Ionbond™ CVD

Ionbond™ CVD Coatings for Components Applications

One of the limitations of the PVD and PACVD technologies is their inability to promote coatings into inner surfaces, like holes and cavities with high aspect ratio. This  shortcoming can be overcome by use of CVD technology, which allows coating of ID’s of virtually unlimited length and aspect ratio. High quality coatings such as TiN, TiCN, ZrN or Al2O3 can be produced on the ID’s of various geometry, size and length. Naturally, OD coatings are possible as well.   

The CVD processing is especially friendly for austenitic (300 series) steels, which are unaffected by high temperature of the deposition process. Other materials may or may not need  re-heat treating after processing, depending on the application requirements and their composition.

In addition to the capability coat inner surfaces of components, Ionbond family of coating can provide effective solutions for protection against wear and corrosion. Notably, deposition of high quality alumina (Al2O3) coatings with high thickness by CVD processing is one of the most established ways to produce oxide films.
