Reciprocating dry sliding friction tests performed on diamond-coated tungsten substrates produced changes in the surface morphology. A right-cylinder-on-flat geometry was used for the tribotesting. The morphological changes were investigated with sca

Preliminary solid particle erosion testing of 10 μm thick diamond films on silicon substrates showed excellent erosion resistance. The application of diamond coatings to materials that are commonly used in erosive environments should result in signi

Sputtered Ni–TiB2 coatings have been shown to protect Ti–6Al–4V and Inconel 718 substrates from solid particle erosion. However, before new erosion resistant coatings can be efficiently designed, it is essential that the role of mechanical prop

The tribological behavior of dilute solid solution Cu-Al alloys in sliding contact with sapphire and D2 steel was investigated. The worn and unworn contacting surfaces and wear debris were characterized using an appropriate combination of X-ray diffr

Ion bombardment has been used for several years to improve the adhesion of metallic films to ceramic substrates. Many studies have demonstrated such an improvement in film adhesion but no single mechanism is considered responsible. This paper discuss

From a fundamental viewpoint, adhesive wear must be related to the cohesive strengths of the contacting materials and the adhesive strength of the interface. These quantities are related to the electronic structures of the specific atomic species inv

The effects of friction and wear were examined on plasma enhanced chemical vapor deposition (PECVD) diamond films deposited on tungsten substrates. The tribology of diamond on diamond was studied and the changes in surface roughness and the bearing r
