TRANSFORMATIONS AND MASS EFFECT IN NICKEL-CHROMIUM AND NICKEL-CHROMIUM-MOLYBDENUM STEELS.

Plasma spraying and characterization of chromium carbide – nickel chromium coatings

Chromium carbide – nickel chromium powder Cr3C2-25wt.NiCr was plasma sprayed by a water-stabilized system WSP®. A series of experiments with variable feeding distance was carried out. Basic characterization of coatings was done by XRD, SEM and light microscopy plus image analysis. Microhardness was measured on polished cross sections. The main focus of investigation was on resistances against w...

Magnetic Relaxation and Memory Effect in Nickel–Chromium Cyanide Nanoparticles

The low temperature dynamics of a magnetic nanoparticle system Ni3[Cr(CN)6]2 with an average nanoparticles size of 4 nm was studied. Using different temperature and field protocols memory phenomena were studied by the DC magnetization and magnetic relaxation measurements of the system at temperatures below Tm = 19 K. Aging experiments show an absence of any waiting time dependence in the magnet...

Shear Bond Strength of Porcelain Veneering to Nickel-Chromium, Chromium-Cobalt, Zirconia and Lithium Disilicate

Background and Aim: High chipping rates of the veneering porcelain in zirconia ce-ramic restorations have been reported in many clinical studies. However, information on the bonding behavior of veneering porcelain to zirconia and lithium disilicate frameworks is limited. The purpose of this study was to evaluate the bond-ing strength of porcelain veneering to zirconia, lithium disilicate, nicke...

A mortality study of nickel/chromium platers.

The mortality experienced by a cohort of 2689 nickel/chromium platers between 1946 and 1983 has been investigated. All members of the study cohort had some period of chrome exposed employment. Overall, compared with the general population of England and Wales, statistically significant differences relating to cancer were found for cancer of the stomach (E = 16.2, O = 25), primary cancer of the ...
