Abstract
Thermal spraying allows forming of protective coatings with high wear and corrosion resistance, which are successfully applied in the aviation industry on an aircraft engine. In the presented paper, the WC-CrC-Ni carbide coatings on titanium substrate with the use of an Atmospheric Plasma Spraying (APS) process were formed. The aim of this work was to determine optimal APS plasma spraying parameters, which will allow producing the relatively thick coating with as low as possible porosity. The microstructure of obtained carbide coatings was observed with the help of the optical microscope (OM) and scanning electron microscope (SEM). Moreover, the phase composition of produced coatings using X-ray diffraction (XRD) was determined. The obtained results of investigations revealed that the appropriate selection of process parameters (powder feed rate, power current, and plasma gases H2/Ar flow ratio) allows producing the relatively thick coatings, which are characterized by low porosity.
