It is shown that promising materials for such coatings are thin films based on nitrides of transition metals and platinum group metals. The particular attention is paid to physical methods of obtaining high-temperature optically homogeneous coatings.

Optical media with silver and aluminum reflective coatings, which are used on most CDs, cannot provide long-term storage of the recorded information.

The chrome coating can effectively protect Zr tubes from high temperature oxidation in air for one hour.

Показано, що перспективними матеріалами для таких покриттів є тонкі плівки на основі нітридів перехідних металів і металів платинової групи. Особливу увагу приділено фізичним методам отримання високотемпературних оптично однорідних покриттів. Показано, що як відбивальні покриття для оптичних носіїв може бути використано одержані магнетронним розпиленням плівки хрому та нітридів Cr, Ti, Zr та Hf.
