Abstract Scope |
Aluminum alloys have been used in the aerospace industry since the late 19th century because of their strength and light weighting ability. Among those alloys, 7xxx alloys are commonly used due to their high strength-to-weight ratio. With increased pressures to improve fuel economy of vehicles, 7xxx alloys are now being looked at for automotive applications where structural bonding is required.
This study will review bond durability data generated with 7xxx alloys, prepared using conventional processing as well as using new surface modification techniques, where significant improvements in these bond durability test results have been seen. Data comparing these modified surfaces using techniques such as XPS, TEM, SEM and electrochemical measurements will also be discussed.
In conclusion, this review will show that whilst these highly alloyed aluminum alloys may need to be treated differently to ensure good bond durability performance, they are certainly capable of meeting the performance requirement. |
