硬质合金的热处理与应用研究

本文介绍了WC-Co硬质合金具有高硬度、高耐磨、高红硬性和一定强韧性等性能，该合金烧结后直接使用，广泛应用于工具、刀具、量具、模具和耐磨零件等领域。与普通熔炼钢材比，使用寿命几倍、几十倍提高。研究发现，含钴硬质合金可热处理强化，其性能和寿命在原有基础上又有新的提高，技术经济效益显著。

Tthis article introduced the WC-Co cemented carbide which has high hardness, abrasionproof and red hardness and ohdurability capability. It can use directly after sinter, widely applies in domains such as tool, cutter, measuring tool, mold and abrasionproof hardware. Compare with melting steel, the useful life increase severalfold or several decuple. The research indicated that, cobalt cemented carbide can be heat treating intensify .The capability and natural life has more improvement on the basis of prime, and has remarkable technology economic benefit.
