Project Title:

Low-Cost Surface Treatment for

Bonding Titanium Panels

Technical Abstract (Limit 200 words)

High speed travel requires reliable airframe

structure and low-cost fabrication technology.

Current adhesive joining methods for Ti panels are

not cost-effective. The resultant junctions are also

limited by the operating temperature under 430K

and the lack of long-term durability. This project

will develop new surface treatment processes to

create unique surface texture and chemistry for

strong and durable bonding with advanced

high-temperature adhesives. Phase I will

demonstrate the feasibility of two physicochemical

surface treatment processes to produce strong and

stable adhesive bonding for Ti panels. Phase II will

select one or two promising processes to optimize

performance, uniformity and cost effectiveness.

These surface treatment processes will be applied

to both monolithic and composite materials, and

titanium and other high-temperature metals, to

achieve a greater thermal stability of adhesive

bonding. Phase III will involve the development of

practical treatment procedures and equipment for

small-scale applications.

Potential Commercial Applications (Limit 200 words)

Physicochemical treatments are needed to prepare

stable metal surfaces for high-temperature

adhesive bonding. High performance and durable

adhesive bonding resulting from these new

processes could be used in high-temperature

aircraft and ground transportation applications. By

using little or no hazardous chemicals, these

processes could also reduce environmental

concerns associated with the use of hazardous and

toxic chemicals.
