Thermal spraying technologies make part in the current worldwide scene as serviceable and profitable assemblies for a wide range of intents. The stepwise adoption of those techniques by many production settings has driven companies to progressive investments towards the prospective usage of goods in efforts to attend innovative designs and customers needs. Wear resistance is among the desired features by which a forming tool must be able to provide while performing. In this context the tribology plays an important role, where the adoption of suitable materials and operational parameters jointly contribute for an outstanding lifetime. To enhance the tribological behaviour of forming tools thermal spraying technologies have been employed. This work presents a comparison of steel materials coated through arc spraying and atmospheric arc spraying processes. The influence of coating type and carbide size on tribological properties are studied. Corresponding SEM, light microscopy and 3D-surface analyses are conducted to understand the tribological behaviour of different coatings at different loading conditions. |
