The kinetics of multilayered titanium-silicide coatings grown by the pack cementation method
Metallurgical and Materials Transactions A, 1995The halide-activated, pack cementation coating method is a viable technique for forming silicide diffusion coatings that provide oxidation resistance for titanium alloys at high temperature. In this study, growth rates were determined for the five-layered silicide coatings on commercially pure titanium grown at 950 ‡C, 1050 ‡C, and 1150 ‡C using three ...

AlN/aluminizing coating with good corrosion resistance on carbon steel was prepared by one-step powder pack method. The phase compositions were analyzed by X-Ray diffraction spectrum (XRD). The cross-sections were investigated by scanning electron microscope (SEM) equipped with an energy dispersive X-ray spectrometer (EDS). According the analysis above,

New manufacturing method for Fe-Si magnetic powders using modified pack-cementation process
Metals and Materials International, 2013This paper describes a new method for making Fe-Si magnetic powders using a pack-cementation process. It was found that Fe-Si alloy powders were formed by a reaction of the pack mixture of Fe, Si, NaF, and Al2O3 powders at 900 °C for 24 h under a hydrogen atmosphere.

Abstract Protective/conductive coatings that resist oxide scale growth and reduce chromium migration and evaporation are required to make stainless steel interconnect materials for long-term durable operation of solid oxide fuel cells (SOFCs). To accomplish this, the interconnect can be coated by special spinels for their higher conductivity. In this

In metallurgical practice the presence of a minor amount of certain elements can induce significant changes in a material's physical, mechanical and chemical properties. In this paper we present the nature, morphology and properties of protective coatings containing Cr, Al and minor amounts of a rare earth element, applied on 2.25 Cr-1 Mo low-alloy ...
