METAL COATING THICKNESS TESTING
Quality improvement with cost reduction is the aim of large MNCs and small companies. This fact is true for almost every category. In the industrial sector, as almost every metal is covered with some coating or the other, it is interesting how metal coating helps in tightening tolerances.
Metal coatings are an essential component for protecting the objects from corrosion and other damages. The correct coating makes the parts function well and for a longer period of time, reducing the cost eventually. The process can be done by using different instruments and methods but before initiating the process, it is necessary to understand the instrument being used.
The factors responsible for determining the best method to be used are type of coating, substrate material, size and shape of the object, and the cost of the object. Common methods used are magnetic, eddy current, cross-sectioning, x-ray etc.
Suitable for measuring coating thickness on steel and iron objects, this method is used to measure the thickness of a nonmagnetic coating. One out of these two principles is used: electromagnetic induction or magnetic pull off.
Suitable for measuring the coatings on non-ferrous objects, this method measures the thickness of a non-conductive coating. Most gauges now include magnetic and eddy current principles.
In this method, the object is cut open (cross-sectionally) and the thickness of the coating is then measured microscopically.
