Analysis of Initial Gas Media and their Influence on the Process of Diffusion Saturation

Abstract:

The work analyses gas media (activators) and their influence on the process of circular aluminizing of nickel-based heat-proof alloys of grade ZhS. The paper studies the structure and properties of coatings in ZhS alloys after circular aluminizing in initial gas media NiCl₂+NH₄Cl, AlCl₃+NH₄Cl, NiCl₂ and NH₄Cl. The analysis of the formation of gas medium in the muffle of the circulation setup allows excluding unwanted inclusions (nitrogen, aluminum oxide) and their occurrence in coatings, which lead to their embrittlement and early cracking.
