Available in PDF, EPUB and Kindle. Book excerpt: The use of pulsed excimer lasers, operating at UV wavelengths, for surface modification has many potential applications in the tribology of metals and ceramics. Alterations of surface chemistry and microstructure are possible on standard engineering materials. We have demonstrated improved tribological performance in stainless steel by the formation of a unique oxide and by Ti mixing and in SiC by Ti mixing. Specifically, we have observed reduced friction in dry sliding conditions and a change in the wear process resulting in greatly reduced surface damage. We have also demonstrated the effectiveness of excimer laser mixing in other systems with potential tribological applications. 22 refs., 7 figs.
