Fasteners may be as small as the size of a pea but have vital importance in almost every industry. They are used for fastening or tightening one component to others and help eventually in building small to big machines. This is a reason that the fasteners or bolt’s quality cannot be ignored at all. The entire machine’s functioning; its durability is dependent on the performance of every single screw. Hence, it is both important and beneficial for the manufacturers to implement strict quality inspections. The major issues that can disturb the function of a fastener are corrosive environments that can develop rust on the surface of a bolt or screw. Let us see how Salt Spray Testing Machine can help in evaluating the performance of fasteners against rust and develop the corrosion-proof products.

How Corrosion can affect the performance of Fasteners?

Corrosion or oxidation is the process of rusting the metal surface. It occurs when the oxygen in the air or water reacts with the iron molecules present in the metal surface. The Fasteners are exposed to almost every environment – air, water, moisture, humidity and can develop corrosion anywhere. As the bolts or screws are supposed to be the joints of machines that join the components together and help them stay that way for a long time, they are completely made up of the strongest metal that is iron. And something which is all iron has more to add to the corrosion process. Therefore, fasteners when exposed to a corroded environment get rusted faster than other products.

How we can produce corrosion-proof fasteners?

The only way to protect the life of a fastener is to protect them from corrosion and that can be done by coating or painting them using corrosion-resistant paint. Such kind of paint acts as a barrier between the metal surface and the oxidizing environment. They ensure that the air, moisture or water molecules don’t pass through the coating layer and starts oxidizing the iron molecules. A coating layer must be efficient enough to perform well and protect the bolts and screws eventually delivering a long-time performance of the machine.

For manufacturers, it is very important to choose the best quality coating and for the producers of paint, it is crucial to deliver a product that matches the criteria of customers.

Salt Spray Testing Machine is an advanced technology that conducts accelerated corrosion testing and can predict the number of years after which a coating will fail to protect the metal surface. The machine is designed as per international test standards and offers precise testing and inspection. It brings high-end features, precision-based digital display and allows a testing wide number of specimens.
