Hardness testing is a fundamental characteristic in analyzing component properties, and, as an important materials testing tool, this critical parameter can performed and measured by a multitude of methods and techniques. While some hardness test types such the Rockwell test will yield fast, single process results based on indentation depth, many of the commonly used test types such as Vickers, Knoop, and Brinell, require a secondary process to determine the size of the indentation. These secondary processes can be time consuming, inefficient, and prone to subjective errors. One means of improving productivity while providing consistency to the process is through automatic indentation and impression reading utilizing image analysis. Dramatic improvements over the past few years in hardware, electronics, image algorithms, and software capabilities have opened the door to extremely precise and reliable testing processes that provide results more quickly than ever before. These techniques are showing great promise raising efficiency, speed, and accuracy to levels never achieved before.
