The aims of this study are to examine the effect of metallic coat-ings on reinforcement from the perspective of the durabilityproperties of concrete structures. Also, consider the importance oflaboratory production of cover while investigating how it can beapplied to steel. In this research, to increase the corrosion resist-ance of the structural steel, the reinforcements were coated withthin films with a system called thermionic vacuum arc (TVA). As aresult of recent studies, it has been observed that such thin filmsprotect the reinforcement from corrosion. In this study, the effectof coated reinforcement on corrosion, which is one of the mostimportant structural defects, was investigated. The applied coat-ings are nano-sized and protect the structural steel against corro-sion reactions occurring on the surface. Moreover, these coatingsincrease the adherence between concrete and reinforcement. Specifically, for this study, silver (Ag) was used as a coating com-ponent. After the coating process was completed, the reinforce-ments were placed in cylindrical concrete samples and theirresistance to corrosion was measured with the help of the accel-erated corrosion technique. The results show that the rebarscoated with the TVA system was prolonged the damage occur-rence time (first crack) and diminished the corrosion reactionsthat occurred on the reinforcement surface.
