Adhesion of the powder flame sprayed coatings using Fe-Cr-Co-Mo powder

Agnieszka Rzeźnikiewicz, Piotr Centrowski

Abstrakt


The aim of the research was to assess the adhesion of the powder flame sprayed coatings to the previously prepared substrate. The spraying tests were carried out using Rototec 51000 base powders which was Ni-Al-Mo alloys, then coated with an outer coating made of Rototec 19404, which is an alloy Fe-Cr-Co-Mo. The coatings were tested for adhesion in accordance with the PN-EN ISO 14916: 2017 standard and also topography tests of sprayed coatings using scanning electron microscopy.
