Abstract

Grey cast iron is employed under chemically and physically harsh conditions. Laser hardening is used to improve the material mechanical properties. The corrosion behaviour of laser hardened cast iron, however, needs to be studied in detail. This study is focused on the assessment of the hardness and corrosion resistance of the laser hardened grey cast iron. Laser hardening was conducted with a continuous-wave (CW) near infrared fibre laser. The corrosion evaluations were carried out with electrochemical analysis techniques. The laser hardened samples with 25 % scan overlap exhibited higher corrosion resistance and hardness than the as-received grey cast iron specimens.
