Silicon carbide applications

Since silicon carbide contains silicon and carbon, silicon enters molten iron during melting, and most of the carbon burns. It is worth noting that due to the reasons of silicon carbide, the main element of the composite additive is high silicon carbide off-cuts (SIC) particles play a core role in the casting, the finer the silicon carbide particles, the stronger the nucleation capacity. Discovered under observation; The interface between silicon carbide particles and the matrix is effectively bonded, there is a high-density dislocation around the particles, and the crystallization increases, so that the grains are refined, and the number of eutectic clusters and pearlite changes significantly. Because silicon-carbon alloy has strong nucleation ability, it can change the morphology of graphite and refine the structure, thereby improving mechanical properties and preventing leakage, so that the waste rate is reduced and the rewelding rate is reduced.
