The claimed subject matter
The independent claims on appeal read as follows:
1. A method of treating an outer surface of a component comprising the
steps of:
(1) providing a component in a shot peening chamber;
(2) providing shot peening particles having an outer surface including a
sacrificial metal coating selected to provide sacrificial metal corrosion resistance
to said component; and
(3) directing said shot peening particles against said component, and
depositing said sacrificial metal coating on an outer surface of said component.
16. A method of treating an outer surface of a component comprising the
steps of
(1) providing a component in a shot peening chamber;
(2) providing shot peening particles having an outer surface including a
sacrificial metal coating selected to provide sacrificial metal corrosion resistance
to said component; [and]
(3) directing said shot peening particles against said component at a
velocity to indent an outer surface of said component, and deposit said sacrificial
metal coating on an outer surface of said component.
