dc.description.abstractIn this paper, the different application of niobium carbide coatings onto hard carbide substrate was investigated using scanning electron microscope (SEM), Xray diffractometer (XRD) and micro-hardness. The paper conducted a study on the friction coefficient and wear resistance as a function of load friction couple, for a series of NbC type thin layers; micro-hardness value measured in the coating layer was 29.800 MPa. Scanning Electron Microscope was used to investigate the coating morphology and interface structure. X-ray mapping was also performed to characterise the elements in a semi-quantitative analysis. A Dron X-ray diffractometer with Mo Kα radiation operating was used for phase(s) identification. Adherence was assessed using a layer fingerprinting method using Rockwell hardness testers. CVD NbC coatings usually show only moderate or even poor corrosion protection for hard carbide substrates.ro_RO
