摘要
Al-30 at% Mo alloy films, of excellent adherence, compositional and thickness uniformity have been sputter-deposited on to electropolished and anodized aluminium substrates. Anodic oxidation of the amorphous alloy films results in anodic oxide which is free from molybdenum species in the outer regions and enriched in molybdenum species in the inner regions. The development of the film can be readily interpreted from current knowledge of the mobilities of aluminium, oxygen/hydroxyl and molybdenum species gained from anodizing of relatively pure aluminium in molybdate solution. However, unlike the previous situation which leads to relatively low levels of incorporated molybdate species, significant incorporation results from alloy oxidation which influences markedly anodic oxide resistivity and field strength during anodic oxidation.
