Random iron-palladium alloys of BCC structure and containing up to 10.59 at.% of Pd have been investigated by means of 14.4keV Mössbauer spectroscopy in 57Fe at ambient temperature versus Pd concentration. It has been found that the perturbation of the iron hyperfine field caused by Pd impurity extends to the third co-ordination shell around an iron atom. Perturbations caused by single Pd atom ...

Precipitate hardening (via ordered phases rather than phase separation) of platinum and palladium can be effective even with a small volume-fraction of the ordered phase [M. Carelse, C.I. Lang, Scripta Materialia 54 (7) (2006) 1311]. The approach is particularly well suited to jewelry alloys which must be 95 wt.% pure and where ordered phases of 7:1 or 8:1 stoichiometries can be formed. We exam...

As an alternative technique for calcium phosphate coating on titanium alloys, we propose to functionalize the metal surface with anionic bath containing chlorides of palladium or silver as activators. This new deposition route has several advantages such as controlled conditions, applicability to complex shapes, no adverse effect of heating, and cost effectiveness. A mixture of hydroxyapatite a...

Abstract Developing highly efficient and durable electrocatalysts plays a central role in realizing broad range of fuel cell application. Palladium (Pd)-nonmetal nanostructures, as special class Pd-based alloys, have exhibited diversified advantages for reactions. In this minireview, the most recent progress synthesis Pd-nonmetal nanostructures their applications cells are reviewed. First, meri...

There are several benefits in using adhesive technique in removable prosthodontics as well as fixed prosthodontics. Previous studies have examined denture-base surface treatments that improve bond strength between a denture base resin and autopolymerizing repair resin. Dichloromethane and ethyl acetate are organic solvents that swell the denture base surface, thereby permitting diffusion of the...

Strength, hardness, and ductility characteristics were determined for a series of palladium-copper alloys that compositionally vary from 5 to 25 weight percent copper. Alloy specimens subjected vacuum annealing showed clear evidence solid solution strengthening. These showed, as function increasing copper content, increased yield strength, ultimate Vickers microhardness, while their was little ...

We present an ab initio study of the ternary hydride PdCuHx, a parent compound superconducting PdH, at different hydrogen content ( x=1,2). investigate its structural, electronic, dynamical, and properties, demonstrating that, low content, system is not superconductor above 1 K; however, highly hydrogenated structure strongly coupled superconductor. give solid rationale for unusual increase cri...

AIMS The aims of this study were to investigate the influence of commercially pure titanium (PTi) and titanium-aluminum-vanadium (Ti-6Al-4V) alloys (TiA) on the final shade of low-fusing porcelain bonded to them and to compare the shade changes with those of three conventional metal-ceramic systems. METHODS AND MATERIALS A titanium casting unit was used to cast PTi and Ti-6Al-4V alloy specime...
