The Vacuum Carbidization of Transition Metals of Groups IV and V
The carbidization in vacuum of transition metals of groups IV and V has been investigated. A relationship has been established between the thickness of the coatings formed and the pressure, temperature, and time of impregnation; the optimum temperatures for producing dense, pore-free layers that are well bonded to the substrate have also been determined. The two-phase nature of the structure of coatings on group V metals has been demonstrated, and a proportionality has been found between the thickness of the phases and the width of the phase regions in the constitutional diagrams.
