Abstract

Modified wood is used in the form of sliding bearings in friction units of various machines and mechanisms, mainly operating under severe operating conditions (combines, rock loading machines, belt conveyors). Wide use of such bearings is constrained by low thermal conductivity of wood. Technology and equipment for metallization of wood with tetracarbonyl pairs Ni(CO)4 have been developed to increase thermal conductivity of modified wood, when metallic nickel is deposited as a continuous film with a thickness of 0.4 μm. As a result, thermal conductivity of wood increases from 0.4 W/m/degree to 10-15 W/m/degree with a nickel content of 2-5% by weight of wood. Use of bearings made of metalized wood is possible at a temperature of 120°C in the friction zone, instead of 80°C – for conventional pressed wood.
