Further, it forms a solid solution in the matrix to increase the strength of the coating layer. If it is less than 0.2%, the temperature difference between the solid phase and the liquid phase becomes large, so that when the coating layer is solidified by the centrifugal casting method, double carbides and double borides tend to segregate.
