|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 at773K for3h, the hardness of Al2O3-Al graded coating showed a small increase. The residual stresses in Al2O3-Al graded coatings declined to about0.3GPa, compared with the6.6GPa for Al2O3 coating. The adhesion of Al2O3 was improved by deposition of Al or Al compositional gradient oxide layers.?2011 John Wiley& Sons, Ltd.|
