USE OF ELECTRIC ARC METALLIZATION TO PROTECT METAL SURFACES FROM CORROSION: A STUDY ON THE EXAMPLE OF STEEL 45 AND 30HGSA WIRE

The effect of protective coating applied to steel 45 made of 30HGSA wire by electric arc metallization on corrosion resistance compared to untreated steel 45 was investigated. The test methodology included electrochemical analyses such as polarization curves. The results showed that steel 45 coated with 30HGSA wire shows significantly higher corrosion resistance compared to standard steel 45. The result of this study confirms the significance of electric arc metallization technology as an effective way to improve the corrosion resistance of steels. The application of protective coating of 30HGSA wire on steel 45 not only improves its characteristics, but also provides opportunities for more durable use in aggressive environments. Also, these methods can be adapted for other types of materials, which opens new perspectives in the field of steel structures protection. This research can serve as a basis for the development of new norms and standards in metal fabrication and processing. These results provide valuable scientific data that can contribute to the development of improved corrosion resistant materials for applications in critical industries such as oil and gas, marine and construction projects, and mechanical engineering, where material reliability is a key factor.
