Surface coating analysis and characterization

The 6NAPSE Group supports manufacturers and carries out surface coating analysis. Our laboratory studies coatings behavior.

Increasing temperatures, more aggressive environments, vibrations, high stress levels, high pressures…Etc. These environmental stresses reduce the protective properties of a coating.

Indeed, the surface coating of a product is more and more exposed to failures such as: corrosion, wear, breakage, paint peeling, etc.

Surface coating analysis in Laboratory

In order to improve the functional properties of a surface coating of a metallic or organic product, the 6NAPSE Group supports manufacturers in their analysis, characterization and qualification.

Thanks to the expertise and equipment of the laboratories, the 6NAPSE Group is involved in all stages of the qualification of a surface coating and in various services:

• Study of the aging of materials: behavior of coatings in environmental tests
• Adhesion tests: measurement of the resistance to tearing of coatings
• Mechanical tests: application of a deformation, a scratch or an impact to a material
• Hardness tests: measurement or verification of the resistance of a coating or surface
• Characterization of coatings: search for premature failures on the surface and thickness measurement

All our equipment allows us to carry out tests according to the standards in force and/or customer specifications: RTCA DO-160 NF EN 3365, NF EN ISO 15-18-1, NF EN ISO 1520, NF EN ISO1522, NF EN ISO 2143, NF EN ISO 2409, NF EN ISO 2808, NF EN ISO 2812, NF EN ISO 2815, NF EN ISO 4624, NF EN ISO 4628, NF EN ISO 6272, NF EN ISO 6860, NF EN ISO 16276-2, NFL 16-106, etc.

Applications

• Control of the nature of a coating according to the specifications
• Control of the thickness of the coating by eddy current and by microscopic section
• Determination of the resistance of a coating following an environmental test (e.g. salt or sun spray test)
• Analysis on multilayers
• Determination of the behavior of a coating following the application of different fluids (chemical resistance)

  Realization of an adhesion test on paint by grid comb: adhesion according to the ISO2409 standard before and after immersion.

• Study of the aging of a paint in a climatic chamber: qualification for aging in temperature and humidity.
• Expertise of blistering on a metallized plastic part: overall visualization of the surface condition of a non-compliant part, detailed visualization of the surface condition (plastic part) after peeling.
• Hardness measurement of multi-layer plastic films
• Analysis of plastic coating on finished product (surface varnish, paints, etc.)
• Analysis of elemental impurities presented on the surface of materials
• Validation of aluminum grades, steel and surface deposits in aeronautics
