Abstract:

Current magnetic particle inspections for surface and near-surface flaws in ferromagnetic parts are dependent on human observations, decisions and errors. An improvement on this would be a semi-automatic device for detection and decision making that could remove the human error. This report is concerned with the development of such a device and the determination of its feasibility. Scanning of the surface of interest is accomplished mechanically using a simple XY table and fiber optics. The signals from the fluorescent particles are detected by means of a photomultiplier tube. The problems with interfering visible light were controlled with selective optical fibers. This project has demonstrated the basic feasibility of detecting fluorescent indications. Author
