Magnesium alloys, despite their lightweight properties, have not garnered the attention they deserve in the biomaterials sector due to their low wear and corrosion resistance. Alloys containing tantalum and coated materials are widely used in the implant industry and are frequently studied for their high corrosion resistance and antibacterial properties, making them suitable as biomaterials. In this study, tantalum-containing coatings were applied to the surfaces of ZK60 magnesium alloy, which had undergone various surface treatments, using the cold spray coating technique recently gaining traction in the literature due to its suitability for magnesium and its alloys under low-temperature conditions. The surface morphology, wear, and corrosion resistance of the coatings were evaluated, and the effects of surface treatments were discussed. The results indicated that the sample subjected to sandblasting before the coating process exhibited higher surface roughness, a thicker coating layer, and greater wear resistance compared to samples that underwent acid treatment and polishing. However, the increased roughness led to the accumulation of corrosion currents in localized areas, resulting in decreased corrosion resistance.
