Importance of Corrosion Testing for Rigid Materials

Rigid materials like metal parts, automobile components, jewellery etc, are all coated or plated by something or else to ensure the surface is protected against the outside extreme and adverse environmental conditions. One such condition is a corrosive environment that affects the metal surfaces that has a poor coating quality. In this blog, we will get to know how an efficient salt spray testing machine can help ensure the quality of rigid materials.

What is corrosion and how does it affect the product quality?

Corrosion tests can help identify potential rot or damage to the product during its life. Corrosion can occur in most materials from polymers to ceramics, but its degradation in metals is best known. If corrosion forms on the metal surface, a colour change is known as contamination may occur, probably with an acidic atmosphere.

Corrosion pollution often occurs during transport, especially when transporting components from abroad. Shipping may take several weeks and environmental conditions in the container may vary. Hot and humid conditions accelerate the corrosion mechanism. The problem may not be visible when the items are packaged, but when they arrive at their destination, the problem is already clear.

Why does a coating manufacturer need to perform corrosion tests?

Manufacturers of different industries test many different metal products and components for corrosion and damage resistance, including, Accessories, Jewellery, wristwatches, Home goods, Metal components for shoes and fabrics, Metal plating and coatings etc.

The quality inspection is performed to alert you to possible problems that are likely to occur during the life of the product. Metal thickness and metal analysis can also be performed on metal hardware to determine their expertise. This will usually highlight any inconsistencies in the design and show whether the plating thickness of the various coatings is sufficient. A microscope is also a useful tool for examining the porosity of metallized coatings. But the life of a coating can only be told by corrosion testing.

Salt Spray Testing Machine is a highly proficient paint or coating testing machine. It delivers an accelerated version of corrosion testing using a finely distributed slat fog that artificially creates an environment that leads to corrosion and gives results of thousand years of corrosion in a few testing hours. The machine is equipped with high-end features like a digital screen that shows values of testing parameters and a design that is based on higher accuracy.
