Abstract
Adhesion of diamond coatings formed by chemical vapor deposition to substrates, particularly molybdenum substrates, is improved by employing an auxiliary substrate comprising elemental or chemically combined silicon, from which a silane is believed to diffuse to the principal substrate, where it is reduced to silicon and deposits thereon.
