Functional Coatings

Conformity over complex 3D surfaces

Chemical vapor deposition (CVD) is a thin film  deposition technology that provides uniform, dense, high purity coatings with excellent step coverage and conformity over complex 3D surfaces. CVD reaction parameters allow for control of the coating  composition, crystallinity, defect density, and internal stresses.

Ever-improving performance for components used in a range of industries including aerospace, automotive, medical, solar power, microelectronics, and optics, among others. Functional coatings are under continuous development. CVD Equipment Corporation’s systems are used in many functional coatings applications.
