Corrosion Prevention and Control Projects and Activities
Abstract
Corrosion prevention and control projects and activities are conducted in support of the support of the strategic plan to reduce the impact of corrosion on the cost and availability of DoD equipment and facilities. FY 2020 RDT&E Projects still in-progress include: •Zinc-rich Aerosol Products for Touch-up Painting of Steel Substrates – Increased efficiency of maintenance processes •Improved Surface Preparation and Coatings for Corrosion Control of Aluminum Substrates – Extending intervals between coating applications •Pressure Sensitive Adhesive Appliques for Quick Field Repair of Topcoat Damage – Improved field-level maintenance •Weld-Through Coatings for Prevention of Crevice Corrosion in Skip-Welded Joints – Service life extension for ground vehicles Support for advanced research in the areas of improving the accuracy of the algorithm for extracting corrosion information from maintenance data, aircraft structural repair using additive manufacturing, optimizing aircraft washdown intervals, corrosion sensor development, analytical corrosion prediction methods, mitigation of biologically induced corrosion, and prediction of environmentally assisted cracking was continued. FY 2021 RDT&E Projects still in-progress include: •Environmentally Friendly Coating Assessment for Non-Immersed Marine Environment for structures located in coastal environments. --Successfully Completed in FY 2022 will be implemented in facilities criteria updates. •Gentoo Coating Application to HH-60G Tail Landing Gear Yoke to reduce corrosion inspection requirements and improve the durability of the yoke between inspection cycles; improving HH-60 readiness. •Improved Landing Gear Durability for F/A-18E/F Super Hornet evaluating the application of multiple corrosion prevention technologies to improve the landing gear system to improve readiness and reduce cost. •Ship Class Topside Corrosion Control Configuration (CT3C) Implementation multiple corrosion prevention technologies to improve the improve ship operational sustainment and reduce cost --Technologies will be implemented on 2 demonstration ships in FY 2023 •Property-driven determination of acceptable criteria in MIL-DTL-46027 (weldable aluminum armor) for enhanced sustainability and readiness to evaluate the corrosion susceptibility characteristics and impact due desensitization of aluminum alloys. --Successfully completed. •Evaluating aerospace applications for Zn-Ni coatings as an alternative to Cd coatings to improve corrosion performance while reducing environmental and human safety impacts. --Effort has expanded the implementation of Zn-Ni on multiple components processed at NAVAIR Depots, reducing the overall Cd usage while improving corrosion protection. Activities executed included: • Delivery of corrosion control and coatings training to field- and depot-level workforce provided over 22 different CPC training courses to over 800 DoD workforce personnel • Posted CLM 038 Computer Based CPC Overview Training on DAU for the DAWIA Certified workforce professionals • Expanded scope of Cost of Corrosion data for Navy Surface Ships -- Identified the top 10 corrosion drivers and top 10 maintenance labor drivers • Supported the technical revisions to corrosion-related military specifications
