Available in PDF, EPUB and Kindle. Book excerpt: Microwave plasma-enhanced chemical vapor deposition of diamond films on silicon carbide and tungsten carbide (with 6% cobalt) surfaces using fluorocarbon gases has been demonstrated. No diamond powder pre-treatment is necessary to grow these films with a (100) texture. The diamond films are characterized by scanning electron microscopy and Raman spectroscopy. The proposed nucleation and growth mechanism involves concurrent etching of the non- carbon component by atomic fluorine and deposition of diamond. Hydrogen is necessary in the growth process to limit the rapid etching of the substrate by fluorine atoms.
