Corrosion, Corrosion, Corrosion

Corrosion occurs from when materials (frequently metals) chemically react with their environment. It is a natural process that converts refined metals to their more stable oxide.

However, there are protection methods that can be put in place to protect your metals from corroding. The following are the classification of corrosion protection methods.

Active corrosion protection

The goal of active corrosion protection is to influence the reactions that happen when a metal corrodes. It is able to control the package contents and the corrosive agent as well as the initial reaction itself which may be able to avoid any corrosion.

Passive corrosion protection

During this method of corrosion protection, the damage is prevented through mechanical isolation of the package contents from any aggressive corrosive agents which can be done through protective layers, films or any other coatings. Sometimes, passive corrosion protection will change neither the general ability of the package contents to corrode, nor how aggressive the corrosion agent is.

Permanent corrosion protection

The main purpose of permanent corrosion protection methods is to provide protection where it is being used. The stresses presented by climatic, biotic and chemical factors will be slim in this situation. Machines will often be found in factory sheds, which are protected from extreme variations in temperature – this is often the cause of condensation.

Polish Craft offer hard chrome plating and metal polishing services to renew your metals and rid them of corrosion!

Advantages of chromium plating

Chromium plating, otherwise know as chrome plating, uses the technique of electroplating a fairly thin layer of chromium onto a plastic or metal surface.

It is possible for the layer to be for purely decorative purposes, as well as it being able to provide resistance against corrosion, make cleaning efforts simpler, even to make a surface resilient. There are a variety of imitations of chrome that are inexpensive used solely for aesthetic purposes.

There a number of advantages that present themselves with chromium plating:

  • Great surface finish
  • Rare to little rusting
  • Aesthetics

What is hard chrome plating?

Hard chrome plating is the term given to the electroplating process where chromium is distributed from a chromic acid solution.

Hard Chrome PlatingThere are a variety of types of hard chrome which include porous chromium, micro-porous chromium, crack free chromium and micro-cracked chromium.

The micro-cracked coatings and porous coatings must acquire a minimum thickness between 80 and 120┬Ám in order for them to confer adequate corrosion resistance. These platings are designed to retain lubricant which is used for sliding and bearing types of applications.

Chrome plating is the solution for resisting wear and corrosion along with its tribological (low friction) characteristics.

Polishcraft’s metal polishing

Polishcraft initially began as a polish only service in 1983 giving us plenty of time to perfect our technique over the years.

For those that are unaware of what metal polishing entails; it is simply the name given to plated and solid items that have been cleaned and stored to achieve a shiny and smooth surface.

The metals that can have polishing include:

– Aluminium
– Chrome
– Copper
– Gold
– Nickel
– Silver

Polishing can be done through a variety of tools which include buffers & polishers, acids, solvents and more.

Types of metal polish

– Aluminium and stainless steel will oxidise on the surface acting as a protector from corrosion – we proceed to remove the oxidisation and smooth it down to achieve a shiny finish much like chrome.

– Metal polishing for chrome is slightly different as it isn’t polished but cleaned. Because chrome doesn’t oxidise as much as other metals, it is unnecessary to polish.

– If metals are pitted or scratched, it is best to smooth the metal prior polishing. To smooth a metal, use wet dry paper or wet sand.

– The metal polishing will finish with buffing which is done by a rotating wheel that will hold a buffing compound that could potentially contain a mixture of wax and/or fine abrasives.

Our metal polishing in Birmingham offers a joint service of polishing and hard chrome plating as well as just polishing.
