Effects of water vapour on isothermal oxidation of chromia-forming alloys in Ar/O2 and Ar/H2 atmospheres

Fe9Cr, Fe17Cr and Fe25Cr alloys were subjected to isothermal oxidation in Ar/O2 and Ar/H2 atmosphere at 700?C as high temperature corrosion for 48h. Oxidation weight change measurement showed increasing Cr content reduced the oxidation rate.

Control of polymorphism in Al2O3 scale formed by oxidation of alumina-forming alloys

The selective oxidation of specific components in alumina-forming alloy such as CoNiCrAlY under precisely regulated oxygen partial pressures ( P O 2 ) can be used to control polymorphism in Al2O3 scale formed on the alloy. Dense, smooth ?

Influence of cerium addition on the resistance to oxidation of AM50 alloy prepared by rapid solidification

The influence of various cerium (Ce) additions and starting temperature on the resistance to oxidation of AM50 alloy prepared by rapid solidification (RS, RS-AM50 alloy) has been investigated. The Ce addition has two opposite effects on the oxide scale.

Rebar corrosion in carbonated concrete exposed to variable humidity conditions. Interpretation of Tuutti’s curve

This paper deals with the modelling of the rebar corrosion kinetics in unsaturated concrete cover. The concrete is assumed carbonated resulting in an active corrosion of steel. The corrosion kinetics is coupled with the ionic transport processes.

Kinetics inversion in isothermal oxidation of uncoated WC-based carbides between 450 and 800°C

Oxidation of uncoated WC-based carbides (hard metals) has been investigated between 450 and 800?C. An anomalous change in the oxidation behaviour has been found in the temperature range between 528 and 630?C.

Preparation and oxidation protection of CVD SiC/a-BC/SiC coatings for 3D C/SiC composites

n amorphous boron carbide (a-BC) coating was prepared by LPCVD process from BCl3?CH4?H2?Ar system. XPS result showed that the boron concentration was 15.0at.%, and carbon was 82.0at.%. One third of boron was distributed to a bonding with carbon and 37.0at.% was dissolved in graphite lattice.

Oxidation of 316 stainless steel in supercritical water

The oxide scales of 316 stainless steel (316 SS) have been examined after exposure to supercritical water (SCW) with 2.0% H2O2 for up to 250h. The exposed samples were analyzed using weight measurement, scanning electron microscopy (SEM), and X-ray diffraction analysis (XRD).

Isothermal oxidation behaviour of a gradient NiCoCrAlSiY coating deposited by arc ion plating on a Ni-based single crystal superalloy

gradient NiCoCrAlSiY coating consisting of Al-enriched outer zone and Cr-enriched internal zone was prepared using arc ion plating method and subsequent annealing treatment. Isothermal oxidations were performed at 1000?C and 1100?C in static air.

Oxidation behavior of thermal barrier coatings with HVOF and detonation-sprayed NiCrAlY bondcoats

The high-velocity oxygen-fuel (HVOF) technology was employed to deposit the bondcoat of a thermal barrier coating (TBC) system. The isothermal oxidation rate at 1100?C of the TBC system with the HVOF bondcoat is two times lower than that of the TBC system with the detonation-sprayed bondcoat.
