Abstract The need for new materials in various engineering applications are inevitable. The performance measurement ensures the selection of suitable materials for the relevant applications. Corrosion types of failure are gaining attention nowadays, which has shifted the researchers towards developing new materials with enhanced corrosion resistance. In this work, the copper-tin alloy-based hybrid composite was prepared through the powder metallurgy route. The 5 wt% of graphite and 1 wt% of silicon dioxide are used as reinforcement. Further, the corrosion performance of fabricated sample was carried out through two-electrolyte solution. The first one is acidic, i.e. HCl and the second one is salt, i.e. NaCl. It was observed that the electrolyte solution has shown that it is allowing a faster corrosion process and has no side impact on the corrosion profile due to the presence of a passivation layer. A passivation layer is nothing, but it is forming an oxide layer on the surface, which resist the corrosion profile from the side impact.
