概述钢结硬质合金用作模具材料已日益广泛,表现出极大的生命力,业已积累了大量的经验。目前在我国生产与使用的钢结硬质合金有TiC型(如GT35)与WC型(如TLMW50)两大类,用作冷变形模具材料具有良好的机械性能与工艺性能。模具寿命成数十倍,甚至上百倍地提高,取得了极好的效果。工模具与机械零件因磨耗超差造成报废,而磨耗是一个比较复杂的问题,其影响因素比较多,目前尚未获得十分清晰的结果。从普通高碳高合金材料来看,一般认为材料硬度愈高,
Overview Steel bonded carbide used as a mold material has become increasingly widespread, showing great vitality, has accumulated a wealth of experience. At present, the steel hardened cemented carbide produced and used in our country has two main categories of TiC type (such as GT35) and WC type (such as TLMW50), which has good mechanical properties and process properties for cold deformation mold material. Mold life into a few times, even a hundred times to improve, and achieved excellent results. Die and machinery parts due to excessive wear and tear caused by scrap, and wear is a more complex issue, its influencing factors are more, has not yet been very clear results. From the common high-carbon high-alloy materials, it is generally believed that the higher the hardness of the material,
