| Abstract |
Effects of boron content on electrochemical properties of the bulk amorphous alloys Fe(73.8-x)C(7.0)Si(3.5)BxP(9.6)Cr(2.1)Mo(2.0)Al(2.0)(X = 3, 5, 7) that can be fabricated using hot metal and industrial raw materials have been investigated in the 3.5% NaCl solution, IN H2SO4 solution and IN HCl solution. Bulk amorphous alloys tend to readily passivated in the solutions exhibiting wide passive regions and low passive current densities. The increase of Boron content improves the corrosion resistance of bulk amorphous alloys in the IN HCl solution. The origin of improvement of corrosion resistance of these alloys is attributed to the formation of Cr-rich passive film. |
