New Material Development for Surface Layer and Surface Technology in Tribology Science to Improve Energy Efficiency

摘要

This paper reviews the development of new material and surface technology in tribology and its contribution toenergy efficiency. Two examples of the economic benefits, resulted from the optimum tribology in the transportationsector and the manufacturing industry are discussed. The new materials are proposed to modify the surface property bylaminating the bulk material with thin layer/coating. Under a suitable condition, the thin layer on a surface can provide acombination of good wear, a low friction and corrosion resistance for the mechanical components. The innovation inlayer technology results molybdenum disulfide (MoS_2), diamond like carbon (DLC), cubic boron nitride (CBN) anddiamond which perform satisfactory outcome. The application of the metallic coatings to carbon fibre reinforced polymermatrix composites (CFRP) has the capacity to provide considerable weight and power savings for many engineeringcomponents. The green material for lubricant and additives such as the use of sunflower oil which possesses goodoxidation resistance and the use of mallee leaves as bio-degradable solvent are used to answer the demand of theenvironmentally friendly material with good performance. The tribology research implementation for energy efficiencyalso touches the simple things around us such as: erasing the laser-print in a paper with different abrasion, techniques. Forthe technology in the engineering surface, the consideration for generating the suitable surface of the components inrunning-in period has been discussed in order to prolong the components life and reduce the machine downtime. Theconclusion, tribology can result in reducing manufacturing time, reducing the maintenance requirements, prolonging theservice interval, improving durability, reliability and mechanical components life, and reducing harmful exhaust emissionand waste. All of these advantages will increase the energy efficiency and the economic benefits.
