MODEL RELEASED. Penetrant testing of metallic alloy components. This is a form of non- destructive testing in which a red dye is smeared onto the component. Excess surface dye is then wiped off and a white developer applied. This draws the red dye out of any tiny surface cracks and holes,staining the developer and allowing identification of defective areas. The test is performed on non-porous materials,usually non- magnetic metals | |
