The article presents considerations regarding the cooperation of the piston-cylinder-piston ring (P-C-R) assembly in terms of improving tribological properties.Tribological models are presented, illustrating the interaction of the ring-liner assembly based on traditional mechanical treatment (honing) and modern laser treatment. Using laser ablation micro-machining, the surface layer of the cylinder liner was textured, creating characteristic oil micro-reservoirs. Preliminary results of our own research regarding surface layer texturing are presented.
Preliminary studies aimed at improving the tribological properties of the (P-C-R) assembly included: selection of the best laser micro-machining parameters, surface topography studies, hardness, and chemical composition in micro-areas.
TEXTURING OF THE CYLINDER BEARING SURFACE WITH THE APPLICATION OF LASER ABLATION MICRO-TREAMENT
This paper presents piston – brush – piston rings association interaction (TPC) in the aspect of tribological characteristics improvement. Tribological models showing piston – brush association interaction, which are based on traditional mechanical treatment (honing process) and modern laser treatment are presented. (…)
