摘　　要：钛及钛合金具有许多优异特性,已被广泛用于现代工业及国防的各个领域,但它还存在一些缺陷。为了提高其使用性能,需要在其表面进行转化膜处理。长期以来多采用毒性大的铬酸盐和氟化物等进行处理,严重污染环境。随着对环保意识的增强,环保技术得到迅速发展,并已取得良好效果。Titanium and titanium alloy possess many advantages,so have been widely used in various fields of modern industry and national defense,but they also have some shortcomings.In order to improve their application performance,conversion films are often needed on their surface.In most cases,toxic chromate,fluoride,etc.have long been used for this purpose,causing serious pollution to the environment.With the enhanced awareness of environmental protection,green environmental protection technolgies get rapid development and have obtained good results.
