MEIC Metallurgy Laboratory Applications and Lab Solutions

We carry out customer service pertinent to materials identification,
coating evaluation, and corrosion assessment. Both low power and
high power microscopy are used. Metallographic examination and
scanning electron microscopy (including energy dispersive x-ray
spectroscopy) are applied, when required.
State-of-the-art Microscopy Laboratory
Scanning Electron Microscopes: SEM (with EDX) of
metallic and non-metallic materials)
3-D Optical measurement and inspection
3-D Images and profiles:
Examination of surface breaking defects, surface
finish, roughness measurement, general topography,
etc. on a diverse range of samples.
MEIC specializes in:
Coatings analysis and assessment
Coating thickness, hardness
Coating interface, Coating composition
Corrosion testing and evaluation
Material analysis identification (including structural
analysis, etc.)
Mechanical micro-hardness and macro-hardness
Failure investigations
High resolution polymer replication of materials for
in-house evaluation
Fire evaluation (e.g. steelwork to determine
damage by fire)
Failure investigations to components and for
structures of both metallic and non-metallic
materials, including work involving litigation.
Weld monitoring
Preventative maintenance
Non-destructive testing of welded joints
Use of weld polymer replication and penetrant flaw
