Abstract:
Specimens steel 1060 were pack aluminized at 760, 830 and 900°C in order to provide a rich aluminium coating and were used as work electrodes, tungsten wire was used as reference electrode and counter electrode also. The dissolution rate was determinate at 884°C in melt salt Na2SO4 using the polarization resistance technique. The aluminium film offers an excellent resistance to the oxidation reaction, although it corresponds to the accelerate dissolution, which was compared to the steel without aluminized. The experimental determination for four prepared series (steel pack aluminized at 760,830,900°C and without aluminized) showed a reasonable anodic dissolution decrease to the specimen pack aluminized at 900°C, due the relationship that exist between the temperature of aluminizing process and thickness film formed on metallic surface.
