ABSTRACT:
This invention is directed to the creation of diamond coatings with enhanced adherence, nucleation density and uniformity on substrates. The method of this invention includes the formation of a carbide layer on a substrate surface prior to diamond coating deposition via a pretreatment stage using an unmodified oxy-acetylene combustion flame. The carbide layer may be formed at a temperature outside of the normal deposition temperature range and is treated as a separate step in the diamond growth process. The carbide layer serves to improve nucleation density, uniformity and adherence of the subsequent diamond coating. Many different types of substrates may benefit from the advantages of this invention.
