Mechanical and wear behaviour of nanostructure TiO2–Ag coating on cobalt chromium alloys by air plasma spray and high velocity oxy-fuel

open access: yesJournal of Materials Research and Technology, 2019
Cobalt chromium alloys constitutes the base of one important group of biometallic with excellent mechanical properties. However, due to its non-bioactive and non-antimicrobial surface, cobalt chromium alloys are vulnerable to wear corrosive attack and ...

Influence of oxide films on primary water stress corrosion cracking initiation of alloy 600 [PDF]

open access: yes, 2006
In the present study alloy 600 was tested in simulated pressurised water reactor (PWR) primary water, at 360 °C, under an hydrogen partial pressure of 30 kPa. These testing conditions correspond to the maximum sensitivity of alloy 600 to crack initiation.

Cyclic oxidation resistance of rare earth oxide gel coated Fe-20Cr alloys

open access: yesMaterials Research, 2007
Rare earths (RE) have been used to increase high temperature oxidation resistance of chromium dioxide and alumina forming alloys. The RE can be added as elements (or oxides) to the alloys or applied as an oxide coating to the alloy surface. RE oxide gels,

Effect of Vacuum Hot-Press Process on the Sintered Characteristics and Mechanical Properties of a High-Density Cr-31.2 Mass% Ti Alloy [PDF]

open access: yesArchives of Metallurgy and Materials, 2018
In this study, two different compositions of submicron-structured titanium (760 nm) and micron-structured chromium (4.66 μm) powders were mixed to fabricate Cr-31.2 mass% Ti alloys by vacuum hot-press sintering.
