Abstract:

The overall goal was to acquire a robotic atmospheric plasma deposition system in support of DoD funded research on plasma polymerized films for use as corrosion protection coatings FA7000-14-2-20016. This work is being pursued in collaboration with Andres Bujanda of the Army Research Laboratory. Plasma enhanced chemical vapor deposition PECVD of highly crosslinked polymeric films offers a potential means to avoid the use of environmentally unfriendly chromate pretreatments and solvent-based top coats containing volatile organic compounds VOCs found in current corrosion protection systems 1,2. Furthermore, PECVD will find wider use in DoD applications if the plasma can be generated under atmospheric conditions, circumventing the need for deposition of the coatings under vacuum. The primary need is to provide a means to produce plasma polymerized coatings at atmospheric pressure which can then be evaluated and characterized as protective coatings. The new instrumentation includes capabilities to generate plasma at varying power levels and gas flow rates, to both treat surfaces and deposit films on them, to deposit films with one or two monomers at a time, and to control the motion of the plasma across the substrate. The PECVD project will develop coatings for optimizing corrosion resistance that enhance the lifetimes of DoD assets such as ships, planes, and other outdoor structures.
