  • Process for producing synthetic diamonds
    Patent number: 4085196
    Abstract: A process for producing synthetic diamonds which comprises the synthesis of diamonds from a charge consisting of graphite or a carbonaceous material capable of being graphitized and a catalyst; as the latter use is made of a metalgraphite laminar compound of a transition metal, wherein said metal is interposed between the graphite layers and chemically bonded therewith.Said catalyst makes it possible to shorten the duration of the synthesis down to several seconds and carry-out the synthesis at a temperature of below 1,200.degree. C. The resulting diamond crystals are colorless and transparent.

  • Method of testing wear resistance of articles on the basis of polycrystalline cubic boron nitride
    Patent number: 3978711
    Abstract: A method of testing wear-resistance of articles which comprises measuring the rate of propagation of ultrasonic oscillations in a reference article which has the lowest admissible wear resistance. The rate of propagation of ultrasonic oscillations in the articles being tested is compared with the rate in the reference article. The reference article is placed into a liquid in the suspended state and the articles being tested are placed into the same liquid. Those articles, which ascend to the surface, are rejected.
