Cr2N-7Ag self-lubricating nanocomposithinhin films were deposited on substrates made of Cr-V ledeburitic tool steel Vanadis 6 by reactive magnetron sputtering at a deposition temperature of 500 °C, using pure Cr and Ag targets, in a composite low pressure N2/Ar atmosphere.
The tip was made of polycrystalline Cr rods with a nearly square cross section of 0.7 × 0.7 mm2 obtained by cutting a 99.99% Cr foil (from Super Conductor Materials).
The material of construction of steam generator is modified 9Cr 1Mo grade steel with studs made of 1 Cr 0.5 Mo steel.
However, no statistically significant differences were observed between both types of stems in terms of ions of the metal of which cemented implants had been made of (Co, Cr, Mo, Ni) (see Table 1).

In order to allow the formation of a passivation layer protecting from reaction with liquid Al during squeeze casting, the honeycomb is made of the Cr-rich alloy commonly called "stainless-invar".
Each implant supported full-metal crowns made of Ni-Cr alloy and hybrid ceramic with standardized dimensions.
The Xience stent is made of Co-Cr L605 which is modelled as an elastic-plastic material with multilinear hardening segments based on the tensile stress-strain curve of the alloy in Figure 3a (Medtronic Technical Bulletin, 2003).
The effects of systemic metal ion exposure in patients with implants made of Co and Cr continue to be a matter of concern.
The homemade phase plate used in the current setup was an optical glass plate (surface accuracy: λ/10) with a vapor deposited circular disk made of SiO2 and Cr of diameter 200 µm arranged in the center of the optical glass plate.
