Sol-gel boehmite coating has been applied on mild steel substrate and sintered in inert (nitrogen) and oxygen atmospheres at 400°C to obtain a crack-free and dense alumina coating. Thereafter, its corrosion and wear resistance properties were evaluated under different exposure conditions. Fourier transform infrared (FTIR) analysis of the boehmite gel sintered in the above-mentioned atmospheres identified the presence of residual organic precursors in the gel. Microstructure and phase analyses of the sol-gel-coated surfaces were carried out using scanning electron microscopy (SEM) and x-ray diffraction (XRD) analyses, respectively. XRD analysis confirms the presence of alumina phase on the sol-gel-coated surfaces. Traces of organic groups in the gel sintered at 400°C in both of the atmospheres were noticed by FTIR analysis. Sol-gel-coated specimens sintered in a nitrogen atmosphere have shown a somewhat better corrosion resistance in 3.5% sodium chloride (NaCl) as compared to specimens sintered in an oxygen atmosphere. Similarly, an improved wear resistance was measured for the sol-gel-coated specimens sintered in the nitrogen atmosphere.
