模具是轻工、电子、机械等行业的重要基础工艺装备、它对产品质量,更新换代都具有不可忽视的重要性。我国模具的使用寿命和国外同类模具相比,目前尚存在一定的差距。下面推荐由山东省科学院金属材料开发中心研制的用五氧化二铌硼砂盐浴渗铌新工艺,经在不同类型的模具表面处理后,证明 Die is light industry, electronics, machinery and other industries an important basis for technology and equipment, its product quality, upgrading have the importance that can not be ignored. The service life of our mold compared with similar foreign mold, there are still some gaps. The following recommended by the Shandong Provincial Academy of Sciences metal material development center developed with niobium pentoxide bismuth niobium infiltration niobium new technology, after the different types of mold surface treatment, that
