Open the CIPO recordAbstract From the Canadian patent
A method for coating cluster compacts of polycrystalline diamond and CBN particles is provided wherein the cluster compact is not exposed to high temperatures due to selective heating of the coating/cluster compact interface with the use of laser energy. Strong coatings can be formed on thermally sensitive compacts which allow such compacts to be brazed directly to a tool holder.

Why it's free to use
- Filed May 7, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 7, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 7, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
