Electroless Nickel Plating Glossary
Electroless nickel plating is an auto-catalytic reaction used to deposit a coating of nickel on a substrate. Unlike electroplating, it is not necessary to pass an electric current through the solution to form a deposit. This plating technique is to prevent corrosion and wear. EN techniques can also be used to manufacture composite coatings by suspending powder in the bath.
Electroless nickel plating has several advantages versus electroplating. Free from flux-....
Anodising Glossary
Anodising is extensively used for the production of protective and decorative films on aluminium. The most widely used processes for preventing oxidation of aluminium are based on sulphuric acid and chromic acid.Hard Anodising
Hard anodising is mainly applied to components for the production of hard wear-resistant surfaces on aluminium for the aerospace industry and general engineering uses.
The coating has exceptional wear resistance and excellent mechanical strength. Hard an....
Cadmium Plating GlossaryCadmium Plating
The demand for cadmium plated components has risen very recently, and is mainly applied to components for the aerospace industry.
Cadmium plating gives a silvery white metallic appearance with excellent corrosion resistance. The metal is also reasonably hard and very ductile therefore making it useful as a coating for work which requires flexibility. The coating is electropositive to iron and has a very low contact potential with aluminium. Cadmium is a co....
Chemical Black Plating Glossary
EIC Finishing Services can offer two types of chemical black:
Chemical black on copper or copper plated articles
This is a non-electrolytic process which provides a very adherent coating with a jet black finish. The finish itself will withstand temperatures up to approximately 200°C. The chemical blackening gives good corrosion resistance to salt spray on copper based alloys. This protection can be greatly improved by immersing the components in oil, lacquer o....
Chrome Plating GlossaryNickel/Chromium
Bright Chromium does not exist in its own right. A deposit of nickel is required prior to any chromium application. If used without the combination of nickel, an extremely heavy deposit of chromium would need to be applied in order to achieve only a slight degree of protection against corrosion and wear.
Experience has shown over the years that a nickel/chromium finish provides the best protection against abrasion, and corrosion, whilst providing a finish t....
Copper Plating Glossary
Copper is a relatively soft and ductile metal which has excellent electrical and thermal conductivity. Copper may be deposited either as a bright or dull coating and it is widely used for both decorative and industrial purposes.
Because the electrical conductivity of copper is good, it is an important finish within the electronic and electrical industry. Copper is also widely used as a stopping off material in the case hardening process.
Acid Copper
The main applications ....
Phosphating Glossary
Phosphating can be used for a wide range of applications within the manufacturing industry. There are four main areas of use for phosphate treatment:
Pretreatment before painting due to its high porosity into which the paint can key.
Protection against corrosion when used in conjunction with an oil seal.
Anti wear - Phosphate coatings can be used as efficient lubricant carrier, providing resistance to wear and are particularly advantageous on sliding surfaces.
Phosphate coat....
Silver Plating Glossary
Silver in its purest form is a soft, white, lustrous metal which is extremely malleable and ductile and capable of taking a high polish. It may be electrodeposited in either a soft dull finish or a hard semi-bright finish, suitable for use in the aerospace industry and the electronic and electrical industries. The two types of finishes available are:
Semi-Bright Silver
Semi-bright silver posseses certain qualities which make it particularly suitable for use in many aerosp....
Gold Plating Glossary
Gold plating is a method of depositing a thin layer of gold onto the surface of another metal, most often copper or silver (to make silver-gilt), by chemical or electrochemical means. is a method of depositing a thin layer of gold onto the surface of another metal, most often copper or silver (to make silver-gilt), by chemical or electrochemical means.
Gold plating is often used in electronics, to provide a corrosion-resistant electrically conductive layer on copper, typica....
Zinc plating
Zinc coatings prevent oxidation of the protected metal by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not cause a breakdown of the substrate's surface integrity as it is formed. Indeed the zinc oxide, if undisturbed, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers. Zinc plating is th....
