Abstract Scope Marine environment has significantly high risk of corrosion from Cl ions and dissolved oxygen in seawater, accompanied by wear behavior due to waves and sand. When corrosion and wear occur simultaneously, the interaction between chemical and mechanical action brings about early destruction of parts. To minimize these hazards, surface processing such as thermal spray coating is applied in many cases. In this study, low carbon steel has been coated with aluminum by thermal spray process. Al coatings with different Si content (Pure Al, 94Al-6Si, and 88Al-12Si) were investigated. Cyclic potentiodynamic polarization, galvanic corrosion test and immersion test were performed for investigation of corrosion properties. To evaluate the wear properties of corroded coating, wear tests were conducted to as-sprayed and corroded coatings.
