If the bonded junctions are stronger than one of the solids, wear arises from a shearing process within the solid. Fatigue wear is the result of...

Historically, polymer wear has been studied based on the prevailing wear mechanisms at the contact zone (between the polymer surface and a hard counterface), which led to several methods of classification. The classification of...

.... The carbonitriding treatment is used for components exposed to lighter loads and subjected to wear as well as bending ( Ref 8 – 10 ). For those components, which are subjected to contact fatigue during service, the case depths are designed deeper. For the present series of tests, a case depth of 0.7...

Stresses generated by contact between two surfaces characteristically display a maximum component of shear stress beneath the surface. For sufficiently high levels of contact stress, this can result in...

Steel parts subjected to wear conditions are often carburized or nitrided to harden the surface for greater wear resistance. Since both of these processes also introduce residual compressive stresses on the...
