【 摘 要 】

The paper studies the structure and demonstrates the efficiency of application of eutectic nickel coatings for protection of welded joints of the 10G2S-type steels from corrosive action. It increases simultaneously with the increase of eutectic content and chemical compounds along the grain boundaries of the γ-solid solution based on nickel. The refinement of the coatings' structure and the reduction of their heterogeneity allow enhancing the protective properties and resistance of welded joints to corrosion.
