Abstract

Some applications of diamond infrared windows will require protective optical coatings which not only boost IR transmittance but also protect the diamond surface from oxidation, as diamond surfaces are observed to oxidize in air above 700 degree(s)C. Three different concepts of protective optical coatings on diamond were evaluated using a calibrated plasma heating source, to determine how well they protect diamond surfaces from oxidation at high temperatures. Two of the three coating designs protected diamond surfaces from oxidation to peak temperatures exceeding 1300 degree(s)C, and to temperatures exceeding 800 degree(s)C for periods up to 10s. Microscopic examination of the films shows that the coatings underwent some degree of morphological change, but afforded diamond excellent oxidation protection nonetheless.
