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. Projects initiated in FY 2020 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 •COVID-19 Disinfectant Material Corrosion Compatibility testing – Understanding potential maintenance impacts resulting from disinfectant application 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. Projects initiated in FY 2021 include: •Environmentally Friendly Coating Assessment for Non-Immersed Marine Environment for structures located in coastal environments. •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 •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. Evaluating aerospace applications for Zn-Ni coatings as an alternative to Cd coatings to improve corrosion performance while reducing environmental and human safety impacts. Activities executed included: • Delivery of corrosion control and coatings training to field- and depot-level workforce • Development of computer-based corrosion prevention design, management, and sustainment training for the acquisition workforce and facilities engineers • Validation of Cost of Corrosion data for Navy Surface Ships • Technical revisions to three corrosion-related military specifications
