高硬度耐磨复合钢板及其制备方法
摘要：
本发明涉及一种耐磨板，具体公开了一种高硬度耐磨复合钢板，该高硬度耐磨复合钢板，包括基板和位于基板表面的合金耐磨层，所述合金耐磨层包括以下重量百分含量的组分：C：5‑12%，Cr：25‑42%，Si：0.15‑1.5%，Mn：0.3‑1.0%，Co：0.5‑1%，V：1.0‑1.5%，Mo：0.8‑1.3%，Y：0.6‑0.8%，W：1.2‑2.0%，Fe：余量。本发明还公开了高硬度耐磨复合钢板的制备方法。本发明的高硬度耐磨复合钢板通过优化合金耐磨层中各组分及其含量，各元素之间相互作用，所制得的复合钢板具有表面光滑平整、耐磨性好、耐磨区表层与底部硬度相近、使用寿命长的特点，并且拥有良好的冶金结合强度、耐冲击、耐高温以及耐腐蚀性能。
摘要（英）：

The invention relates to a wear resisting plate, and in particular, discloses a high-hardness wear resisting composite steel plate. The high-hardness wear resisting composite steel plate comprises a substrate, and an alloy wear resisting layer positioned on the surface of the substrate; and the alloy wear resisting layer includes the following components in percentage by weight: 5-12% of C, 25-42% of Cr, 0.15-1.5% of Si, 0.3-1.0% of Mn, 0.5-1% of Co, 1.0-1.5% of V, 0.8-1.3% of Mo, 0.6-0.8% of Y, 1.2-2.0% of W, and the balance of Fe. The invention further discloses a preparation method of the high-hardness wear resisting composite steel plate. The high-hardness wear resisting composite steel plate optimizes all the components and the contents thereof in the alloy wear resisting layer and the interaction among all elements, so that the prepared composite steel plate has the characteristics of smooth surface, good wear resistance, similar hardness of the bottom layer and the bottom of a wear resisting area and long service life, and achieves excellent metallurgic bonding strength, impact resistance, high-temperature resistance and corrosion resistance.
