Abstract
The analysis of the wear resistance of engine components must take into account the whole system. It is of no use to improve the properties of one of the components if it will cause higher wear on the other components of the tribological system.
This paper presents a study to improve the wear resistance of piston ring coatings and liner materials at the same time that the compatibility between their wear rates is focused. The diesel engine tests were run with high sulfur fuel (about 0.9 wt%) and lubricant with low total base number (TBN) with the objective of increasing the corrosive conditions.
The results show that the best compatibility between the wear rates of the top rings and liners is achieved when the rings are coated by plasma spraying with a molybdenum based material containing approximately 15% of moly carbide and when the liners are made of pearlitic gray cast iron with niobium, vanadium and titanium additions.
