Background

Previous NATO activities relating to corrosion are AVT-140 (Corrosion Fatigue and Environmentally Assisted Cracking in Aging Military Vehicles) and AVT-137 (Corrosion and Maintenance Data Sharing), and more recently in 2014 AVT-222 (Continuing Airworthiness of Ageing Aircraft Systems) and AVT-223 (Cross-Domain Integrated System Health Management Capability). It was at that time unclear to the participants how corrosion was managed across the fleets, even though the common understanding was that corrosion management is important for fleet availability and maintenance cost control. Considering the common interests and common/similar platforms operated by NATO nations, it is deemed very useful to share the best practices on how to manage corrosion, and to discuss possible approaches to improve NATO nations’ corrosion management.

Objectives

The objectives of the workshop are to, 1) share the best practices on how corrosion is managed across the NATO nations, including diagnostic and prognostic tools and non-destructive inspection (NDI) techniques used to assess corrosion damage; and, 2) discuss the possible approaches that will allow NATO nations to improve the corrosion management. Both objectives will lead to improved corrosion maintenance strategies with lower costs and better operational availability of weapon systems.

Topics

• Corrosion assessment (non-destructive inspection, destructive inspection, diagnostic tools) • Corrosion monitoring (corrosion/environmental sensor, coating/protection degradation, coating breakdown/failure) • Corrosion prognostic tools (corrosion growth rate modeling, remaining life prediction, structural integrity assessment, probabilistic projection, evaluation and validation of tools) • Corrosion repair (cold spray, additive manufacturing) • Corrosion prevention (coating, corrosion prevention compounds/CPC) • Corrosion case studies (real examples of corrosion mechanisms or failures, repairs, and management) • Corrosion management policy (from “Find it and Fix it” to “Predict and Manage”, corrosion prevention and control program/CPCP across fleet, individual fleet/platform)
