal load and frequency varied. Before and after tests surface topographies of liners were measured by a white light interferometer. It was found that one-process textures led to smaller coefficients of friction than two process topographies for test duration of 0.5 h. The frictional resistance increased when honing angle increased.
