sp3 Diamond Technologies has received two new orders for its Model 650 hot filament chemical vapor deposition (HFCVD) diamond reactor. The India Institute of Technology (IIT) Madras will install one system as part of the expansion of its Nano Functional Materials Technology Centre (NFMTC). The second order comes from an unnamed Japanese manufacturer, sp3 said.

“These orders, along with the Heriot-Watt installation at the end of last year, highlight the increasing interest not only in the material itself, but also in a product capable of delivering large scale and cost-effective thin-film diamond deposition,” said Dwain Aidala, President and COO of sp3 Diamond Technologies. “The Model 650 is the only tool with this capability and, as such, leads the industry in providing CVD diamond to a growing number of market segments worldwide.”

“Nanocrystalline diamond films are considered to be the best candidates for wear resistant and other tribological coating applications because of its high hardness and low friction coefficient, combined with high thermal conductivity,” said Prof. M.S.R. Rao of IIT Madras. “Hot filament CVD ensures high uniformity over large areas for planar and non-planar surfaces. Nanocrystalline diamond-coated tungsten carbide dies can increase their lifetime by a factor of 10-15 times.”
