Abstract

The paper presents a thermodynamic analysis of chemical equilibrium characteristics of Fe-Cr-Ni-Mo and Co-Cr-Ni-Mo alloys used to produce retention coatings on dentures by diffusion saturation from point sources under 0.1 MPa at 500–1500 K. It is shown that metals are transported through the gaseous phase with FeCl and FeCl2, CoCl and CoCl2, CrCl and CrCl3, NiCl and NiCl2, and MoCl3 and MoCl4 molecules. Chromium, nickel, and molybdenum in the iron-based system should be expected to be alloyed with iron and chromium transport should be expected in the cobalt-based system.
