Özet

Corrosion results cracking in the concrete and it reduces the bearing capacity. Corrosion affects the durability of rebar; therefore, usage would not be economical and complete its lifetime if this situation persists. Iron and steel materials lose their physical, chemical and electrical properties by being affected by these different atmospheric conditions. In this study, the corrosion resistance of reinforcement in concrete structures was increased. For this purpose, the reinforcements are coated with combinations of zinc and boron elements by using a different principle, the thermionic vacuum arc system. The coated reinforcements are embedded in the concrete mixture in the mold. After the curing stage, the samples were taken out of the molds and subjected to accelerated corrosion test. The results show that the rebars covered with the TVA system were damaged later than the uncoated rebars. Thanks to the coatings, the damage occurrence time is extended and the corrosion resistance of the reinforcement is increased. It is believed that with this study, it will contribute to the prolongation of the life of the structures by eliminating the corrosion reactions that occur as a result of negative effects in the reinforcement.
