Abstract

This article is devoted to reconditioning of working surfaces of equipment exposed to abrasive, corrosive, and cavitation wears. Importance of implementation of rational reconditioning methods at enterprises is discussed. The reasons and properties of wear types are listed, peculiar attention is paid to cavitation wear and its consequences. Classification of faults and reconditioning methods of worn working surfaces are described, it is proposed to use composite materials on polymer basis with various fillers; composite materials with ceramic fillers are more preferred as the most wear resistant ones and providing restoration of numerous wears of process equipment and pipelines. The article presents physicomechanical properties of compounds with ceramic fillers. In order to solve the formulated problems, practical proposals are given with regard to application of composite materials available at Russian market. The most suitable materials are determined on the basis of quality/price ratio. Examples of performed activities are given, economic efficiency of reconditioning using composite materials is highlighted. Major advantages of the proposed technology are described.
