Validation of Barkhausen Noise Inspection Through Chrome Plating Using Temper Etch Inspection
The part being investigated is a chrome plated slender tube made of 300M steel which has proven to be susceptible to grinding burns. The basics of the grinding, plating, and inspection procedures will be given along with evaluation of the data to include discussion on differentiating between grinding burns and residual stresses.
