Surface Finish & Roughness

Background

Material surface is often critical to product function and performance. Surface finish, polish, smoothness, texture, cosmetic appearance, interaction with other materials and surfaces, and even how the surface "feels," can affect product acceptance and functionality. Controlling surface roughness, porosity, pits and dents, cracking, contamination, grain structure, and coating uniformity within specification is essential and often a leading competitive advantage.

Surfaces and Materials

ASPEX is exceptional at examining surfaces and materials. By combining high-magnification images with an impressive depth of field, the user discovers facts unobtainable with light microscopy. Furthermore, ASPEX can provide elemental compositional information, visual comparison analysis, and easy capture and comparison of variances.

Depth of Focus

Orders of magnitude improvement over an optical microscope can greatly assist in resolving features of interest.

Product Inspection

Solve production anomalies to reduce field claims and warranty costs.

Contamination

Identify micron-scale particles and determine of their source.

Micro & Macro Porosity, Pits & Dents

Examination with high depth of field reveals nucleation or contamination sources.

Cracks, Cracking, & Microfractures

Depth of field clearly illustrates cracks and permits specific feature identification and documentation.

Delaminating & Coating Failures

Binding layers are revealed clearly, allowing feature identification and documentation.

Grain Structure

Clear image facilitates product and component verification.

Surface Finish & Roughness

Causal factors are illuminated.

Feature Distribution

Identify and quantify distinguishing or desirable features.

Grain Structure

Clear image facilitates product and component verification.

Surface Finish & Roughness

Illuminates causal factors.
