Patent number: 5364423Abstract: 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.Type: GrantFiled: May 6, 1993Date of Patent: November 15, 1994Assignee: Norton CompanyInventors: Louis K.

Patent number: 4907377Abstract: Disclosed is an improved method for making a polycrystalline diamond compact comprising subjecting a mass of diamond particles, which mass is adjacent a cemented metal carbide mass containing a catalyst, to a high pressure/high temperature process which results in a compact characterized by diamond-to-diamond bonding. The improvement in such process comprises placing a second catalyst source adjacent the diamond mass, said second catalyst having a melting point which is lower than the melting point of the catalyst of the carbide; and subjecting said mass to high pressure/high temperature sintering at a temperature above the melting point of the second catalyst, but below the melting point of the carbide catalyst, for causing said second catalyst to selectively diffuse through said mass for forming said polycrystalline diamond compact. The preferred catalyst is a mixture of cobalt and boron.Type: GrantFiled: June 16, 1988Date of Patent: March 13, 1990Assignee: General Electric CompanyInventors: Frank J. Csillag, Harold P. Bovenkerk

Patent number: 4797326Abstract: Disclosed is a process for fabricating a composite polycrystalline diamond or cubic boron nitride (CBN) compact. Briefly, the process is conducted by mating a pre-formed sintered polycrystalline diamond or CBN compact and a plastically deformable support, and subjecting the mated composite compact to elevated temperature and pressure conditions sufficient to plastically deform the support into attachment with the compact. The temperature, pressure and time of application are inadequate to cause degradation of the diamond or CBN compact. The product configuration may be a conventional layered compact or may be a wire drawing die having a polycrystalline diamond or CBN core with a support jacket of a material such as a cemented metal carbide.Type: GrantFiled: January 14, 1986Date of Patent: January 10, 1989Assignee: The General Electric CompanyInventor: Frank J.
