Military & Aerospace
Military and aerospace applications often push technologies and operating conditions to their limits. Increased reliability is more important than ever over a wider range of operational parameters (such as wider temperature ranges, increased thermal rates of change, greater ranges of vibration and longer storage in field conditions at the point of deployment).
One of the challenges most unique to military and aerospace sector is the high value of and length of service expected of these assemblies, often being 20-30 years. During the program life, components are likely to be periodically repaired, refurbished and upgraded. Therefore, the degree of re-workability of a protective coating material needs to be thoroughly evaluated as does the reliability of repair solutions.
The costs of failure, both in direct fiscal cost and especially the loss of highly trained personnel and civilian casualties are extremely high, and so it is extremely important that these applications function exactly as required, when required, for the entire duration of the program. Protective coating can be considered a reliable main mitigation solution, preventing degradation to the assembly from the external environment.
