An alternative approach to fabrication of thick coatings is thermal spraying. In thermal spraying powders are generally used as the feedstock and fed into a flame aimed at the surface of substrates. The powders are propelled in the gas flow and are fused to form coatings on the substrate. Ther...
Thermocouple 50 is fed through the aligned partial lateral thermocouple bore 44 in the Haynes alloy substrate holder 40, traverse thermocouple bore 22 in the BN main body portion 20 and thermocouple hole 26 in the Haynes alloy retaining disk 25. Thusly disposed, thermocouple 50 provides for the ...
An alternative method is based on the fact that changes in the spectral characteristics of a single-mode laser occur when a portion of the laser output is fed back into the laser cavity. A number of investigators ("Direct Observation of Lorentzian Lineshape of Semiconductor Laser and Linewidth ...
