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 ...

Recent Developments in Chromium and Chromium Alloys [PDF]

open access: yesJOM, 1969
Chromium-base alloys, which have been under study now for slightly more than two decades, are attractive as potential competitors with nickel alloys for high temperature applications in advanced jet engines. Although chromium has a strength-to-density advantage over nickel, it is normally brittle at room temperature and is further embrittled by ...

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 gases on crystallization of heat-resistant chromium steels

open access: yesЛитьë и металлургия, 2023
It has been shown that the main influence on the crystallization of heat‑resistant chromium steels is hydrogen. It is a demodifying element of the casting structure.

The Performance of Different Etchants on the Carbides of Ni600 and Ni625

open access: yesMetals
Nickel-based alloys that contain chromium are widely used in corrosion-resistant applications in industry, but they are sensitive to the environment when the passive chromium oxide layer is damaged. In Ni600 and Ni625 alloys, precipitates can deplete the
