In magnetic particle inspections, what does the use of multiple colors help to achieve?

In magnetic particle inspections, using multiple colors aids in obtaining more accurate readings of defects. Different colored magnetic particles can highlight defects more distinctly against the surface of the material being tested. This contrast helps the inspector to identify and assess the size, shape, and location of defects more effectively.

When multiple colors are used, it can allow operators to differentiate between various types of defects or varying levels of severity, leading to a clearer understanding of the integrity of the component being inspected. This specificity contributes directly to better decision-making regarding the safety and usability of the material inspected. The enhanced visibility and differentiation enabled by the colors not only clarify the findings but also contribute to a more thorough evaluation process.
