| Popis: | We have developed and tested a new method for the one-stage application of two-component boronchromium coatings on steels in the lithium melt–chromium oxide–boron medium. We have established the mechanism of coating formation: first, the transport melt is enriched with chromium, reduced from its oxide, and afterwards boron powder is dissolved. Therefore, a chromium coating is first formed on steel, and then it is alloyed with boron. The method of one-stage boron-chromizing from lithium enables one to decrease the time of coating formation by a factor of 2–3 as compared with the step-by-step method. |
