Appearance defect of a material analysis

The 6NAPSE Group laboratory analyzes and controls the appearance defect of your materials and your products (detachment, blistering, foreign deposit, etc.).

Materials and products are used in different conditions and exposed to many multi-physical stresses during their lifetime. Thus, appearance defects may occur.

The emergence of an appearance defect on a part can also be evidence of a failure in the industrial process. It can have several impacts on the product, ranging from aesthetics to the impact on its function and can lead to many customer returns.

Thus, the analysis and control of appearance defects in the laboratory makes it possible to determine the origin of the failure.

Appearance defect analysis of a material in the laboratory

The 6NAPSE Group laboratory supports manufacturers in many cases of appearance defects and failures. Indeed, our very large fleet of equipment makes it possible to analyze the causes and origin of these faults from different characterizations.

The analysis of an appearance defect will allow us to:

• A more precise localization of the origin of the defect (detachment, blistering, foreign deposit, etc.), the determination of the impacted layers, the shape of the defect and the microscopic observation of the surface of the part.
• Analysis of the origin of the defect on the surface or in section by optical and electron microscopy, or even the depth of the defect.
• Identification of the origin of the failure and proposing solutions.
