Taguchi Approach to Optimize Pack Aluminization Parameters in Carbon Steel Using MINITAB13 [PDF]

Engineering and Technology Journal, 2009
Pack aluminization has been rapidly developed and widely used in many fieldsdue to its superior properties of coating. Surface is the only part of the componentwhich has to coexist with external environment. Majority of engineering failuresoriginate from

Aluminizing by pack cementation to protect CoSb3 from oxidation

Materials Chemistry and Physics, 2020
Abstract The CoSb3 skutterudite compounds are thermoelectric materials used to produce electricity from heat. Unfortunately, these materials quickly oxidize in air at elevated temperature. To solve this problem, this work explores the possibility to produce a protective aluminide surface layer to limit the interactions with oxygen.

Microsphere Autolithography—A Scalable Approach for Arbitrary Patterning of Dielectric Spheres

Advanced Functional Materials, EarlyView.
MicroSphere Autolithography (µSAL) enables scalable fabrication of patchy particles with customizable surface motifs. Focusing light through dielectric microspheres creates well defined, tunable patches via a conformal poly(dopamine) photoresist. Nearly arbitrary surface patterns can be achieved, with the resolution set by the index contrast between ...

Growth Kinetics of a Silicon-Modified Aluminide Coating on a TiNM-B1 Intermetallic Alloy

Advances in Mechanical and Materials Engineering
TiAl-based intermetallic alloys are used as a structural material in high-temperature applications such as aircraft and turbine engines. To improve the mechanical properties of TiAl, it is often modified by adding other elements such as niobium or ...

Predicting Atomic Charges in MOFs by Topological Charge Equilibration

Advanced Functional Materials, EarlyView.
An atomic charge prediction method is presented that is able to accurately reproduce ab‐initio‐derived reference charges for a large number of metal–organic frameworks. Based on a topological charge equilibration scheme, static charges that fulfill overall neutrality are quickly generated.

Micro and Nanostructural Diversity of Lizard Osteoderm Capping Tissue in Relation to Mechanical Performance

Advanced Functional Materials, EarlyView.
This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.

Multipurpose Transparent Nanocomposites for Gamma Spectroscopy, Pulse Shape Discrimination, Thermal Neutron Detection, Radiation Shielding, and High Refractive Index Applications

Advanced Functional Materials, EarlyView.
Materials exist that are useful for gamma scintillation, radiation shielding, neutron‐gamma pulse shape discrimination (PSD), thermal neutron detection, or high refractive index applications. While certain materials have exhibited optimal performance for each of these applications, none achieve multiple functions.
