Quality Control of Coating Thickness
Proper quality control of coating thickness is important to the plating companies and metal finishers that are applying the coatings – but also affect the companies that utilize the plated components in their manufactured goods. Product liability requires quality control to avoid defective coatings and eliminate problems (such as rust) that can lead to production problems or product recalls. Because of this, accurate measurements of coatings are needed in the quality control process of the supply side and the incoming inspection of the receiving side.
XRF Testing of Coatings
X-ray Fluorescence (XRF) is one method of obtaining accurate coating thickness measurements. XRF analyzers provide a versatile, non-contact method to obtain measurements of thin films, single layer and multi-layer coatings on large to small components with high precision (common coatings include gold, silver, copper, nickel, tin and zinc). XRF testing equipment offers accuracy over a wide elemental range and provides simple-to-use record and report tracking to meet quality control requirements.
