Since the advent of tribology, conflicting fundamental laws regarding the relationship that exists between friction and contact area in dry sliding condition have existed. For example, during the late 1400’s, Leonardo da Vinci found that the friction that exists between two surfaces cannot be influenced by its area of contact. By 1699, scientists like Amontons remained in agreeance with da Vinci’s explanation.

High-temperature tribology is of particular importance in industries where operational efficiency is affected by the exposure of materials and tribological interfaces to elevated temperatures. Various factors like elastic modulus, thermal conductivity, hardness, thermo-mechanical fatigue, diffusion, grain structure and oxidation can largely influence friction and wear at high temperatures, thus making it a multicomponent problem.

Tribology in MiningAn example of friction and wear process during extraction, materials handling, and material processing is shown in Figure 1. Damages to the materials used for drilling or digging are a result of impact, erosive and abrasive contact with the earth surface. Materials used in crushers are faced with severe impact and abrasive contact with the large chunks of minerals. Mining trucks with lubricated engine components and other power transmission systems, used for materials handling are subjected to lubricated wear. In cases, where the size of the particles is in few mm, the transportation of minerals is made ...

Solid particles in dusty environments can damage materials and affect dimensional tolerances in variety of industries ranging from gas turbines, helicopter rotor system (aerospace applications), boiler tubes (coal power plants) and wind turbines (renewable energy). Erosion of certain components can reduce operational efficiency of systems and have economic impact.
