Elongation and cracking testing and optical characterization of small-size coatings and materials

摘要

This invention relates to methods for testing elongation and cracking of coating arrays. The method includes simultaneously applying an elongating force to each of a plurality of coatings, and monitoring the cracks and thickness decrease in each coating. A relative performance characteristic of each coating is then determined based on a correlation between a detected crack and/or thickness decrease in the coating, and the corresponding elongating force.
