“Multipurpose 3D Waterjet for Machining and Stripping Coatings on Weapon Systems” by Mr. Frank Campo and Mr. Mark Miller (ESTCP Project Webpage)

This ESTCP project focused on the development of an innovative process that can enable DoD to reduce or eliminate hazardous materials in its production and maintenance processes, and to ensure that alternative technologies, materials and processes are adequately vetted from an environmental perspective. The presentation demonstrated the use of the clean and environmentally friendly waterjet-based cavitation and waterjet garnet stripping process for the removal of refractory metals (including chromium) from gun barrels. The process involved successfully removing electrodeposited chromium and tantalum that have been cold sprayed onto the inside of a large caliber gun barrel. The waterjet machining process is well suited for large caliber gun barrels where water can be contained within the barrel. In addition, this process can be transferred to all caliber weapons and can also be used to precession rifle gun barrels. The benefits to the warfighter applied to all caliber weapons would be significant, as this modern process will quickly remove coatings without any reverse electroplating and with no environmental hazard exposure to the worker. The process avoids the environmental costs and time associated with reverse electroplating, as well as the cleanup of contaminated chrome solutions and chlorinated cutting oils associated with most machining operations. The presentation also provided a chronological background of prior efforts to date funded by ESTCP’s Weapons Systems and Platform program area.

 

Cold Spray Deposition of Hard Coatings for Repair and Surface Enhancement by Mr. Aaron Nardi (ESTCP Project Webpage)

Managers of critical infrastructure benefit from the situational awareness provided by remote monitoring. This information leads to improved equipment performance and reduced unplanned downtime. However, recent attacks on U.S. and international power grids and building systems highlight the need for improved security on the industrial internet of things. Relatively few manufacturers provide the majority of control systems, exacerbating the impact of distributed cyberattacks. Legacy systems often run outdated, unsupported operating systems and will never receive security patches. Firewalls and software-based security are vulnerable to compromise by hackers. 

Data diodes are security appliances that enable a physically-enforced, one-way information stream about the state of this equipment. These devices physically isolating the equipment from lower-security networks. Data diodes are used today to protect the most critical of assets but at an expense often exceeding $100,000 per connection. 

Fend’s hardware is a low-cost device that provides the one-way data transfers of data diodes while removing the need for extensive on-site configuration. On-board processors enable Fend’s hardware to communicate with protected equipment and transmit this information to an on-site network or cloud service. Fend’s diode would serve the unmet needs of critical infrastructure managers across DoD by quickly enabling secure access to equipment data. This presentation presented the results of an ESTCP-funded project designed to demonstrate the hardware’s interoperability with various equipment types, ease of installation and cost performance.
