Surface Modification Technologies XV presents the reviewed and edited proceedings of the SMT conference held in November 2001 in Indianapolis, USA. The proceedings describe state-of-the-art surface engineering work in thermal spray, wear-resistant coatings, surface characterization, scanning probe techniques, surface treatment for corrosion and joining, and cadmium and chromium replacement. Contents include: thermally sprayed materials; wear resistant coatings; characterization of industrial surfaces with scanning probe-based techniques; surface treatments for corrosion and joining; processing of coatings; characterization of coatings; replacement of cadmium/chromium.
