Abstract

An electroplating-electrophoretic procedure for producing composite coatings using a combination of electroplating and electrophoretic methods, followed by liquid phase sintering at the eutectic formation temperatures, has been studied. Finely divided Mo and Mo2C powders produced by low-temperature catalytic reduction of molybdenum trioxide and subsequent molybdenum carbiding were employed, and the main electrophoretic deposition mechanisms have been estabished. Electrophoresis parameters have been examined in terms of their effect on the precipitates formation rate and their structure. This procedure enables components operating under corrosion-erosion wear conditions to be protected and their service life increased by a four or fivefold factor.
