摘要

A simple surface pretreatment process for Ti-6-4 alloy was developed at NASA/LaRC to meet requirements of highspeed commercial aircraft application. This process may offer both environmentally safe and durable bonding at low cost under the conditions of supersonic flight. This novel surface treatment for Ti alloy is conventionally achieved with a two-step chemical process without mechanical abrasion. In addition, it is chromium-free and has been successfully used with a sol-gel coating to afford a strong adhesive bond. It exhibits excellent durability for hot wet environments with approximately 90% retention of initial strengths. An oxide layer developed by this base treatment can be controlled by time, temperature, and concentration. The morphology and chemical composition of the oxide layer was investigated which revealed formation of aluminum oxide compounds. It is expected that this process will establish a low cost and high performance surface for not only high-speed commercial aircraft but also for other commercial applications with any metal adherend.
