Abstract :Steel alloys are one of the most used engineering material classes due to their superior properties such as yield and tensile strength, good thermal conductivity, machinability, formability, ductility, magnetic properties, and recyclability. In addition to its advantages, steel suffers from two main factors that limit its use, namely wear and corrosion. Wear and corrosion, separately or in combination, cause a material loss in steel, resulting in increased costs in industrial production. However, with appropriate surface treatments, wear and corrosion of steels can be prevented or kept to a minimum. Corrosion and wear resistances provided by appropriate methods have the potential to reduce costs and also expand the set of suitable materials that designers can choose from. In this study, brief information about steel is given and then preventive applications against wear and corrosion of steel materials are examined. Definitions were made about surface treatments such as hot-dip coatings, electrochemical coatings, electroless coatings, thermochemical surface treatments, sol-gel coatings, chemical vapor deposition (CVD), thermal spray coatings, physical vapor deposition (PVD), and the effects of surface treatments on the wear and corrosion properties of steels were investigated. In addition, the effects of some process parameters of surface treatments and post-treatments such as heat treatment on corrosion and wear behavior are presented.
