ADDITIVE LAYER REPAIR OF A METALLIC COMPONENT

A method of repairing a metallic component (100) (formed from a first material (110)) by powder feeding laser deposition, comprises the step of depositing a plurality of first repair layers (130) onto a repair surface (120) of the component (100) to form a first repair zone (140), the first of the plurality of first repair layers comprising a mixture of A/B by weight of the first material (110) and a second material (150), each nth successive one of the plurality of first repair layers comprising a change in the proportion of the second material in the mixture, the last of the plurality of first repair layers comprising a mixture of C/D by weight of the first material (110) and the second material (150).
