Abstract

PURPOSE: To provide a defect-probing agent capable of a ready and clear defect- probing as well as recording by adding and mixing a malleability adding agent and coloring agent to a proper quantity of magnetic powder, a required volume of solvent and film forming compound and brushing this on the object to be probed.
CONSTITUTION: For probing the defect parts of iron and steel a magnetic fine powdery substance (magnetic powder) having a high magnetic permeability, e.g. pure ion having a grain size of less than 100 mesh is used, and to this a film forming material, e.g. rubber, and a required quantity of an extending agent are added, and additionally a white or yellow coloring agent and a surface-active and malleable additive, e.g. butyric acid are added and mixed togther to form a liquid defect- probing agent. The agent is brushed or sprayed on the whole surface of the object to be probed. After having dried, the solidified film on the painted surface is peeled off. This permits the magnetic powder existing on a defect part to be distinguished with the naked eye, accordingly, the defect part, its configuration and dimension are made clear.
