Abstract
The paper considers various methods of machines and equipment service life and safety improvement by applying coatings on the rapidly wearing part surfaces. The authors showed the advantages of applying thin polymeric coatings on finished parts and metal pieces and machine parts under repair. The work objective is to improve the service life of machine parts, die tooling, tools and other goods by means of increase of their wear resistance. For this purpose, the authors created a new method of applying polymeric coatings on metals and took out the RF patent for the invention. Using the experimental conditions the authors selected the materials for a coating (SKU PFL-100 polyurethane) and the binding agent (silbond 49 SFS), as well as developed the processing procedure of applying polyurethane coating: defined the sequencing of performed operations and their characteristic parameters. Under the actual operating conditions, the experimental data showed that even such parts as the adjusting and sealing rings of suction dredges of hydraulic excavators, after the renovation using the applying of polyurethane coating, are able to transfer fifteen times more sand than new rings without coating. Except the service life increase, the polyurethane coating applying impart a number of good properties (advantages): the increase of load impact resistance, noise and/or friction reduction, good weather, corrosion, chemical resistance. Eventually, the polymers due to their durability, corrosion resistance, easy workability and low price will be able to substitute such expensive materials as stainless steel and nonferrous metals. The developed and patented in the RF method of producing laminated moldings proves this statement.
