A new laser surface patterning technique called Laser Interference Metallurgy is used to structure metallic samples, attempting to increase the lubricant film lifetime. Lifetime tests were carried out for several pattern geometries and two laser intensities. In some cases, lifetime improvements were remarkable, up to around 1500 %.
