popup.description2
The method of detonation spraying of composite materials of the TiCrB2 – NiAlCr system restored non-magnetic plates of the magnetic fluid sealant and fitting under the bearing bearings of the pump shaft. The cutting edges of disc knives for cutting plastic are strengthened by the method of electrospark alloying. Restored parts have met most of the requirements (hardness, density, wear resistance) and are undergoing production tests. The optimal conditions under which the spraying of the developed materials of the TiCrB2–NiAlCr system will have the greatest technical and economic feasibility have been determined. Recommendations for the operation of restored parts (mechanisms), in which their operation will be minimal. They concern both the improvement of the operating conditions of the parts (better sealing of the bearing units, the reduction of the feed rate of the processed material, etc.) and the change of certain characteristics of the coatings themselves (roughness, hardness).
