II. Heating temperature and time before dynamic hot pressing, protective atmosphere in sintering and dispersity of solid lubricant [Elektronische Daten] [Yu. Dorofeev, G. Musaélov, A. Mamedov] Conclusions: With heating temperature before DHP equal to 1000°C and heating time of 1200 sec, the specimens have the best antifriction characteristics. On the other hand, an increase of τDHP impairs the physicomechanical properties (except impact toughness), and a change of the temperature has an ambiguous effect on them. Comparatively good physicomechanical properties and the smallest linear wear were found in specimens sintered in dissociated ammonia, in vacuum, and in a container with fusible seal. Specimens sintered in dissociated ammonia and dried hydrogen have a low friction coefficient. The effect of the dispersity of inclusions of solid lubricant on the mechanical properties is imperceptible, but on the friction coefficient and on linear wear it is substantial. Optimal is the use of particles of the fraction +100 μm: thanks to their spongy shape they adhere more strongly to particles of the matrix, and that has a favorable effect on the antifriction properties.
