Formation of large diamond crystals in oxyacetylene flame chemical vapour deposition | Semantic Scholar
Diamond coatings were deposited on diamond-polished molybdenum substrates from a premixed oxyacetylene flame for a long time (up to 4 h) at substrate temperatures between 700 and 950°C, acetylene-to-oxygen ratios 1.02–1.07 and total flow rates between 230 and 310 standard Lh−1. The coatings...
