The unique property of the CVD process is a very high penetration rate, that assures that everywhere on a provided surface a layer is created (even in the hair cracks). Also, on undercuts and even on more complex geometrical shapes such as metallic foams and the like. The CVD process is generally used to add an improved wear resistance, corrosion resistance or increased friction properties to a component. CVD coatings can also be used for application at a high temperature or for anti-adhesive properties. All materials that can withstand the applied process temperature can be used. Think here e.g. of different kinds of steel, glass, and even graphite.
