Abstract
CVD diamond has a unique set of superior properties and is long recognised to be the material of choice for many applications. Because of the challenge to explain the growth mechanism, the spreading of application areas and the simple synthesis processes it became an interesting area of investigation. Spatial technology area is optimist about the real possibilities of improving the life time of some materials and by using CVD diamond in spacecraft as heat sinks, protective coating and tribological devices. At our Institutions, besides space interest, we are expanding our contribution to some near and long term applications. In this work we present the state of the art of our research and development, as an emerging technology for many applications. Emphasis will be given on CVD diamond deposition mechanism studies when halogenated gases is added to conventional mixtures. Also, investigations of the adherence and stresses between diamond films and several kinds of substrate materials like cemented carbide and silicon nitride tools, quartz, and Ti6Al4V alloy will be presented. Also, examples of some devices in development will be presented.
