내(耐)이로젼성 재료는 연속부 및 불연속부를 갖는다. 연속부는 연속한 구조를 갖는다. 불연속부는 연속부의 내부에 불연속인 구조로 되도록 배치되어 있다. 당해 불연속부는 평균 입경 1㎛ 이하의 입자로 이루어진다. 또한, 당해 불연속부는 연속부보다도 표면 경도 및 영률이 높은 재료로 이루어진다. An erosion resistant material has a continuous portion and discontinuous portions. The continuous portion has a continuous structure. The discontinuous portions are arranged inside the continuous portion to have a discontinuous structure. The discontinuous portions are formed of particles having an average particle diameter of 1 µm or less. Further, the discontinuous portions are formed of a material having a surface hardness and a Young's modulus higher than those of the continuous portion.
