Patent number: 4146654
Abstract: A friction lining according to the invention is formed of bounded solidified previously molten particles formed on its support by plasma deposition; the base planes 0001 of a major proportion of the crytals in said lining are oriented in directions substantially parallel to the friction surfaces; the materials of which said linings are formed contain metals, metallic oxides or carbides having high melting points; they include cobalt, magnesium, neodymium, titanium, tungsten under its hexagonal form, yttrium, nickel under its hexagonal form, MoC, Mo.sub.2 C, NbC, Nb.sub.2 C, Ta.sub.2 C, WC, W.sub.2 C, V.sub.2 C, Cr.sub.2 O.sub.3, TiO.sub.2 ; they may contain under an alloyed form proportions of non hexagonal materials, including molybdenum, chromium, aluminum, copper, iron, the non hexagonal nickel, niobium, B.sub.4 C, TaC, TiC, Cr.sub.3 C.sub.2, VC, ZrC, ZrO.sub.2, Al.sub.2 O.sub.3, which do not affect the hexagonal structure of the alloys obtained.
