P., Registration Date 12-02-2003 Organization I.N.Frantsevich Institute for Probmens of Materials Sciences Ukrainian Academy of Science popup.description2 It have been established of regularity formation the intermetallide layers of TiCr2, ZrCr2, HfCr2 on diffusion zone wich are function from structure component diffusion pairs. Elaborated methods of receiving of intermetallides have permited to define the mechanical properties and the thermal expansion coeficient at wide temperature interval. It have been determined that strenght amount to 650 MPa at 1373 K. However, at the further raising temperature it decreases quialy and it is 136 MPa at 1573 K. It have been shown peculiarities of oxidation of TiCr2, ZrCr2 and HfCr2 intermetallides. It have been established oxide-firms forming, making from them complex compounds and influence of rhis processes at the oxidation. It have been established the TiCr2 and ZrCr2 intermetallides has higher corrosion-electrochemical properties as compared with chromium. ZrCr2 has corrosion resistant hear one noble metals after catodic and intensive anodic polyrisation. Product Description popup.authors popup.nrat_date 2020-04-02 Close
