Description

一种钴合金冷镦工艺润滑剂组合物
技术领域
本发明一种钴合金冷镦工艺润滑剂组合物属于金属加工润滑剂领域。
背景技术
钴基高温合金是高温合金中的一种，它是以钴作为主要成分，含有相当数量的镍、铬、钨和少量的钼、铌、钽、钛、镧等合金元素，偶而也还含有铁的一类合金。根据合金中成分不同，它们可以制成焊丝，粉末用于硬面堆焊，热喷涂、喷焊等工艺，也可以制成铸锻件和粉末冶金件。与其它高温合金不同，钴基高温合金不是由与基体牢固结合的有序沉淀相来强化，而是由已被固溶强化的奥氏体fcc基体和基体中分布少量碳化物组成。钴基高温合金中碳化物的热稳定性较好。钴基高温合金是含钴量40～65％的奥氏体高温合金。在730～1100℃条件下具有一定的高温强度、良好的抗热腐蚀和抗氧化能力。适于制作航空喷气发动机、工业燃气轮机、舰船燃气轮机的导向叶片和喷嘴导叶以及柴油机喷嘴等。
冷镦加工是利用模具在常温下对金属棒料镦粗(常为局部镦粗)成形的锻造方法。冷镦是另一种形式的镦锻工艺。更具金属型变理论，在常温下对金属坯料施加一定的压力，使之在模腔产生变形。按规定的形状和尺寸成形。冷镦工艺广泛应用于中小零件以及各种类型的标准件。
冷镦工艺的主要特征是无切削加工，材料利用率高，利用率达80～90％，且金属材料流线不会被切断，因此成品强度比切削加工或铸造成型零件强度更高，在一定的批量生产条件下，冷镦加工成本要比其它加工成本低得多，适用于通常需要切削件以及紧固件等形状对称的产品加工。产品的尺寸精度、重量精度及力学性能等都能达到较高的要求。
润滑剂应具有的特点：良好的承载抗磨性、挤压性(不拉毛、拉伤、有效延长冲模的使用寿命)、低温流动扩散性、润滑性、冷却性，油膜强度大、油膜厚度保持稳定，无异味、不刺激皮肤等。钴合金冷镦工艺润滑剂是要提高工件光洁度，保护被加工零件表面不锈蚀和氧化，减少动力能耗，低温流动性好，良好的抗泡性、抗乳化性、热氧化定性好，减少沉淀物和漆膜的产生，成型件易清洗。
发明内容
