IMPROVED COATINGS FROM ORGANOMETALLIC SOLUTIONS.
Abstract
Research was continued with the object of applying a known method of obtaining thin films by organometallic solution decomposition, to new materials of interest for environmental protection and temperature control. The thickness of the films is in the range of 500 Angstroms to four microns. Nickel films, free of impurities, have been obtained reproducibly. Aluminum and chromium films have been obtained, together with carbon, and neither varied firing cycles nor potential catalysts proved effective in preventing formation of carbon. Nickel aluminide intermetallics have been obtained together with other phases; the reason for this non-homogeneity has been found. Two forms of chromium carbide, Cr23C6 and Cr7C3 have been obtained substantially free of other phases. Materials commonly used as anti-reflection coatings (MgF2,La2O3,CeO2) have been applied on glass by thermal decomposition of organic solutions at 500 C in air. A non-destructive technique for predicting final film thickness by measurement of the unfired film is described. (Author)
