WC based coatings with high alloy binders were investigated with respect to structure, corrosion and wear. The coatings were made by HVOF spraying of different powders. All powders studied were made by agglomeration/sintering, i.e. agglomeration of metal particles with WC particles with subsequent sintering. Some powders were made using pre-alloyed metal particles. A blend of ceramicmetallic powder and pure metallic powder was also studied. Different methods were used for
characterisation of the powders and coatings.
