Claim 11:
12. A method of providing a protective titanium layer to an aluminum component, the method comprising:
forming a first titanium-based layer on the component, wherein the first titanium-based layer is a bulk metallic glass characterized by an amorphous microstructure, and wherein forming the first titanium-based layer comprises:
depositing titanium alloy powder on an outer surface of the aluminum component; and
pulsing energy directly to titanium alloy powder to melt the titanium alloy powder;

forming a second titanium-based layer on the component, wherein forming the second titanium-based layer comprises:
depositing titanium alloy powder;
pulsing energy directly to titanium alloy powder to melt the titanium alloy powder; and
applying vibrational energy to the component to introduce crystalline phases into the second titanium-based layer.
