The objective of this research was to determine the influence of applying a hybrid treatment, consisting of fine particle bombardment (FPB) and powder impact plating (PIP), on the scuffing behavior of ductile cast iron. Ductile cast iron samples were processed by an FPB treatment, a PIP treatment, and a hybrid treatment of both FPB and PIP. Scuffing behavior of these samples was investigated using...
This study considers two approaches towards increasing the dry scuffing resistance of grey cast iron (CI) cylinder bore (or liner) surfaces, namely by i) decreasing the initial roughness of the CI liner surfaces and ii) by applying a diamond-like carbon (DLC) coating to the top compression piston rings. CI liners were polished to different surface roughness values ranging between 0.08µm and 6.83µm...
The purpose of this work was to investigate the effects of different texture patterns and orientations on the wear and failure mechanisms of grey cast iron sliding against 42CrMo6 steel. Reciprocating tests were performed on 16 different micro-textures under starved lubrication conditions. The textures were designed using a design of experiments (DoE) approach and produced by a nanosecond-laser. Under...
The abrasion wear resistance of white cast irons can be controlled primarily by adjusting the size, size distribution, and volume fraction of the carbide phase. The main physical property of white cast irons correlating with abrasion resistance is hardness. This study concentrates on the evaluation of hardened and stress relieved, normalized, self-hardened, and as-cast states of high chromium white...
