摘要
对国内外凿岩用硬质合金的现状及发展态势作了分析、评述。随着我国硬质合金生产工艺技术与装备的进步,我国凿岩用硬质合金常规牌号的质量水平逐渐与国际水平接近,由于国产合金价格较低,替代国外牌号凿岩硬质合金具有很好的性价比。在新技术应用方面,我国在金刚石复合片、金刚石复合齿用于凿岩工具方面具有一定优势,但是在超粗晶粒硬质合金、梯度合金等方面的研究与应用,与国外还存在一定差距。
The paper analyzed and commented the actuality and development trend of cemented carbide for rock drilling applications at home and abroad.With the progress of the technology and equipments for producing cemented carbide,the quality of homemade cemented carbide is gradually close to international level.In addition,the homemade cemented carbide has better ratio of price to performance than the foreign cemented carbide with same specification due to low price of homemade cemented carbide.In terms of application of new technologies,homemade diamond compact and diamond segment for rock drilling tool has some advantages,while the national study and application of super-coarse granule cemented carbide and gradient cemented carbide is weak.
