Abstract: A method for the growth of a SiC single crystal comprisingintroducing a seed crystal of SiC single crystal having an exposed face deviating from the {0001} plane by an angle .alpha..sub.1 of about 60.degree. to about 120.degree., typically about 90.degree. and SiC powder as a raw material into a graphite crucible,elevating the temperature of the SiC powder in an atmosphere of inert
Several heating processes have been applied for this purpose by using SiC, either in form of powder particles or monocrystalline substrate. In this work, instead of using an expensive commercially available SiC wafer, a polycrystalline SiC substrate was obtained, based on powder metallurgy process, in order to explore the synthesis of graphene layers on its surface by using a CO 2 laser beam
The industrial 3D printing market for the laser metal deposition technology is expected grow at the highest CAGR during the forecast period. Laser metal deposition technology can be used to print the parts for both repair and production purposes, which makes it suitable for use in manufacturing industries.

Preceramic paper sheets containing 76.8 wt.% SiC powder, 20 wt.% cellulose pulp, and 3.2 wt.% retention agent and binder was processed by LOM to green bodies which then were pyrolysed at 800 C with formation of SiC-C bodies and subsequently infiltrated
Laser alloying of aluminum AA1200 was performed with a 4.4 kW Rofin Sinar Nd:YAG laser to improve the surface hardness. Alloying was carried out by depositing Ni, Ti and SiC powders of different weight ratios on the aluminum substrate. The aim was to form surfaces on aluminum reinforced with metal matrix composites and intermetallic phases. The laser parameters used were 4 kW power and 10 …
