    模具制造表面工程技术的进展

    河北振通塑料模具厂深知模具材料是模具工业的基础,但即使是模具材料仍难以满足模具的较高综合性能的要求,采用表面工程技术可在一定程度上弥补模具材料的不足。可模具制造的表面工程技术十分广泛,既包括传统的表面淬火技术、热扩渗技术、堆焊技术和电镀硬铬技术,又包括近20年来迅速发展起来的激光表面强化技术、物理气相沉积技术、化学气相沉积技术、离子注入技术、热喷涂技术、热喷焊技术、复合电镀技术、复合电刷镀技术和化学镀技术等。而稀土表面工程技术和纳米表面工程技术的进展必将进一步推动模具制造的表面工程技术的发展。在此仅介绍稀土表面工程技术和纳米表面工程技术。

    (5)把稀土元素加入镀层可采用电刷镀、电镀等电沉积方法。稀土甘氮酸配合物的加入使镀层防氧钝化寿命明显提高;稀土元素有催化还原so2的作用,可以抑制ni-cu-p/mos2电刷镀镀层中mos2的氧化,明显改善了镀层的减摩性能,提高了抗腐蚀的能力,使模具型腔表面的耐磨寿命延长近5倍。河北振通模具厂对先进的技术和方法非常感兴趣,不断的吸纳先进的生产技术才能跟上市场需求和经济的发展规则,本厂生产盖板模具水泥模具等产品都是顺应市场的需要,大力加工生产的。
