A study of aluminide coatings on TiAl alloys by the pack cementation method
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2003 Abstract The lower case halide-activated pack cementation method was utilized to deposit aluminide coatings on TiAl alloys. Emphasis was placed on the effect of alloying elements on the aluminizing behavior of TiAl alloy. The addition of a small amount of Nb or Cr in the TiAl improved significantly the aluminizing kinetics of TiAl alloys by ...

A study on aluminide and Cr-modified aluminide coatings on TiAl alloys by pack cementation method
Surface and Coatings Technology, 2000 Abstract The halide-activated pack cementation method was utilized to deposit a suitable coating on TiAl to ensure its oxidation resistance. TiAl alloys were coated by two different pack cementation processes with simple aluminide coating and Cr-modified aluminide coating.

The codeposition of elements in diffusion coatings by the pack cementation method
Materials at High Temperatures, 1993Because of the advantageous synergistic effects of two alloying elements such as Cr and Al, or Cr and Si, in minimizing the oxidation and corrosion of steels at high temperatures, it would be beneficial to codeposit two elements into diffusion coatings at the alloy surface.

Preparation of tritium permeation barrier consisting of titanium by the pack cementation method
Surface and Coatings Technology, 2016Abstract In this work, tritium permeation barriers were prepared on the surface of super-clean reduced activation martensitic (SCRAM) steel by the pack cementation method. The pack cementation process was conducted by packing samples in a powder mixture consisting of titanium, ammonium chloride and alumina powder at 1000 °C for 30 min to form a ...

Silicon, 2021
In the current research, pack cementation method for deposition of silicide on the AISI D2 steel has been investigated. The chemical, phase composition of coatings and microstructure, were evaluated by EDS, SEM, EDS line scan and XRD techniques. Based on the results, FeSi2 phase and Fe2Si, FeSi on the surface of the deeper parts of the coatings and ...

Materials Letters, 2003
Abstract Pack cementation is a surface treatment method which has been used, during the last 50 years, for the deposition of a wide range of coatings, among them borides, onto steel substrates. Recently, a new method for the deposition of hard and/or corrosion-resistant coatings, the fluidized bed technology, has been developed.

Boron–aluminide coatings applied by pack cementation method on low-alloy steels
Materials Letters, 2002Abstract A simultaneous one-step boroaluminizing process has been performed on a 2.25Cr–Mo steel by means of pack cementation method using a B/Al boriding powder. Three distinct regions were found in the coatings consisting of an outer Al-rich layer, a transition region containing Al and Fe and an inner layer containing mostly B and Fe.

Codeposition of Elements in Diffusion Coatings by the Halide-Activated Pack Cementation Method
Metallurgical and Materials Transactions A, 1991Abstract : The codeposition of two or more elements in a halide-activated cementation pack is inherently difficult because of large differences in the thermodynamic stabilities for their volatile halides. However, through a computer-assisted analysis of the pack equilibria, combinations of suitable masteralloys and activator salts can be identified ...
