Chemical Analysis and Corrosion Testing
- Performing chemical analysis of metal alloys including both ferrous and non-ferrous alloys.
- Chemical analysis involves determining the chemical constituents of metals and related materials.
- An industry leader and co-operating laboratory for qualifying Calibration Standards for Chemical Analysis.
- Our chemical laboratory processes include Spectroscopy – Optical Emission Inductively Coupled Plasma, gas analysers, wet chemical, Intercrystalline/ Intergranular Corrosion (including G28, G48 etc).
Chemical analysis provides qualitative/quantative data relating to your products and can be used to provide:
- Independent material overchecks
- Quality control
- Reverse engineering – identify specification with little or no prior data
- Failure analysis and investigations including litigation sample investigation
- Research and development
- Ability to analyse most sample sizes and forms
- Analysis can be used to determine if the material matches a required specification or as a tool to verify incoming material.
Analysis Techniques:
- Spectroscopy – Optical Emission, Inductively Coupled Plasma and Atomic Absorption
- Inert gas fusion – Oxygen, Nitrogen and Hydrogen
- Combustion analysis methods for carbon, sulphur, nitrogen and oxygen
- Classical Gravimetric, Volumetric, Photometric and other “Wet” methods
- Component Cleanliness checks – debris weight and particle size
- XRF Positive Material Identification/Alloy verification – see Ancillary NDT processes
Typical Materials that can be tested:
- Ferrous: Iron, Carbon and Alloy Steels, Stainless Steel (including Duplex Steels), Tool and High Alloy Steels, Cast Iron and SG/Ductile Iron etc.
- Non Ferrous: Aluminium and Aluminium Alloys, Copper and Copper Alloys (including Brasses and Bronzes), Titanium, Nickel Alloys, Zinc Alloys, Cobalt Alloys, Tungsten Alloys, Magnesium, Powder Metals and “White Metals” etc.
- Chemical analysis is also undertaken on some non-metallic materials including foundry sand, some plating and other surface treatment solutions.
- Corrosion testing includes Intercrystalline/Intergranular/Pitting/Crevice methods to specifications which include: BS 5903, ASTM A262, ASTM G28 Ferric Sulphate, ASTM G48 Ferric Chloride, BS EN ISO 3651-2.
