Abstract: The industrial product like nozzle consist of magnetic nano-particles for the Ferro fluid black plays an important role under the domain of mechanical engineering applications. In this research work, Non-Destructive Testing (NDT) technique based on deposition of a Ferro fluid Black 140CM, Grey 249 and 147-A/2 is used for the defect testing of the boiler nozzle’s surface. Magnetic Particle Testing (MPT )is one of the widely used method for Ferromagnetic material because it is fast and relatively easy to apply as compared to other NDT method. The only requirement from an inspect ability stand point is that the component being inspected must be made from ferromagnetic material (iron, nickel, cobalt or some of their alloy). This method uses magnetic field and small magnetic particles to detect flow in component & obtained defects (linear or rounded indication) of the welded part must be machined with diamond cutter grinding machine till the defects removed.
