摘　　要：叙述和讨论了RB40钢结硬质合金螺栓热冲凹模，复合强化处理的工艺和机理以及试验结果表明．通过复合强化处理的RB40螺栓热冲凹模的使用寿命，比熔化钢螺栓热冲凹模可提高30～40倍。The paper dedcribed and discussed the teohnic and the mechanism of complex strengthening processing of Rb40 steel-bonded cemented carbide as well experimental results,the results shows that the service life of Rb40 bblt hot-punching die by complex strengthening processing can increase 30-40 tinmes than that of meliting steel.

关 键 词：RB40钢结硬质合金 螺栓热冲凹模 复合强化处理
