1. A magnesium component of a rotary wing aircraft comprising:

a groove including a recessed opening located within a central portion of the groove and a first sidewall and a second sidewall arranged on opposing sides of the recessed opening, wherein the first sidewall includes an area from which material of the first sidewall was removed, wherein the area extends to the recessed opening; and

a deposit arranged within the area adjacent the recessed opening, the deposit being integrally formed with the first sidewall by cold spraying one or more layers of powdered material within the area of the first sidewall from which material of the first sidewall was removed, wherein the deposit is substantially identical in size and shape to the area from which material of the first sidewall was removed.

2. The magnesium component according to claim 1 , wherein the magnesium component is a gearbox housing.

3. The magnesium component according to claim 1 , wherein the powdered material includes aluminum.

4. The magnesium component according to claim 1 , wherein damage is expected to occur to the area of the sidewall where the deposit is located.

5. The magnesium component according to claim 1 , wherein the deposit extends from an inner surface of the recessed opening to an outer surface of the sidewall.

6. The magnesium component according to claim 1 , wherein the magnesium component including the deposit has at least one dimension substantially equal to an original dimension of the magnesium component.

7. The magnesium component according to claim 6 , wherein the deposit is substantially flush with a remainder of the sidewall.
