PROPERTIES OF PLASMA AND HVOF SPRAYED COATINGS
Journal Title: Tribologia - Year 2010, Vol 234, Issue 6
Abstract
Nowadays plasma spraying and supersonic spraying processes are widely applied in many branches of industry. This paper presents current achievements in this area and the results of investigations of plasma and supersonic sprayed NiCrBSi/Fe2O3 coatings. It was found that the microstructures of coatings depend on the method of spraying. The tests show that supersonic coating possesses lower porosity and scuffing resistance. The investigations concluded that supersonic sprayed coatings posses higher wear resistance. The increase of the Fe2O3 portion in the composite coating causes a decrease of the wear resistance of coatings.<br/><br/>
