Zinc alloy

An alloy whose main component is zinc

Zinc immersion treatment

A pretreatment before electroplating a thin zinc deposit forms by immersion of aluminum in a zinc solution which prevents further oxidation of the aluminum and provides a key for the galvanic coating

Zinc-iron alloy layer

An alloy layer formed on iron and steel during hot-dip galvanizing as a result of the diffusion of atoms from the molten zinc into the work and vice versa

Zinc phosphate coating

A zinc-rich conversion coating produced by phosphating

Zinc plating

The application of a zinc coating by galvanizing or electrogalvanizing

Zinc-rich paint

Paint containing an extremely high proportion of metallic zinc dust in the dry film (about 95% by weight), applied to iron and steel as an anti-corrosive primer; the application of zinc-based primer may be regarded as a less durable form of cold galvanizing

Zincrometal

The trademark of a special type of coil-coated steel sheet with plastic and zinc dust coating, which is proving increasingly useful in automobile manufacture

Zinc spraying

A process for applying zinc coatings to iron and steel. Particles of molten zinc are sprayed on the surface to be coated; the coating metal, usually in the form of wire, is fed into a spray gun, in which it is melted by the combustion of a fuel gas, e.g., a mixture of oxygen and acetylene. The molten metal is atomized by compressed air and precipitated on the surface to be coated at high velocity

Zinc technology

• Low zinc technology

Zinc vapor deposition

(ZYD) A process in which zinc vapor is deposited in a vacuum on the pieces being worked on

Zip-tie

A plastic strap that, when threaded through its end and pulled, tightens and stays tight to affix cables or number plates to bicycles, or to securing wiring on vehicles.

Zirconia

Zirconium oxide, used in enamels and ceramic coatings

Zirconium

A metallic element. Symbol Zr; atomic number 40
