International Advanced Centre for Powder Metallurgy & New Materials (ARCI) has developed ultrafast laser surface texturing technology, which can improve the fuel efficiency of internal combustion engines.
Laser surface micro-texturing, which offers precise control of the size, shape and density of micro-surface texture features has gained momentum as a way to control friction and wear.
In this technology, a pulsating laser beam creates micro-dimples or grooves on the surface of materials in a very controlled manner.
Such textures can trap wear debris when operating under dry sliding conditions and sometimes provide effects like enhancing oil supply (lubricant reservoir) which can lower friction coefficients and may enable reduced wear rate.
