摘要: The cascade arc assisted chemical vapor deposition (CACVD) reactor is capable of producing high-quality diamond coatings to accommodate high-volume production. This has demonstrated the ability deposit polycrystalline with high uniformity and industrial-scale productivity. Precise control plasma parameters as well thermal management substrates allows for optimization coating on different materials having various geometries. Approximately 1000 cylindrical 2 mm diameter×20 long can be mounted coated simultaneously in industrial tubular CACVD 1-m-long reaction zone. properties were studied by electron microscopy Raman spectroscopy. influence predeposition treatments was investigated. A comparison characteristics films deposited carbide, Mo, W stainless steel also presented. correlation between morphology CVD vs. substrate material its position chamber assessed using micro-Raman spectroscopy secondary microscopy. There no indication suggest relationship properties.
