FIELD: technological processes. ^ SUBSTANCE: wood is modified by means of introduction of metal into its porous structure during thermal decomposition of nickel tetracarbonyl vapours inside wood, vapours of nickel tetracarbonyl are supplied into bottom part of wood stock with the speed of not more than 20 l/hr per 1 cm2 of cross section area in process of heating zone displacement downright with the speed of 12-15 cm/hr, at that for modification wood is used with humidity of not more than 2 wt %. ^ EFFECT: increase of wood heat conductivity and increase of resource of its operation in friction units. ^ 2 cl, 1 dwg, 2 tbl, 7 ex
