چکیده انگلیسی
The experiments were carried out using an Optimol SRV5 oscillating wear tester under lubrication. Specimens were cut from gray cast iron cylinder liners honed and/or plateau honed with diamond or ceramic stones. Counter-specimens were cut from chromium-coated compression ring. Short time tests of 30â¯min duration were conducted at a temperature of â20â¯Â°C, with a stroke of 3â¯mm. In addition, for a few sliding assemblies, durations of tests at the low temperature were extended to 24â¯h. For comparison, similar tests for a smaller number of sliding pairs were carried out at a temperature of 80â¯Â°C. Before and after tests cylinder liner surface topographies were measured by a white light interferometer Talysurf CCI Lite. It was found that the changes of liner height and frictional resistance at the low temperature were smaller from those tested at the elevated temperature. Two-process textures tested at the low temperature led to a smaller final coefficient of friction, compared to one-process surfaces; opposed results were obtained at the high temperature.
