Infrared Radiation of Plasma-Sprayed Tungsten,Tantalum,and Molybdenum Coatings.

摘要

Infrared radiation properties and characteristics of plasma-sprayed tungsten,tantalum,and molybdenum coating surfaces were investigated in the wavelength region extending from 1.0to 10.0microns and at temperatures of 1000 K and 1600 K. The normal spectral emittances,integrated normal total emittances,and infrared radiation intensity curves of the refractory metal coating surfaces were found. These properties and characteristics were then compared to those which were known for highly polished surfaces of tungsten,tantalum,and molybdenum. (Author)
