Grant: CCI Applied Research and Development Grants

The company K&Y Diamonds reached to CMQ to assess the lapping ability of lapping discs manufactured following the US4532737 Patent. K&Y Diamonds is a Canadian company specialized in the manufacturing of diamond tools. Diamond, known as the hardest material available on earth, required diamonds to be worked on. The lapping discs manufactured following the above-mentioned patent are supposed to allow a rather fast and efficient lapping of the diamond, with acceptable wear of the lapping discs themselves. The procedure described involved hot pressing at high pressure, which is not easily reachable for the required dimensions. CMQ can manufacture test coupons of reduced size by using hot press route. This avenue will allow the CMQ team to verify the microstructure desired for such material. CMQ research team proposed to K&Y Diamond members to develop manufacturing solutions to reach equal material by the use of Hot Isostatic Pressing (HIP) and High Velocity Oxy-Fuel (HVOF) thermal spray technique. Whether hot press, HIP or HVOF route is embraced, the alloy described in the patent will be produced and atomized at CMQ facility. The specimen produced will be characterized by metallographic analysis as well as Pin-On-Disc wear testing. Finally, full-sized samples will be produced for K&Y Diamonds to test in their own lapping laboratory.
