The methods of functional coatings application onto flat sealing surfaces of the stop valves parts

Abstract

The actuality and effectiveness of the stop valves worn-part reclamation are presented. The results of the comparative analysis of the known techniques of protective finishing onto the sealing surface for valves service properties restoration are given. The classification of anti-abrasion coating application methods are given depending on their properties and characteristics. Factors and conditions influencing the abrasion resistance of the coating material and its adhesion with the detail base material are defined. The usage of the freezing out coating process onto the flat sealing surfaces of the stop valves parts are shown.
