ELECTROPLATING: Describes the process of electrodeposition of metal or alloys from suitable electrolyte solutions. The articles to be plated are connected to the cathode in an electrolyte solution, and direct current is introduced through the anode of the metal to be deposited.
BASE MATERIAL: Describes any material (metal or plastic) which needs to be coated.
CHROMATE: Describes the action of treating metal with a solution of chromium compound to produce a protective metal chromate coating.
DRY GALVANIZING: Describes a method of hot-dip galvanising in which the metal components are first immersed in a solution of flux and then dried, becoming pre-coated with a thin film of flux. The metal is then dipped in a zinc bath, to which certain metals, such as aluminium, are added to enhance fluidity, or in the case of tin, brightness.
GALVANISE: Describes the action of zinc plating by hot dipping or electrodeposition to protect from rust.
GALVANISED COATING: Describes the procedure of applying zinc or zinc-based coating by galvanising
GALVANISE DIFFERENTIALLY: Describes the procedure of obtaining different coating thicknesses on the two sides of the sheet of iron.
GALVANISING: Describes the procedure of applying zinc coatings on the surface of a metal by hot dipping or electrodeposition.
GALVANISING BATH: Describes the procedure of applying a bath for hot-dip galvanising.
GAMMA LAYER: Describes a part of a zinc-iron alloy layer by hot-dip galvanised iron and steel containing 21-28% iron.
HIGH-BUILD GALVANIZING: Describes a galvanising process during which heavy zinc coatings are applied.
HOT DIP: Describes the procedure of coating metal parts by immersion in molten metal, such as tin or zinc.
HOT-DIP ALUMINISING: Describes the deposition of aluminium coatings by hot dipping.
HOT-DIP GALVANISE: Describes the procedure of applying a zinc coating through hot dipping.
MANGANESE PHOSPHATE COATING: Describes a phosphate coating with added manganese to increase resistance to metal fatigue.
MECHANICAL PLATING: Describes a deposition of zinc on another material through a cold-peening process.
MECHANICAL SURFACE TREATMENT: Describes the production of a metal finish through grinding, brushing and polishing the surface.
METALLISE: Describes the procedure of impregnating a non-metal surface with metal, either by metal spraying or by vacuum evaporation
METAL SPRAYING: Describes coating a surface with droplets of molten metal or alloy through the use of a compressed gas stream.
METAL SUPPORT: Describes a thin corrugated strip of steel alloy rolled up into a tight coil that supports the catalyst in a catalytic converter.
NICHROME: Describes a metallic compound containing both nickel and chromium, used in making high resistance metal.
NICKEL PLATING: Describes a thin coating of nickel deposited on a surface by electrolysis.
PLATING: Describes the action of coating a material with metal using electrolysis.
POLYESTER POWDER: Describes a powder used for electrostatic powder coating.
POLYMER COATING: Describes a form of chemical coating that will prevent paint from oxidising, protecting a vehicle’s paint from prematurely fading and its bodywork from rusting.
SUBSTRATE: Describes any form of metal surface that has yet to be finished.
SYNERGETIC EFFECT: Describes the protective effect that occurs as a result of combining a metallic coating with an additional organic coating.
TINNING: Describes the procedure of coating a piece of metal with a very thin layer of solder before applying body lead to ensure that the body lead adequately covers the area to be repaired.
WET GALVANIZING: Describes a galvanising method where flux is deposited in molten form in a zinc bath, and the metal to be galvanised when lowered into the bath passes through this layer of flux.
ZINC: Describes a metallic element used in the galvanising of metals, die casting, and a variety of other applications.
ZINC IMMERSION TREATMENT: Describes a pre-treatment procedure that occurs before electroplating where a thin zinc deposit is formed due to sheet aluminium being immersed in a zinc solution preventing further oxidation of the aluminium while providing a key for the galvanic coating.
ZINC-IRON ALLOY LAYER: Describes a type of alloy layer formed on iron or steel during hot-dip galvanising as a result of the diffusion of atoms from the molten zinc into the work.
ZINC PLATING: Describes the procedure of applying a zinc coating by either galvanising or electro-galvanising.
