Evaluation of Surface Hardness Using Digital Microscope Image Analysis

Popis výsledku v původním jazyce

The most frequently used method for hardness testing is the progressive loading test. This test measures surface hardness and requires direct measurement of the indentation’s depth. However, the diameter of the impression left by an indent can also be used to determine surface hardness. The authors designed a method and have custom-written a program for measuring and evaluating surface hardness using a digital microscope and digital microscopic image analysis. The proposed procedure and software are based on the calculation of an impression’s diameter left by an indent from digital microscopic images. The evaluation procedure and the software were tested on Ti and TiN samples of biocompatible surfaces. Measurements demonstrated that the calculated hardness results were largely similar in five different operations for measuring the sample. As a result, it seems that evaluation using surface hardness measured by three test operations appears to be sufficient. The new software and procedures proposed allows for the evaluation of surface hardness in a wide range of metal surfaces, while providing credible results.
