Synthesis of reinforced magnesium embedded in carbon matrix by using thermionic vacuum arc (TVA) technology

摘要

The aim of this work is to control the synthesis of nanocrystallinemagnesium embedded in hydrogen-free amorphous carbon (a-C) matrix byThermionic Vacuum Arc (TVA) method on glass, silicon and OLC 45 specialsubstrate. Nanostructured coatings with homogenous surface without any faults(pinholes and cracks) were achieved at low temperatures to not affect the materialsproperties. The results on the morphology, composition and wettability of the coatingswere investigated in terms of TEM, SEM with X-ray detection (SEM/EDX) and freesurface energy (See System). Reports on optimized coatings by a graded structure andadjusting stress level were also discussed.
