Numerous high-tech manufacturing sectors rely on the guidelines established in the ASTM E2109-01 document:
ASTM E2109-01 is officially titled Standard Test Methods for Determining Area Percentage Porosity in Thermal Sprayed Coatings (TSCs). The standard was first issued in 2001 by ASTM International and is maintained by Committee E04 on Metallography. astm e2109-01 pdf
The test relies on from a polished cross-section; however, users must be trained to distinguish between actual pores and other features like oxides. How to Access the Standard How to Access the Standard Pores smaller than
Pores smaller than the resolution of the optical system cannot be measured. or semi-quantitative evaluations.
This method places a digital grid of parallel lines over the microstructural image.
Quick, qualitative, or semi-quantitative evaluations. 3. Method B: Automated Image Analysis
Evaluating porosity via ASTM E2109-01 is crucial for several reasons:
