    Significant improvement in load capacity, wear resistance, friction coefficient etc. of mechanical components can be obtained by forming regular micro-surface structure in the form of micro-pores on their surfaces. A feasibility study was performed experimentally using Laser Surface Texturing (LST) technique to produce the micro-pores that can serve either as micro-bearings in cases of full lubrication or as micro-reservoirs for lubricant in cases of starved lubrication conditions. In all cases friction is reduced, wear resistance is increased and life is prolonged.
