 Central aim of organisation
Nano-crystalline diamond coatings for different applications: wear, tribology, luxury, life science, bio-sensors

 Briefly describe your organisation
Since 1996 p-BeSt coating produces diamond layers according to a unique and patented coating process. The uniqueness lies in the smallness of the single diamond crystals, that are approximately ten-thousand times smaller than a human hair (crystal size app. 10nm). Many of the outstanding properties of the layer are made possible by this crystal size and allow the application of diamond coatings in totally new areas.
The p-BeSt diamond coatings are presently used in the following areas:

- Cutting industry
- Luxury goods
- Life Science: implants, tissue engineering, bio-sensor
- Electronics

 RTD Experience
rho-BeSt is an innovative SME located in Innsbruck/Austria and founded in 1996 with business area of diamond coating for different applications. The self-developed deposition technique is based on a modified hot-filament process realised in 1994 resulting in pure diamond films with crystallite sizes ranging from micrometer to nanometer regime (nano-crystalline diamond – NCD). Industrial mass production is established since 2000 especially for wear protection of tools for machining graphite, aluminium and aluminium alloys as well as fibre-reinforced composites. Beside production, rho-BeSt is performing research in interdisciplinary fields like:
 wear and friction of NCD-coatings: drilling and milling tools, bearings, seals, etc.
 development of NCD-layers for machining new materials and composits
 development of NCD strong adhesion (including matching interlayers) on different substrates, steel, low temperature material (CMOS)
 bio-sensors (nano-gap sensor, smart sensor for in situ bone growth)
 implants/substrates for tissue engineering: oriented, controlled cell growth (bone and soft tissue)
 MEMS/NEMS (FBAR for mass detection (pico- to attogram))
A high international level of collaboration reflects the success of rho-BeSt nano-crystalline diamond (NCD) und ultra-nano-crystalline diamond (UNCD) material. Most of the results are published in peer-reviewed journals [see publication list of rho-BeSt].
