Electrochimica Acta, 1989
Abstract In industrial anode processes, the starting materials dissolved in aqueous electrolytes are oxidized at inert anodes. In most cases, metal anodes with an oxidic surface layer are employed. According to their fabrication, chemical, thermal, anodic and ceramic oxide coatings can be distinguished.

Wear Mechanisms in Grinding of PCBN
Advanced Materials Research, 2015PCBN-inserts have a high potential in the cutting of hardened steel, cast iron and super alloys due to their high hardness and heat resistance. Nevertheless they have a high purchase price, which lowers the economic benefits for the end user compared to other cutting materials. This is caused by the high production costs of the inserts. The grinding of

When two solid surfaces are placed together, contact generally occurs only over isolated parts of the nominal contact area (Bhushana in J Vacuum Sci Technol 21(6):2262–2296, 2003). It is through these localised regions of contact that forces are exerted between the two bodies, and it is these forces which are responsible for friction.

Numerical simulation of wear-mechanism maps
Computational Materials Science, 2002Abstract Wear-mechanism maps for different materials, actually steel on steel, are being modeled with FEM. A microthermo-mechanical approach has been used in order to model accurately the macroscopic phenomena of wear. A plastic law for the normal micromechanical contact of asperities has been implemented in FEAP and a slight modification, based on ...

Contact Mechanics: Friction and Wear
1998Contact mechanics describes the stresses and the deformations in the neighbourhood of the contact between two pressed bodies. The following examples are given: concentrated and distributed normal and tangential loads, point load, pressure on a circular surface, hertzian contact for normal and tangential loadings.

Implant wear mechanisms—basic approach
Biomedical Materials, 2008Numerous parameters control the long-term performance of a total hip joint arthroplasty. The articulating motions between the femoral and the acetabular components produce wear debris in a hip implant. Surface roughness, clearance, coefficient of friction and sliding distance are found to be contributing parameters that affect wear rates. Wear produced

Modeling (and) Wear Mechanisms °
2001In all technical fields the highest accomplishment is to formalize knowledge into mathematical (equation) format. This action serves two purposes, namely, a. To provide equations that engineers can use in product design, and, b. To add purpose and discipline to research.

British Journal of Applied Physics, 1958
The design of fundamental experiments for examining the wear phenomena encountered in the conditions of speed and loading of industrial machines is discussed. Apparatus is described in which nominal point or nominal line contact can be maintained indefinitely, and some of the phenomena observed when a lubricant is used are discussed. With carefully run-

The relevance of wear-mechanism maps to mild-oxidational wear [PDF]
Tribology International, 2002 The presence of oxygen in the environment in which a steel sliding system operates will promote a mild form of wear with wear debris consisting mainly of iron oxides. Of the oxidation-dominated mechanisms, mild-oxidational wear (the prefix describes the extent of oxidation and not the wear rate) has been most extensively investigated.

Tool wear mechanisms in machining
International Journal of Machining and Machinability of Materials, 2007Most of tool wear studies are classified as empirical (e.g. Taylor's equation); thus, they do not bring out the physical nature of the wear phenomenon. Consequently, tool life in general cannot be predicted by extending the result from one study. By understanding the physics behind the process, the important wear mechanisms can be identified.
