||Most of our recent
work has been in the area of environmentally compliant materials technologies,
coatings, and finishing processes.
Advanced Surface Engineering
Technologies for a Sustainable Defense – ASETSDefense
- is a Department of Defense (DoD) initiative sponsored by the Strategic
Environmental Research and Development Program (SERDP)
and the Environmental Security Technology Certification Program (ESTCP).
Its objective is to facilitate the implementation of new,
environmentally friendly technologies for surface engineering (coatings
and surface treatments) by providing ready access to background
information and technical data from research, development, test, and
evaluation efforts as well as the status of approvals and
implementations. ASETSDefense provides users with information and
assistance to improve weapons system performance and life-cycle cost
while reducing or eliminating environmental safety and occupational
health (ESOH) impacts from coatings and treatment processes that utilize
hexavalent chromium (hex chrome, Cr6+, Cr(VI), chromate, chromic acid);
coatings that contain cadmium; and coatings that contain volatile
organic compounds (VOC).
Surface Engineering Database -
with SERDP and ESTCP, ASETSDefense has developed a relational database
designed with a search capability to provide access to the available
information needed to make informed decisions on the use of alternatives
to materials and technologies for surface engineering that pose
environmental or health hazards. This information includes detailed
engineering data, background documents, and information on processes and
products that have been validated, authorized, or implemented. For more
information and to access the database,
Rowan is the data manager and coordinator for the Canadian HCAT,
maintaining coordination between the US and Canadian teams and integrating
the Canadian data on chrome replacement.
- SERDP ID Plasma
Spray Program – Rowan is the technical lead for the HCAT
effort, funded by SERDP, to develop plasma spray alternatives for
replacing chrome plating on internal diameters of landing gear,
hydraulic actuators, etc. We
also maintain collaboration with teams developing other alternatives.
- Chrome and Cadmium
Avoidance on the Joint Strike Fighter – The JSF IPT is
concerned to avoid the use of Cr and Cd on the aircraft, since its
use will lock DoD into the technology for decades.
Rowan has carried out several technology analyses of
alternatives for outer and inner diameters, and produced an extensive
data compilation to assist engineers in adapting alternatives.
- Use of Thermal
Spray as an Aerospace Chrome Alternative – This is a JSF-funded
compilation of data on the HVOF process for aerospace use –
its properties, performance, specifications, and applications.
It is a living document on CD-ROM that incorporates
referenced documents and web sites at the click of a mouse.
- Canadian Markets for HVOF as a
Chrome Replacement – This report for Industry Canada assessed the
potential market sizes and characteristics for chrome replacement in the Canadian
transportation, oil and gas, forestry, and machinery sectors.
Assistance to NRC in establishing coating initiatives
– The National Research Council of Canada has contracted with
Rowan to assist in developing market strategies, collaboration, and
teaming with Canadian and US partners in various coating programs.
This assistance includes work with the Canadian Cadmium
