the scientific and technological principles of metallization of products on the basis of wood with use of plasma high-temperature dispersion are developed. For the purpose of prevention of impact of the highest temperatures of a plasma stream on a front surface wood and fibrous board (fibreboard) an intermediate layer was put. The structure of an intermediate protective layer, the including mix of epoxy resin with refractory filler is developed. Operation of drawing a protective intermediate layer included several specially developed technological stages. For the subsequent metallization such non-ferrous metals as copper and aluminum in the form of a wire are used. Optimum parameters of plasma dusting of metals on a front surface of a fibreboard are determined The protective and decorative covering on the basis of non-ferrous metals had high aesthetic consumption and performance properties. The covering possessed the increased coefficient of diffusive reflection and high durability of coupling with a matrix. The dependence of influence of thickness of the raised dust metal covering on durability of coupling of a covering with a substrate is established. The developed technology of metallization of products from wood in comparison with traditional technologies, allows to lower significantly time of metallization and energy consumption and to increase competitiveness of products both on internal, and on external the markets.
An innovative energy-saving technology for producing block foam glass with a protective decorative coating has been developed, including the preliminary application of an intermediate heat resistant coating followed by the application of the main coating and the plasma jet melting. The optimal composition of the intermediate heat resistant coating, its preparation technology and laying on the front surface of the foam glass block are determined. It is shown that the main factor shaping the quality of the foam glass insulating block with a protective decorative coating is the speed of the plasma burner movement with a plasma jet on the front surface of the foam block glass with a preliminary applied two-layer heat resistant protective decorative coating. The formation regularity of the front layer texture of a protective and decorative coating on the plasma jet speed to the enclosing foam glass block has been established. It is shown that at the optimum plasma processing speed of 10 mm/s, a continuous, high-quality protective and decorative coating is formed. The features of the phase composition and microstructure of a multilayer heat resistant protective decorative coating are investigated. It is established that the surface layer is represented by an amorphous vitreous phase.
