Metals finishingSurface metal finishing adds value to products by making them last longer, look better or perform in ways that would otherwise be impossible, because of the flexibility and resistance to wear and corrosion.

To overcome these metal finishing issues, metallic coatings are applied to the bare metal, to enhance appearance and ensure long in-service life. Typically Gold, Silver, Chromium, Copper, Nickel, Tin and Zinc are used for the coating and can be applied to a vast number of surfaces, both metal and non-metal alike.

Chrome is often thinly coated onto metal to provide both corrosion resistance and a decorative finish in automotive trims and bathroom accessories, whereas Titanium is coated on steel in high speed tool drills. Zinc coating is applied to a metal surface to prevent oxidation to ensure long in-service of items like fasteners, nuts, bolts, etc..

Metal finishing and coating analysis with XRF

X-ray Fluorescence (XRF) spectrometry is highly suited for metal plating analysis because X-rays achieve higher penetration depths than comparable techniques. Coatings are composed from a variety of metallic mixtures and compounds all of which must be analysed for the correct chemical composition, or to ensure the coating thickness meets quality control requirements.

Coating thickness measurement and metal finishing

Coatings can be applied as single or multiple layers, providing different properties to the original component. Careful control of the layers thickness and uniformity is important to ensure products specifications are met, and production costs are tightly controlled.

 Coating thickness measurement can be done by:

  • Thickness Measurement Gauges: based on magnetic induction or Eddy Current technology for Anodising, Electrodeless Nickel Plating, Galvanising, Plating, Powder Coating
  • X-ray fluorescence (XRF) analysers
    • Benchtop X-ray fluorescence (XRF) analysers: X-Strata920, Eco, Compact and Maxxi range for the rapid, non-destructive coating thickness and composition analysis of single and multiple metallic coating layers on a wide variety of surface. Our benchtop analysers can analyse components of various sizes, down to 0.15mm
    • Handheld XRF analysers: because of their small size and light weight (1.5kg), the X-MET8000 Series analysers are ideal for the rapid, non-destructive analysis of single-layer coating thickness on large and/or heavy parts. Rugged and easy to use, the X-MET can be used for incoming inspection, as well as on the shop floor for process control.

These analysers for the metal finishing and plating industry are cost-effective production and quality control tools, enabling increased productivity (fewer component rejects), and helping to minimise production costs (less material usage and wastage).
