Abstract
This study investigates a method of enhancing the corrosion resistance of structural steel through the deposition of surfacing layers containing hafnium and titanium borides via non-vacuum electron beam surfacing (NV-EBS) of powder mixtures. The fabrication of 1.6 mm thick coatings was performed on 12Kh18N9T and 40Kh structural steels. Structural and phase analyses confirmed the presence of HfB2, HfB, and HfTi phases within the coatings. These phases resulted in minimal corrosion rates of 0.05 mg and 0.01 mg after 30 h. This was significantly lower than the corrosion rates of the 12Kh18N9T and 40Kh reference materials, which were 0.25 mg and 0.9 mg after 30 h, respectively. Increasing the hafnium content further reduced the corrosion rate and preserved the coating morphology after exposure to an aggressive medium.
