Abstract
Nickel-coated cast iron was laser treated using pulsed excimer radiati on. The amount of processing was varied by varying the laser power den sity, number of pulses per step and the overlap between consecutive st eps. Mixing of the coating and substrate elements was observed. The su rface roughness was a non-linear function of the laser pulse number. S urface layers presented higher microhardness as compared with the untr eated material. The corrosion resistance of the laser-treated material was found to be a function of the number of laser pulses. (C) 1998 El sevier Science S.A.
