      Particularities of the application technology of pyrolitic aluminum coatings

      The research of the production process of aluminum coatings with the method of chemical vapor deposition of organoaluminum compounds, known as MO CVD, allowed developing of the application technology of pyrolitic aluminum coatings (PAC). The optimization of the practical parameters was achieved with the method of bifactorial experimental planning. The diagram for the experimental-industrial installation for the PAC production was developed, that may be used as the constructive basis for the designing of the industrial models of these installations.
