Abstract
A method for coating and an associated assembly including such a coating are provided. The assembly includes a workpiece defining a weld portion, such as a friction weld joint and a heat affected zone. A coating is disposed on the weld portion to at least partially cover the weld portion, thereby providing enhanced corrosion resistance to the workpiece.
Claims19
A method for providing a corrosion resistant coating on a workpiece, the method comprising:
- providing a workpiece defining a weld portion by friction welding the workpiece to form the weld portion;
- and
- subsequently depositing particles of an aluminum material onto the weld portion of the workpiece to thereby form a coating of the aluminum material on the weld portion of the workpiece.
A method for providing a corrosion resistant coating on a workpiece, the method comprising:
- depositing particles of an aluminum material onto at least a first surface of the workpiece by spraying the particles onto the first surface to thereby form a coating of the aluminum material on the first surface of the workpiece;
- and
- friction stir welding at least a portion of the first surface of the workpiece after said depositing step to thereby form a weld portion.
