this paper deals with the investigation of the microstructure and hardness of steel samples cladded with satellite 6-wc composites by using gas tungsten arc welding (gtaw) process. for this purpose, steel samples were coated with unreinforced and reinforced stellite (by 20, 30 and 40 wt.% wc). the cladded samples were evaluated by metallographic studies, microhardness measurement and x-ray diff...
The capability of manufacturing coatings is of central importance in engineering design. Many components require nowadays the application of additional layers, to enhance mechanical properties and protect against hostile environments. Supersonic Laser Deposition (SLD) is a novel coating method, based upon Cold Spray (CS) principles. In this technique the deposition velocities can be significant...
The CrS/NbC Co-based self-lubricating composite coatings were successfully fabricated on Cr12MoV steel surface by laser clad Stellite 6, WS₂, and NbC mixed powders. The phase composition, microstructure, and tribological properties of the coatings ware investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectrometer (EDS), as well as dry s...
