Novel pack cementations: direct current field assisted pack cementations

International Heat Treatment and Surface Engineering, 2012
AbstractDirect 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.

Novel Pack Cementations: Alternating Current Field Enhanced Pack Cementations

Materials Performance and Characterization, 2018
Abstract Thermal chemical treatments can effectively improve the surface properties of steels to resist wear, erosion, fretting, and oxidation. Among the various types of thermo-chemical treatment, pack cementation is most often employed for diffusing boron, aluminum, chromium, or silicon into the surface of steel.

Pack cementation diffusion coatings

1996
Pack cementation is an in situ chemical vapor deposition (CVD) batch process that has been used to produce corrosion- and wear-resistant coatings on inexpensive or otherwise inadequate substrates for over 75 years [1]. The traditional pack consists of four components: the substrate or parts to be coated; the masteralloy (i.e. a powder of the element or

Aluminum Pack Cementation on Mo–Si–B Alloys

Journal of The Electrochemical Society, 2006
The application of a pack cementation coating of aluminum on Mo-rich Mo–Si–B alloys prior to oxygen exposure yields a significant improvement in the oxidation resistance over a wide temperature range (732–1372 °C). Upon exposure to oxygen, the Mo3Al8-rich layer that forms during the aluminum pack cementation treatment develops a protective Al2O3 layer ...

Composite cements: synergistic effects of particle packing and pozzolanicity

Proceedings of the Institution of Civil Engineers - Engineering Sustainability, 2022
The production of cement is a carbon dioxide-intensive process. Replacing ordinary Portland cement (OPC) with industrial by-products can bring down the carbon footprint associated with cement production. Various industrial residues are currently used as alternative cementitious materials in this regard.
