Mechanical Properties in MMC of Aluminum Alloy (A356/LM25) Matrix and Boron Carbide …
Boron carbide has low wettability property, hence it cannot be readily mix with Aluminum melt. In order to improve the wettability and remove moisture content it is preheated to 480 C for 2 hour in a muffle furnace. Table 3: Properties of Boron Carbide (B 4 C) 4
Silicon Carbide is among the hardest of ceramics, and retains hardness and strength at elevated temperatures, which translates into among the best wear resistance also. Additionally, SiC has a high thermal conductivity, especially in the CVD (chemical vapor deposition) grade, which aids in thermal shock resistance.
