Structure and phase composition of wear-resistant coatings of the TiB2-Al system prepared by electroexplosion sputtering

摘要

The surface profile, structural features, and phase composition of coatings of the TiB2-Al system, which were fabricated by electroexplosion sputtering, are investigated by optical interferometry, scanning electron microscopy, and X-ray phase analysis. It is established that posttreatment surface roughness parameter R (a) = 2.0 mu m. The phase composition of formed layers includes Al, TiB2, and TiBC3. Coatings have a cohesion-adhesion bond with the surface-contact material.
