| Abstract | Al2O3, Al2O3/Al and Al2O3-Al graded coatings were fabricated on China low activation martensitic steel and silicon substrates by RF magnetron sputtering. The coating composition and cross-section morphologies were investigated using X-ray photoelectron spectroscopy, Auger electron spectroscopy and field-emission scanning electron microscopy. The mechanical properties of the coatings were studied using nanoindentation, wafer-curvature measurements and microscratch tests. The results show that usable Al2O3-Al graded coatings could be fabricated. With a more continuous compositional gradient, the interface zone was more compact. The hardness and elastic modulus of Al2O3-Al graded coatings were less than those of Al2O3 coatings, but greater than those of Al2O3/Al coatings. After annealing at 773 K for 3 h, the hardness of Al2O3-Al graded coating showed a small increase. The residual stresses in Al2O3-Al graded coatings declined to about 0.3 GPa, compared with the 6.6 GPa for Al2O3 coating. The adhesion of Al2O3 was improved by deposition of Al or Al compositional gradient oxide layers. Copyright (C) 2011 John Wiley & Sons, Ltd. |
