Abstract: A system for measuring a temperature of a rotating workpiece comprises a deposition chamber, a crucible within the deposition chamber, an energy source, a drive system, a temperature sensor, first and second sensor wires, a dynamic electrical connection, and a control system. The crucible is configured to hold a deposition feedstock material. The energy source is configured to evaporate the deposition feedstock material. The drive system is configured to rotate the workpiece such that the evaporated deposition feedstock material can impinge the rotating workpiece. The temperature sensor is configured to sense the temperature of the rotating workpiece. The first and second sensor wires are electrically connected to the temperature sensor. The dynamic electrical connection is configured to electrically communicate the signal indicative of the sensed temperature from the rotatable workpiece holder to the stationary portion. The control system is configured to measure the temperature of the workpiece during rotation.

Abstract: A method includes forming a multi-layered ceramic barrier coating under a chamber pressure of greater than 1 Pascals. In the method, low- and high-dopant ceramic materials are evaporated using input evaporating energies that fall, respectively, above and below a threshold for depositing the materials in a columnar microstructure (low-dopant) and in a branched columnar microstructure (high-dopant).
