APPARATUS FOR MANUFACTURING DIAMOND-LIKE COATING Russian patent published in 1997 - IPC

FIELD: artificial diamonds. SUBSTANCE: invention concerns applying hard, wear resistant, and chemically inert amorphous diamond-like coatings up to 50 mcm thick and showing high adhesion to all-size articles. Apparatus has chamber with inert gas inlet and outlet pipes, two cathodes, anode, and magnetic field source in the form of constant magnets with alternating polarity equidistant from article surface. One of cathodes is mounted on magnetic field source and the second one is article itself. Anode is made in the form of a plate disposed between cathodes, holes in the anode, as to their shape, size, and number, corresponding shape, size, and number of constant magnets. Constant magnets are mounted on magnetic conductor of soft-magnetic material. Diamond-like coating is applied by way of imposing positive potential (commonly 1 kV) on anode in hydrocarbon medium under pressure. EFFECT: increased productivity. 2 cl, 2 dwg
