Abstract
Synthetic diamond film produced by chemical vapor deposition can be crushed to obtain diamond grit which has useful abrasive properties. The flexibility of CVD deposition processes in determining diamond film properties means that CVD diamond grit properties can be tailored to particular abrasive applications. In a disclosed embodiment, the grit particles are coated with a magnetic material. The coated grit particles can then be aligned with a magnetic field, and the coated grit particles are bonded to a matrix while aligned. In a further disclosed form of the invention, a chemical vapor deposition system, such as an arc jet plasma deposition system, is provided in a chamber.
