X-Ray Fluorescence test equipment is required to certify the alloy content, and coating thickness of the plating. This type of non-destructive test means that the deposit thickness, and alloy content, can be quickly and accurately. It is determined at a pre-agreed point on the component.

What Are The Benefits Of Zinc Nickel Coating?

It provides an extremely high level of corrosion protection, even under high temperatures. This means it is perfect for use in the automotive industry. Its corrosion and temperature resistance make it a great choice for under bonnet applications.

The deposits are also bright, burn-free, blister free, and have brilliant adhesion characteristics. Even when it does finally start to corrode, unlike other coatings, there is very little corrosion product. Therefore, the component remains aesthetically pleasing and fully functional.

Also, it does not set up a galvanic cell when in contact with aluminium. Therefore, it is an ideal replacement for the toxic cadmium coatings used in the aerospace industry.
