ABSTRACT: Two alloys were used in order to extend the service life of marine engine exhaust valve head. Layers of cobalt base alloys on the valve faces were produced by laser cladding. After a certain period of service, one of the valves was severely damaged. This research indicated that proper material selection can influence the duration of the service life and operational safety of marine engines.
