An alloy is a material composed of a metallic base and additional metal or non-metal elements. Alloys are typically created to obtain desirable material properties that otherwise are not present in the primary base material's pure form. While metals are commonly used as alloying additions, non-metals, primarily, are often used too.

It is shown that with the deposition of alloys from citrate electrolytes it is possible to obtain X-ray amorphous coatings with high rhenium content (up to 78 at% of Re). In a citrate–pyrophosphate electrolyte, the electroreduction of cobalt proceeds with a low overvoltage, so the proportion of rhenium in the coating decreases sharply (to 12 ...

For example, it is widely accepted that rhenium, which is commonly added to alloys used for single-crystal superalloy turbine blades, plays a key role in promoting creep resistance of these materials, but the reason for this so-called "rhenium-effect" remains controversial [7]. One explanation which has been put forward is that Re, which ...
