In this work, two different procedures to manufacture artificial burn marks were studied. A temperature controlled, robotic assisted, laser system was used to perform temperature controlled tempering marks to carburised gear wheel teeth surfaces. Also, hydrogen-oxygen flame with robotic control was used to produce artificial burn marks on the surfaces of carburised gear wheel teeth surfaces.
The aim was to analyse the suitability of thermal damages created by these two methods by comparing the BN readings of them to each other. The new, temperature controlled, laser system was found to produce uniform quality thermal damages. While the hydrogen-oxygen process was found to be more unpredictable and it needs to be controlled extremely carefully i.e. with robotic manipulation of the hydrogen-oxygen flame. The speed of the hydrogen-oxygen flame affected the RMS values greater than the other tested parameters.
