AbstractHybrid composites are materials that have a combination of two or more reinforcements. These materials have extensive engineering applications that have a low strength/density ratio, low cost and ease of manufacturing. Hybrid composites provide a combination of properties such as tensile modulus, compressive strength and impact resistance, which cannot be realized in composite materials. The surface properties of the materials must be improved against corrosion and wear. It is therefore essential and important that the coating layer has both wear and corrosion resistant phases. In this study, the surface of AISI 316L stainless steel is coated with metal powder having different composition by tungsten inert gas (TIG) welding surface coating method. Ti, B4C and SiC metal powders of different ratios were used as coating powder. The corrosion properties of coated samples were characterized by potentiostatic polarization test. Corrosion test results showed that corrosion properties vary depending on the coating components.
