electrochemical-marking-leading-to-failureEven during electrochemical marking, dangerous electric sparks are possible. An especially problematic issue is the fact that this can occur onvery different types of parts.Fan diskDisk of the low-pressure turbineIn disks of the depicted type, it was suspected that electricarcs may have occurred atcontact points with electrodesduring electrochemical markingof positions during assembly.In this case, there is a dangerof LCF cracks developing during operation, with burst disks the consequence.
