Abstract The article presents the results of experimental studies of the properties of polymeric coatings obtained various flame-spraying methods. Changing the properties of the coatings with the change of the ratio of the volume of air and propane fuel mixture has been investigated. Maximum adhesion strength to the substrate and the lowest tension are registered in the coatings obtained by using the oxidative flame (air ratio and propane = 28 ... 30). Modification of polymer by additives of ultradisperse diamond-graphite particles reduces the effect of influence of the fuel mixture for coating adhesion. With the increase of the content of the oxidant in the composition of the fuel mixture torch observed increase in the size of supramolecular structures.
Keywords polymer coating, flame spraying, polymer powders, polymer cords, coating properties
