Research & Development

SP3 Diamond Technologies is the market leader in wide-area diamond deposition, thanks to our proprietary hot-filament chemical vapor deposition (CVD) technology, which enables growth of thin-film, wafer scale diamond coatings on a wide variety of substrate materials. While continued expertise in depositing and growing diamond onto substrates will always be part of our mission, SP3’s over-arching goal is enabling BEST OF BREED DIAMOND COATED PRODUCTS for our customers. So our technical core competencies and R&D efforts goes well beyond CVD diamond deposition. Some of our R&D efforts include:

  • Substrate materials analysis
  • Advanced substrate processes
  • Diamond to substrate adhesion research
  • Cutting tool edge preparation techniques
  • Diamond on silicon
  • Diamond on glass
  • BDD electrodes

Materials

SP3 Diamond Technologies utilizes is proprietary Hot-filament CVD (HFCVD) systems to coat substrates with polycrystalline diamond. There are a number of factors that determine whether a substrate material is suitable for CVD diamond coatings. Those materials that are excellent for HFCVD coating are:

  • Silicon carbide
  • Silicon
  • Tungsten carbide
  • Silicon nitride
  • Silicon dioxide
  • Diamond
  • Titanium
  • Niobium
  • Tungsten
  • Molybdenum

Materials that can be coated in certain cases are:

  • Quartz
  • Gallium Nitride
  • Graphite
  • Copper
  • Specialty Glass

Visit our Resources section if you would like more details regarding materials appropriate for HFCVD coating.

Cutting Tool Performance Testing

SP3 Diamond Technologies’ mission is to enable Best of Breed diamond coated cutting tools. In order to ensure that the performance of our diamond coatings is the best in the world, we have an in-house CNC machining center. This allows us to test, on a daily basis, our process advancements.
