چکیده

This article described the protective properties of Cr coatings with a barrier layer composed ZrO2/Cr multilayers deposited onto E110 zirconium alloy. The multilayer thickness 100, 250, and 750 nm single-layer (1.5 µm) ZrO2 were obtained by multi-cathode magnetron sputtering in Ar + O2 atmosphere. Then, cracking resistance oxidation behavior studied under conditions thermal cycling (1000 °C) air high-temperature at 1200–1400 °C water steam. role on experimental coated alloy was discussed. It shown that more quantity have higher resistance, but such types samples large amount coating spallation cycling. steam (1200–1400 demonstrated interfaces can act as source cavities formed Kirkendall mechanism results accelerating Cr–Zr interdiffusion for Cr-coated

Oscillatory exchange coupling in Fe/Cr multilayers.

First-principles calculations of the reflection probabilities for Fermi surface electrons at Cr/Fe interfaces are used to compute the strength of the oscillatory exchange coupling in Cr/Fe multilayers. These calculations show that critical spanning vectors across the N -centered ellipsoids of the Cr Fermi surface cause the long period coupling for (001), (110), and (211) interfaces. The periods...

DLC-Si Protective Coatings for Polycarbonates

In this work, a-C:H:Si (DLC-Si) films were produced onto crystalline silicon and polycarbonate substrates by the rf-PACVD technique from gaseous mixtures of CH 4 + SiH 4 and C 2 H 2 + SiH 4 . The effects of self-bias and gas composition upon mechanical and optical properties of the films were investigated. Micro-hardness, residual stress, surface roughness and refractive index measurements were...
