在第二次世界大战期中,为了满足军事工业的需要,各种生产枝术和操作,都有显著的发展与进步。钢的表面淬火法当然也不例外;除了火焰淬火和高频率电流淬火出现于世,普遍应用外,还有用浸液淬火法(Tauchhartung),来淬调质钢Vergtnngsstahl,含炭0.2到0.6％的炭素钢),使它的表面达到很高的硬度,而内部仍然保持相当的靱性。什么是浸液淬火:将要表面淬火的工件浸入高
During the Second World War, in order to meet the needs of the military industry, various production operations and operations have shown remarkable progress and progress. Of course, the steel surface hardening method is no exception; in addition to flame quenching and high-frequency current quenching appears in the world, generally used, but also by immersion quenching (Tauchhartung) to quench the quality of steel Vergtnngsstahl, containing 0.2 to 0.6% carbon Carbon steel), so that it reached a very high hardness of the surface, while still maintaining a considerable internal 靱 sexual. What is immersion quenching: the workpiece to be surface-hardened immersed in high
