Summary:Title screen
The paper shows the efficacy of eutectic Nickel coatings for protecting welded joints of steels against corrosion. It increases with increasing content of the eutectic and chemical compounds at the grain boundaries γ-solid solution based on Nickel. Refinement of the structure of the coatings and reduce their heterogeneity allows to increase the protective properties and durability of welded joints against corrosion. It is established that the probability of formation of cracks in the coatings increases with their thickness, intensity of heating and cooling after reflow, and also with increasing content of the eutectic and chemical compounds at the grain boundaries γ-solid solution based on Nickel. Shown to prevent the formation of cracks in the coatings when they are melt you can use optimal modes of heating and cooling of the composition. Modification of the structure of the coatings by grinding them and reducing heterogeneity allows to improve the resistance to crack formation and protective properties of welded joints.
