Abstract
A process for forming a single crystal superalloy wave spring is provided. In one embodiment, the process may include machining a wave spring from a single crystal superalloy slab after optimizing its orientation using diffraction techniques so that the wave spring will exhibit optimal spring properties.
Claims10
A process for forming a single crystal superalloy wave spring, comprising:
- designing a wave spring;
- placing a single crystal superalloy slab into a sacrificial holder;
- inserting both the single crystal superalloy slab and the sacrificial holder into a multi-axis goniometer;
- using diffraction techniques to determine a proper orientation and alignment of the single crystal superalloy slab while inserted in the goniometer so that the single crystal superalloy wave spring will exhibit optimal spring properties;
- adjusting the goniometer based upon the determined results of the diffraction techniques;
- and
- cutting the designed wave spring from the single crystal superalloy slab as oriented and aligned using the diffraction techniques to form a single crystal superalloy wave spring having optimal spring properties,
- wherein achieving the optimal spring properties comprises optimizing stress relaxation properties, minimizing stresses, and maximizing wave spring deflection capability and resiliency.
