摘要:作为涂层前处理最重要的一道工序,超声清洗能将涂层产品表面油污、灰尘及氧化杂质清除,保证待镀产品表面清洁,提高膜基结合力。因此,本文研究超声波清洗机以及清洗液更换频次对PVD镀膜的AlCrSiN涂层铣刀的寿命的影响,通过两组对照实验,得出以下结论。第一,进口2CRD200全自动清洗设备比国产九槽清洗机清洗效果好,产品走刀寿命能提高24.09%。第二,使用2周以上的超声波清洗液清洗的刀具测试走刀寿命为2.91m,更换新超声波清洗液清洗的刀具测试走刀寿命为2.73m,频繁更换清洗液(两周一次)对提高产品待镀件清洁度,延长刀具走刀寿命影响不大。
Abstract: As the most important process of coating pretreatment, ultrasonic cleaning can remove oil, dust and oxidized impurities on the surface of the coated product, ensuring the surface of the product to be coated is clean, and improving the adhesion of the film base. Therefore, this article studies the impact of ultrasonic cleaning machine and cleaning fluid replacement frequency on the life of PVD-coated AlCrSiN coated milling cutters. Through two sets of comparative experiments, the following conclusions are drawn. First, the imported 2CRD200 cleaning equipment has a better cleaning effect than the domestic nine-slot cleaning machine, and the tool life of the product can be increased by 24.09%. Second, the test tool life of tools cleaned with ultrasonic cleaning fluid for more than 2 weeks is 2.91m, and the test tool life of tools cleaned with new ultrasonic cleaning fluid is 2.73m. Frequent replacement of cleaning fluid (once every two weeks) improves the product. The cleanliness of the parts to be plated has little effect on extending the tool life.

随着科学技术的高速发展,超声技术已越来越多地应用于人们的生产和生活的各个领域。从超声测距到超声检验,超声治疗和超声灭菌,广泛应用于工业、农牧业和医疗等各个行业,它已为人们所熟悉。但超声设备在表面处理行业的应用,人们还不够熟悉和了解。超声波可以对涂层工件施加非常巨大的能量,尤其适用于清除牢固地附着在基底上的污垢。然而在某些情况下,不合理使用超声波也会损伤待镀产品性质脆弱的基底材料[1-4]。
物理气相沉积(Physical Vapor Deposition,PVD)是现代制造业中发展迅速的先进制造技术,其涂层薄膜可以有效提高工模具的物理、机械性能和有效寿命。作为PVD涂层前处理中最重要的一道工序,超声清洗能将涂层产品表面油污、灰尘及氧化杂质清除,保证待镀产品表面清洁,提高膜基结合力,从而有效提升产品性能[5]。……
