International Advanced Centre for Powder Metallurgy & New Materials (ARCI) developed ultrafast laser surface texturing technology. The technology can improve the fuel efficiency of internal combustion engines.
♦ Laser surface micro-texturing offers precise control of the size and shape.
♦ The density of micro-surface texture features gains momentum as a way to control friction and wear.
♦ The special feature of the technology is a pulsating laser beam creates micro-dimples or grooves on the surface of materials in a very controlled manner.
♦ The texture traps wear debris when operating under dry sliding conditions. It provides effects like enhancing oil supply that can lower friction coefficients and may enable reduced wear rate. This will improve the fuel efficiency of internal combustion engines.
