Experimental equipment and methods for determining the cohesive strength of powder coatings

Abstract

Experimental equipment and methods for determining the cohesive strength of powder coatings

Maliy D.V., Medvedev P.N.

Incoming article date: 01.09.2021

The article describes the design of an experimental equipment (sample) for determining the cohesive strength of powder coatings in inactive and aggressive environments. A method for determining the mechanical characteristics of samples with coatings is presented, as well as data from the results of testing the cohesive strength of coatings based on nickel, PN60Y40, PN40Y60, iron-aluminum, coatings of self-fluxing alloys based on nickel PGSR-2, PGSR-3, PGSR-4.

Keywords: experimental equipment, cohesive strength, gas-thermal powder coatings, physical and mechanical properties, plasma spraying
