The thermodynamics calculations of renewal of tetrakhlorida silicon are conducted in the pair of toluene, and also formations of hydride of zirconium at heating in the environment of hydrogen. The calculations of gazodinamicheskikh parameters of flowing around of the covered surface parogazovoy mixture are executed in a temperature interval 1200 -1700 оС. It is shown that parogazovyy stream, flowing around the covered surface is laminarnym without konvektivnykh currents. Kinetic researches of receipt of carbide of silicon are conducted in the range of the indicated parameters. Of gas phase a method is get kondensaty of karbidkremniya on the refractory metals of W, Mo, Nb, At the temperatures of 1200 -1700 оС. Sciagraphy researches testify to cube modification of kondensatov (B-SiC). The got standards were utillized as sublimation sources at causing of karbidkremnievykh coverages on zirconium. Kavitacionnaya firmness of karbidkremnievogo coverage exceeds kavitacionnuyu firmness of zirconium. The standards of zirconium with karbidkremnievym coverage are tested in an autoclave at R = 160 atm., T=330 oС, t = 30 hours On the surface of coverage, by the probed raster microscopy, after corrosive tests it is not discovered noticeable changes.
