    摘要： A system for producing at least one trench to improve film cooling in a sample is provided. The system includes at least one laser source outputting at least one pulsed laser beam. The pulsed laser beam includes a pulse duration including a range less than about 50 μs, an energy per pulse having a range less than about 0.1 Joule, and a repetition rate with a range greater than about 1000 Hz. The system also includes a control subsystem coupled to the laser source, the control subsystem configured to synchronize a position of the sample with the pulse duration and energy level in order to selectively remove at least one of a thermal barrier coating, a bondcoat and a substrate metal in the sample to form the at least one trench.

    摘要： A method for bending a tube in a pre-selected geometry includes deriving at least one processing parameter from the geometry, applying a thermal source circumferentially to the tube to heat the tube along at least one circumferentially directed path in accordance with the parameter and actively cooling the tube to a pre-selected temperature. The applying and active cooling steps are alternately performed a number of times. A system for bending the tube includes a thermal source for heating at least one region along the path on the tube, a tube advancing module for advancing the tube, an active cooling module for cooling the tube to a pre-selected temperature, a processing module to derive at least one processing parameter from the geometry and a control module configured to control the thermal source and active cooling module in accordance with the parameter. The alternate heating and cooling are performed a number of times.
