Abstract
The described embodiments relate generally to aluminum films and methods for forming aluminum films. Methods involve providing aluminum films having increased hardness. Methods involve using higher than conventional current densities during plating of aluminum on substrates. The higher current density plating creates aluminum films with grain structures that are different from conventional plated aluminum films. In some embodiments, the average grain sizes are smaller in the hard aluminum films than conventional plated aluminum films. In some embodiments, the plated aluminum layer is anodized. In some embodiments, a multi-layered aluminum coating is formed using a combination of high current density and low current density plating. In some embodiments, a current filter is used to provide uniform plating across a part.
