They’re considered precious metals and have been used as currency (a store of value).

These metals occur worldwide, but not in large enough quantities to render them less valuable.

In addition to noble metal properties, gold, silver, and platinum posses the following characteristics: This group includes the following elements: ruthenium, rhodium, palladium, osmium, iridium, gold, silver, and platinum. They also possess varying degrees of resistance to acids.

Non-Silver Jewelry Metals with Silver NamesĬhemically, noble metals resist oxidation and corrosion in moist air.

The ion plating process was first described in the technical literature by Donald M. Uniformity of plating not always consistent.Increased variables to take into account when compared to other techniques.Improved chemical reactions when supplying plasma and energy to surface of the bombarding species.Flexibility with the level of ion bombardment.More energy available on the surface of the bombarding species, resulting in more complete bonding.

Better surface coverage than other methods ( Physical vapor deposition, Sputter deposition).Ion plating is used to deposit hard coatings of compound materials on tools, adherent metal coatings, optical coatings with high densities, and conformal coatings on complex surfaces. By using a reactive gas or vapor in the plasma, films of compound materials can be deposited.

The latter ion plating configuration is often called Ion Beam Assisted Deposition (IBAD). Ion plating can be done in a plasma environment where ions for bombardment are extracted from the plasma or it may be done in a vacuum environment where ions for bombardment are formed in a separate ion gun. The energetic particles used for bombardment are usually ions of an inert or reactive gas, or, in some cases, ions of the condensing film material ("film ions"). The depositing material may be vaporized either by evaporation, sputtering (bias sputtering), arc vaporization or by decomposition of a chemical vapor precursor chemical vapor deposition (CVD). In ion plating the energy, flux and mass of the bombarding species along with the ratio of bombarding particles to depositing particles are important processing variables.
