Prediction of strong adhesion at the MoSi2/Fe interface
We report a spin-polarized periodic density functional theory investigation of the atomic structure, bonding, and ideal work of adhesion of the MoSi2/Fe interface, in order to explore the potential of MoSi2 as a protective coating for steel. We find that MoSi2 strongly adheres to Fe, with an ideal work of adhesion of 3.85 J/m for two low-index, low-strain interfaces. This value will be a lower ...
متن کاملSpectral reflectance data of a high temperature stable solar selective coating based on MoSi2–Si3N4
Data of optical performance, thermal stability and ageing are given for solar selective coatings (SSC) based on a novel MoSi2-Si3N4 absorbing composite. SSC have been prepared as multilayer stacks formed by silver as metallic infrared reflector, a double layer composite and an antireflective layer (doi: 10.1016/j.solmat.2016.04.001 [1]). Spectroscopic reflectance data corresponding to the optic...
متن کاملSTRUCTURE, BONDING, AND ADHESION OF MATERIALS INTERFACES WITH DENSITY FUNCTIONAL THEORY: Cr/Fe, SiC/Fe, MoSi2/Ni
SiC/Fe and MoSi2/Ni interfaces are investigated using first principles calculations in order to determine the structure of the interfaces and calculate ideal adhesion energies. As a baseline for comparison, calculations were also performed on the Cr/Fe interface, which shows strong adhesion, even stronger than the intrinsic adhesion of Fe. Both ceramic/metal interfaces show good adhesion. Evide...
متن کاملAnalytic environment-dependent tight-binding bond integrals: application to MoSi2.
We present the first derivation of explicit analytic expressions for the environmental dependence of the sigma, pi, and delta bond integrals within the orthogonal two-center tight-binding approximation by using the recently developed bond-order potential theory to invert the nonorthogonality matrix. We illustrate the power of this new formalism by showing that it not only captures the transfera...
متن کاملPlastic deformation of directionally solidified ingots of binary and some ternary MoSi2/Mo5Si3 eutectic composites
The high-temperature mechanical properties of directionally solidified (DS) ingots of binary and some ternary MoSi2/Mo5Si3 eutectic composites with a script lamellar structure have been investigated as a function of loading axis orientation and growth rate in a temperature range from 900 to 1500°C. These DS ingots are plastically deformed above 1000 and 1100 °C when the compression axis orienta...
