Abstract
The paper provides the results of studying the condition of the working pivot of thrust bearings made of reaction- sintered silicon carbide-based ceramics (SiSiC-ceramics) removed from the seal section of the electrical centrifugal pump system. The working surface of the pivot demonstrates numerous service-induced damages of different origin resulting from friction. Based on categorization of these damages, recommendations were made concerning the improvement of the ceramic thrust bearing design.
