ABSTRACT

The article researches formation of ceramic coatings of zirconium dioxide (ZrO2) on the X12CrNi1810Ti steel surface after mechanical alloying. Study of coatings’ surface showed coalescence of defected coating’s particles with created subgrains and this process is more representative due to different toughness of zirconium oxide and steel. It is suggested that adhesive bond between the coating and support structure is provided by strain welding of the powder on the support structure coating. When using X-phase analysis neither diffusive mixing of coating/support structure components or formation of new compounds and phase changes was revealed. Surface contamination of the coating with carbon was found out and it was getting less towards the border between the coating and support structure. It could be due to mechanical sorption of carbon dioxide from the environment.


KEYWORDS
