... fracture toughness measurements. The abrasive wear resistance was determined using the ASTM G65-04 dry-sand rubber wheel test. The results showed that the hardness of the near-nanocrystalline coating was 25% greater than that of the microcrystalline coating and a sixfold increase in the abrasive wear...

... between the shape memory effect and the wear behavior of the NiTi alloy. They show that as the shape memory effect of the alloy decreased with increasing temperature, the wear of the alloy decreased. On the other hand, Liang et al. ( 8 ) concluded that the wear resistance of a NiTi alloy increases...

... fibrils and hydroxyapatite. Enamel is hard, brittle, and wear resistant, while dentine is softer and flexible. The dentine-enamel junction is formed as a region at which enamel mixes with dentine in a continuous way. The nanomechanical properties of the transition zone have been recently revealed...

... surface strength while it is brittle and wear resistant, whereas the inner part is softer and flexible. The specific variation in Young’s modulus along the thickness of the presented composite is of particular interest in our case. The present work presents a finite element analysis and an experimental...

...D. S. Li; H. Garmestani; S. Ahzi; M. Khaleel; D. Ruch A microstructure design framework for multiscale modeling of wear resistance in bioimplant materials is presented here. The increase in service lifetime of arthroplasty depends on whether we can predict wear resistance and microstructure...

... used these days to dramatically improve the wear resistance of composites, even up to three orders of magnitude ( 8 ). Various kinds of polymers and polymer matrix composites reinforced with ceramic powders have been the subject of extensive research in past 2 decades. The inclusion of such particulate...

...Ping Huang; Rong Liu; Xijia Wu; Matthew X. Yao The chemical composition of Stellite ® 21 alloy was modified by doubling the molybdenum (Mo) content for enhanced corrosion and wear resistance. The specimens were fabricated using a casting technique. Half of the specimens experienced a heat treatment...

...Xin Lei; Cliff J. Lissenden Discontinuously reinforced aluminum (DRA) is currently used where design considerations include specific stiffness, tailorable coefficient of thermal expansion, or wear resistance. Plastic deformation plays a role in failures due to low cycle fatigue or simple ductile...

... method (ASTM standard E837) with an EDM drilling process provides the effective means of determining the residual stress in materials with high hardness and good wear resistance. tool steel carbon steel internal stresses electrical discharge machining drilling cold working hot working thermal...

...Rong Liu; Matthew X. Yao; Xijia Wu Two cobalt-based superalloys containing 1.6% and 2% carbon respectively were studied, with the emphasis on the influence of the carbon content on their microstructures, wear resistance, and mechanical properties. Phase formation and transformation...
