.... This study examined the effect of activator type through the analysis of microstructures, phase identification and hardness of SiC coatings. Findings The as-coated specimens showed the formation of the β-SiC phase with more than 150 µm thickness on the graphite surface. Moreover, the hardness value...

... laser. Second, the cladding layers with different laser scanning speeds are composed of Ti₂Ni, TiN_0.3, TiC, TiB, α-Ti and other phases. Finally, precision balances, friction and wear testing machines were used to analyze and test the structure, phase, hardness, wear amount...

... has the lowest microhardness. In all joints, the tensile fracture locations match to the minimum hardness values. Field emission scanning electron microscope fractography of tensile tested specimens reveals heterogeneous modes of brittle, shear and ductile fracture. Three-point bending analysis...
