A method of providing a protective titanium layer to an outer surface of an aluminum component, the method comprising:
- providing an aluminum component;
- forming a first layer of titanium-based bulk metallic glass on the component, wherein formation of the bulk metallic glass layer comprises depositing a titanium alloy powder using pulsed directed energy deposition;
- and
- applying vibrational energy to the component during deposition of a second layer of the titanium alloy powder to introduce crystalline phases into the second layer.
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.
