A Comparative Study on Zn and Zn-Y Coatings on 42CrMo Steel by Pack Cementation Process
International Journal of Electrochemical Science, 2017 Zn and Zn-Y coatings on 42CrMo steel were prepared by pack cementation process at 360°C, 370°C, 380°C, 390°C and 400°C for 4 h, respectively. The purpose of this work was to comparatively study the differences on the microstructure and corrosion behavior

Pack Cementation Coating For 304 & 316L Stainless Steel Alloys By Using Silicon Zing Process [PDF]
Engineering and Technology Journal, 2009 In this study, we investigated the synthesis of pack cemented coating on two metallicmaterials (304 & 316L) in order to form silicon compounds on their surface at lowertemperatures (800,900 &950˚C) to avoid sintering of the pack and adhesion of material ...

Elastic moduli of cemented sphere packs
Mechanics of Materials, 1999 Abstract We present a method for estimating the effective elastic moduli of a dense random pack of identical elastic spheres with elastic binder (cement). The cement concentration in the pore space varies from a few percent (where it fills the space at grain contacts) to 100%.

Microstructural investigation of the coatings prepared by simultaneous aluminizing and siliconizing process on γ-TiAl [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2019 In this research, formation of aluminide/silicide diffusion coatings on γ-TiAl[Ti-48Al-2Nb–2Cr (at.%)] alloy using gasphase diffusion pack cementation process has been investigated. The application of powder mixtures with various chemical compositions in

A Termite‐Inspired Alternative to Cement
Advanced Functional Materials, EarlyView.A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,
