简介
The aims of this paper are to examine the effect of metallic coatings to reinforcement on the perspective of the durability properties of concrete structures. Also, considering the importance of laboratory production of cover while investigating how it can be applied to steel. In this research, in order to increase the corrosion resistance of the structural steel, the reinforcements were coated with thin films with a system called thermionic vacuum arc (TVA). As a result of recent studies, it has been observed that such thin films protect the reinforcement from corrosion. In this study, the effect of coated reinforcement on corrosion, which is one of the most important structural defects, was investigated. The applied coatings are nano-sized and protect the structural steel against corrosion reactions occurring on the surface. Moreover, these coatings increase the adherence between concrete and reinforcement. Specifically for this study, silver (Ag) was used as a coating component. After the coating process was completed, the reinforcements were placed in cylindrical concrete samples and their resistance to corrosion was measured with the help of accelerated corrosion technique. The results show that the rebars coated with the TVA system was prolonged the damage occurrence time (first crack) and diminished the corrosion reactions that occurred on the reinforcement surface.
