Abstract : This session attempted to provide the DoD's view of requirements and potential areas of application for diamond-like carbon (DLC) coatings. Also included was a discussion of certain fundamental and practical issues which need to be addressed in this connection as the technology evolves. There was overall agreement on the potential significance of the technology for DoD, and the need for further discussions and planning aimed at validating and exploiting the technology. The importance was emphasized of enhancing both the mechanical and chemical durabilities of exposed optical components such as mirrors, windows and domes, especially those operating in corrosive environments such as salt spray, or impact-erosion-prone ones such as in airborne vehicles (rain, insects) and battlefield vehicles (sand). Surfaces must also stand up to repeated cleanings for use in many scenarios. Adhesion is an essential characteristic, and one should assess the potential advantages of amorphous as opposed to polycrystalline carbon coatings in this regard. Hydrogenation may reduce dangling bonds in the amorphous form. The durability provided by DLC could allow exploitation of materials like alkali halides which have excellent transparency but are too soft and/or hygroscopic for operational systems.
