Adding Metal Coatings Into The Mix

When industries add metal coatings into the mix, they are adding a solid continuous film, as an example, to prevent corrosion. Coatings can be applied to the surface of plastic, fabric, or metal, and have many uses. Some uses include decoration, insulation, and protection. For the components and parts to which they are applied, coatings of this sort allow them to last longer by making them more durable.

But what kinds of metal coatings exist and how do they make a difference? Also, who makes use of the various metal coatings?

Conversion Coatings or Electroless Coatings

This coating helps improve corrosion protection and refers to coatings generated from black oxide and other conversion processes. The formation of rust is obstructed by a blacking solution which is a result of the oxidation process for metals. A micro porous surface is then developed.

Ion Plating

A good method to create this coating is with thermal evaporation. The production of this coating involves processes such as implantation, ion and atom sputtering, thermal evaporation, and electroplating.

Galvanized Coating or Zinc Coating

When it comes to metal coatings, this is one of the most popular and commonly used. Designed to control corrosion, frequently, it is the chosen coating for carbon steel. To get the desired coating, the metal is immersed into melted zinc – a process achieved by hot dip galvanization. When it comes to oxidation, zinc is an excellent deterrent. Thanks to galvanic action, even if abrasions happen, the surface is still protected. In this manner, the surface on edges and around holes is kept well protected.

 Aluminum Coatings

Available for these coatings are hot pure aluminum or hot dipped aluminum silicon. Excellent resistance and protection against corrosion are offered by both. This is the perfect coating for shield, automotive, and heat panel applications. The reason for this is that the coating has a heat reflectivity of 900°F and a heat resistance of 1250°F. Additionally, against atmospheric corrosion, it has longer lasting protection. This makes it perfect for applications such as the optoelectronic, medical, aerospace, and automotive industries.

Why Use Metal Coatings?

With these specific types of coating, parts and components can be protected from oxidation, physical barriers, and corrosion. What does that mean for your industry? It means that, potentially, you can cut down on manufacturing expenses, save on premature replacement costs, and provide durable performance. Surely, your business could benefit from not only cost savings, but longer-lasting performance, through the use of metal coatings.

The Application of Metal Coatings

The specific surface to which the metal coating will be sprayed, must, before the spraying process begins, be pre-cleaned and roughened. There are virtually no limitations to the size or shape of the equipment or parts to be sprayed (coated). A good metal or alloy coating can be obtained according to the requirements of the industry in question.
