Description

一种625合金拉拔润滑剂组合物
技术领域
本发明属于金属加工润滑剂领域，特别涉及一种625合金拉拔润滑剂组合物。
背景技术
625合金是一种镍铬钼铌合金，是镍基耐蚀合金。它具有良好的耐腐蚀性和较广的温度范围内(通常在980摄氏度以下)，都具有较高的强度。它具有较高强度是通过镍铬基它内含有的钼和铌等合金元素的固溶强化而获得，不需采用沉淀硬化工艺(金属在过饱和固溶体中硬化的一种热处理工艺)处理。625合金具有耐点蚀、耐缝隙腐蚀、耐冲压腐蚀、耐晶间腐蚀等特点。此外，在潮湿的氧化物中，很少存在固应力腐蚀而导致开裂的问题。比较容易焊接和采用标准的车间制造方法进行加工。由于这些特性，使其非常适合在高温、高湿、高盐雾的海洋腐蚀环境下使用。
钼元素的存在，使625合金具有耐点蚀和耐缝隙腐蚀性。铌元素在焊接过程中，可起到防止晶间开裂的稳定剂的作用。同时它对无机酸包括：盐酸、硝酸、磷酸和稀硫酸以及氧化还原反应的环境下，也具有良好的耐蚀性；并具备耐45.7m/s高速流动海水侵蚀的能力。
625合金的耐腐蚀性非常优秀，特别是在中度腐蚀的环境中，如淡水和海水、中性盐及碱性溶液中，是几乎不发生腐蚀的。不论是在泥土掩埋，飞浪区还是在流动的海水环境中，在18个月的测试期限内几乎不发生腐蚀。
金属拉拔是一种古老的加工方法用途广泛，简单适用。它是通过模具孔减少加工材料的截面，获得高精度、高光泽度的管材和棒(丝)材的一种塑性加工工艺。拉拔通常是冷加工过程，是一种连续和稳定的工艺。由于拉拔过程中的摩擦热和模具磨损以及工件的表面质量要求，需要使用拉拔润滑剂进行润滑和冷却。拉拔润滑剂可降低拉拔应力和能耗，减少模具拉裂和保持较低的拉拔温度。选择适当的润滑剂，能保持拉拔过程的润滑膜对产品的表面光洁度有很大的影响。
对金属坯料施以拉力，使之通过模孔以获得与模孔截面尺寸相同的制品的塑性加工方法称为拉拔。大量的棒材、丝材和管材是采用拉拔工艺生产的，而摩擦在拉拔工艺中起着关键性的作用。选择相应的润滑剂是根据摩擦特性和冷却能力。流体润滑是拉拔中最为理想的润滑状态，能大大降低摩擦系数和摩擦表面温度，不发生磨损和粘结损伤，提高模具寿命和制品的表面质量。润滑剂要求具有良好的粘附性、耐温性、耐压性、能形成稳定的润滑膜，起到润滑和冷却的作用，拉拔后润滑膜易于清除，减少动力消耗，改善加工金属表面的质量和公差，提高光洁度。
