The addition of silicon carbide (SiC) and aluminum oxide (Al2O3) as reinforcements in aluminum metal matrix composites can provide several benefits, including increased strength and stiffness: SiC and Al2O3 are very hard materials with high strength and stiffness. Adding these reinforcements to the aluminum matrix can significantly increase the overall strength and hardness of the grease, making it more suitable for use in structural applications. Improved wear resistance: They have excellent wear resistance, which can increase the durability and lifetime of the grease. This is particularly useful in applications where MMC is exposed to high levels of wear and erosive forces. Improved thermal stability: SiC and Al2O3 have high melting points and good thermal stability, which can help improve the overall thermal stability of the grease. This is particularly important in high temperature applications where the grease may be exposed to thermal cycling or high temperatures. Improved corrosion resistance: SiC and Al2O3 have good corrosion resistance, which can help improve the overall corrosion resistance of the lubricant. This is especially useful in applications where the aluminum complex grease will be exposed to corrosive environments. In general, the addition of SiC and Al2O3 as reinforcement to aluminum complex greases can significantly improve the mechanical, thermal and corrosion properties of the material, making it more suitable for a wide range of applications.
