Laser drilling methods of shallow-angled holes
Abstract:
A method for drilling a shallow-angled hole through a thermal barrier coated component, in accordance with one aspect thereof, includes a step of applying a pulse laser beam with a first setting to drill a section of the hole substantially within a thermal barrier coating of the component. A further step is conducted to apply the pulse laser beam with a second setting through the initiated hole to further drill through a remainder of the component to complete the formation of the hole extending through the component.
