Fabricating ceramic hard thin films by vapor deposition techniques

Owing to excellent physical and mechanical properties, hard thin films are finding increasing uses in aeronautical, chemical and mechanical industry. Therefore, the filming technologies and the composition of thin films are improved continuously. In this paper, current techniques for fabricating hard thin films are reviewed. The advantages and disadvantages of the filming technologies and the effect of processing parameters on the properties of hard thin films are discussed. The current developing trends of filming technologies toward using electronic beam, ion beam and laser beam combining other filming technologies and the trends of high quality films toward multicomponent film, gradient composite film and nanocomposite film are illustrated.
