EFFECT OF EXCIMER LASER PRETREATMENT ON DIAMOND FILM DEPOSITED ON HARD ALLOY SUBSTRATE
准分子激光预处理对硬质合金表面沉积金刚石薄膜结合强度的影响

Adhesion strength of diamond film with substrate WC-6% Co (YG6) subjected to different pre-treatments was studied. It was found that the adhesion was greatly increased by excimer laser irradiation pre-treatment. The mechanisms responsible for this adhesion enhancement are due to the selective evaporation of cobalt and, to a larger extent, due to the "anchoring effect" resulted from the surface modification (roughening) by the energetic excimer laser beam.
