遵照毛主席关于“教育必须为无产阶级政治服务,必须同生产劳动相结合”和“独立自主、自力更生”的教导,为了提高硬质合金机卡具的寿命,满足我国社会主义建设的需要,以实际行动反击右倾翻案风,我们在工人阶级的领导下,工人、干部、工农兵学员和教师三结合,进行了硬质合金电解渗硼的试验。 硬质合金是一种优越的工具材料,它具有很高的硬度,耐磨性和抗击强度,弹性模数也高。但是,较高的抗弯强度和冲击韧性却不能与较高的硬度同时兼备,这是一对矛盾。
In accordance with Chairman Mao’s teachings on “education must serve proletarian politics, must be integrated with productive labor” and “be independent and self-reliance”, in order to raise the life expectancy of carbide carriages and meet the needs of socialist construction in our country, In response to the right-wing overthrow of the bill, we carried out experiments on the carburizing of cemented carbide by the combination of the workers, cadres, workers, peasant and soldiers, and teachers under the leadership of the working class. Carbide is a superior tool material, it has high hardness, wear resistance and impact strength, modulus of elasticity is also high. However, the higher flexural strength and impact toughness can not be both high hardness, which is a contradiction.
