Modification of the surface of copper alloys with aluminum in the conditions of self-propagating high-temperature synthesis
The influence of the technological parameters of the SHS process (temperature, holding time and alloying of B, Cr, Ti) on the corrosion resistance of brass with a surface alite layer, which effectively resists β-radiation, was studied. The research was carried out in 30% aqueous solutions of HNO₃, H...

Дослідження проводили в 30% водяних розчинах HNO₃, HCl, H₂SO₄. Алітовані покриття, леговані кремнієм, які отримані при оптимальних параметрах, мають у 1,7–2,1 рази вищу корозійну стійкість, ніж леговані B та Ti. Алітовані покриття мають фази: CuSi, CuAl, CuAl₂, CuTi, Ti₂Cu₃, CuCr, Cu₃Al, Cu₂Al, Al₃Si та α-фазу, леговану Cr, Al, Si, B, Ti. При випробуванні у 30% водному розчині HNO3 покриття, леговані титаном та кремнієм, мають втрату ваги відповідно 32 та 37 г/м². 2023 Article Modification of the surface of copper alloys with aluminum in the conditions of self-propagating high-temperature synthesis / B.
