Growth kinetics and isothermal oxidation behavior of a Si pack cementation-coated Mo-Si-B alloy
Applied Surface Science, 2019In this study, coating-layer growth kinetics were determined to understand coating-layer growth behavior of Si pack cementation coatings on Mo-3Si-1B (wt%) alloys. When a pack powder mixture composed of Al2O3, Si and NaF was loaded in an alumina crucible

Low-temperature Formation of Aluminide Coatings on Ni-base Superalloys by Pack Cementation Process
Chinese Journal of Aeronautics, 2010 This article investigates the low-temperature formation of aluminide coatings on a Ni-base superalloy by pack cementation process. The pack cemented coatings characteristic of high density and homogeneity possess a two-layer structure.

Novel pack cementations: direct current field assisted pack cementations
International Heat Treatment and Surface Engineering, 2012AbstractDirect current field (DCF) assisted pack cementation processes are designed to overcome the problems of higher processing temperature and longer time in conventional pack cementations (CPCs). Anode and specimen as cathode are parallel with each other, and are embedded in powder agents, all of which are sealed in a stainless steel box.
