表层为TiC-Ni-10TaC-10Mo2C金属陶瓷层的硬质合金及其制备方法
摘要：
本发明提供了一种表层为TiC‑Ni‑10TaC‑10Mo2C金属陶瓷层的硬质合金及其制备方法，包括：芯部WC‑Co硬质合金层；设置在WC‑Co硬质合金层外部的表层金属陶瓷层；所述金属陶瓷层为TiC‑Ni‑10TaC‑10Mo2C与WC‑Co的复合层。本发明中的金属陶瓷颗粒有利于表层的耐磨性，WC‑Co硬质合金颗粒有利于硬质合金的韧性，因此使硬质合金的表层具有高硬度与耐磨性同时内部具有较好的韧性。
摘要（英）：

The invention provides a hard alloy with a surface layer as a metal ceramic layer. The hard alloy comprises a core part of a WC-Co hard alloy layer, and the surface layer of the metal ceramic layer arranged at the external of the WC-Co hard alloy layer; and the metal ceramic layer is a TiC-Ni-10TaC-10Mo2C and WC-Co composite layer. Metal ceramic particles facilitate wear resistance of the surface layer, and WC-Co hard alloy particles facilitate toughness of the hard alloy, so that the surface layer of the hard alloy is high in hardness and wear resistance, and the internal is better in toughness. The invention further provides a preparation method of the hard alloy with the surface layer as the metal ceramic layer.
