Isothermal oxidation curves of Mo-W-Cr-Pd alloys at 10 20 30 40 50 60 Time (Hours) Fig. Isothermal oxidation curves of Mo-W-Cr-Pd alloys at that the supply of chromium, which forms an outer protective Cr scale, is sufficient to eliminate any localized oxidation of molybdenum and tungsten.

An industrially viable process design is presented for the platinum catalysed oxidation of methyl α-D-glucopyranoside to 1-O-methyl α-D-glucuronic acid. In order to over-come catalyst deac-tivation due to over-oxidation, the process is operated periodically by. Strengthening Mechanisms and Oxidation Behaviour in Platinum and Platinum Alloys U.

Zeigmeister, M. Oechsle and M. Rettenmayr The chemical resistance against aggressive media even in the high temperature range and the catalytic properties qualify platinum as a material for a wide range of technical applications.

Oxidation effects on the alloy and interactions between alloy and cladding were examined, and while unprotected disks had catastrophic oxidation under dynamic oxidation at °C, the platinum cladding gave good protection from oxidation under both static and dynamic conditions for moderate times of hours at °C.

Request PDF | Influences of alloyed Si on the corrosion resistance of CoCrMo alloy to molten Al by iso-thermal oxidation in air | The corrosion resistance of Co-Cr-Mo alloys with various Si. Mo-Si-B alloys are attractive due to their high temperature mechanical properties and high melting temperature.

The oxidation of multiphase alloys develops in two distinct stages. First, there is a transient stage that corresponds to the evaporation of the volatile MoO3 and to an initial high recession rate. The steady state stage of the oxidation begins when the slower forming borosilicate.

With platinum ion plating, Ti-6Al-2Sn-4Zr-2Mo does not oxidize at ° C for a long time. When tungsten and platinum are used as the underlayer of the plating layer, the oxidation resistance temperature can be increased to °C.

Adjusting the alloy composition can also improve the oxidation resistance of the titanium material. The oxidation behaviour of a wrought NiMoCr alloy was studied under thermal cyclic conditions in air at °C for exposure periods of up to 1, h.

The morphologies, microstructures and compositions of the oxide scales were characterized by scanning electron microscopy, energy dispersive Xray spectroscopy and Xray diffraction. Effect of rhenium on the structure and properties of the weld metal of a molybdenum alloy.

Oxidation and hot corrosion studies [1,2] have been performed on such su­ peralloys. The oxidation resistance of the single crystal alloys is approximately twice that of the contemporary polycrystalline nickel-base superalloys.

The better oxidation resistance of the single crystal alloys result from the compositional differences that. Predict the oxidationcorrosion performance of structural alloys in high-temperature high-pressure sCO.

Completion Date Task - Updated Project. Of the other platinum metals, rhodium most closely resembles platinum in its behaviour at high temperature.

On platinum, the thin solid oxide film persists at temperatures up to about °C in oxygen at a pressure of 1 atmosphere (values ranging from to °C have been suggested in the literature), and perhaps up to rather lower temperatures in atmospheric air.

Cyclic oxidation behavior of aluminide, platinum modified aluminide, and MCrAlY coatings has been investigated at three temperatures. Aluminide and platinum modified coatings were deposited on GTD material using an outward diffusion process. CoCrAlY coating was applied on GTD by Electron Beam Physical Vapor Deposition (EB-PVD).

(1) Water and seawater: Titanium and its alloys are fully resistant to potable water, natural waters, and steam to temperatures in excess of °C. (2) Oxidation media: Titanium alloys are generally resistant to oxi-dizing media and oxidizing acids over a wide range of concentra-tions and temperatures.

resistance of such coatings, yet the nature of the platinum effect is still not fully understood. In this work, the oxidation behavior of two commercial NiAl and NiPtAl coatings deposited on the same Ni-base single crystal alloy CMSX-4 was analyzed. Cyclic and isothermal oxidation tests were conducted at oC in air.

Thats why we have to predict every scenario that might happen in order to avoid it. One of these scenarios is what happens to the clad and the material which have the fuel.

The Oxidation of Advanced Steel Alloys under Extreme Environments. The. The high strength and creep resistance of modern titanium alloys makes them potentially attractive for aero engine compressor blades operating at temperatures above ° C, to improve thermal efficiency and performance.

However, all these alloys suffer from oxidation at such elevated temperatures and the in-diffusing oxygen stabilizes the more brittle alpha-phase of the alloy making it prone. The approach being followed to evaluate the use of an iron-based alloy waste form to immobilize the Tc-bearing waste streams generated during the aqueous and electrochemical processing of used fuel that is being studied in the DOE Advanced.
