3.4 - Local Analysis of Honed Surface in Microscopic Images

L. Wang & F. Puente León
The honed surface of cylinder liners plays an essential role for oil consumption and longevity of combustion engines. The presence of two bands of honing grooves is intended and desired in the manufacturing processes, as they improve the lubrication between the cylinder wall and the piston. Due to the imperfectness of the metal working, honing grooves are smeared and interrupted by the folded metal. These undesired material defects increase the frictional losses and accelerate the...
