Abstract: This paper presents the effects of surface coating on the wearing resistance of cold forging tools used for manufacturing fixing parts. The wear of test specimens was analysed with and without coating. The titanium carbonitride, titanium nitride and chrome nitride coating were obtained by Physical Vapour Deposition. The coatings were also tested for two different kinds of tools: a trimming die and an extrusion die used in manufacture of fixing parts. The wearing behaviour was observed at industrial scale during the manufacturing process. The best wearing resistance was found for titanium carbonitride coating in both laboratory and industrial scale.
