Due to the excellent corrosion resistance of superalloys, most etchants work best by swabbing (use a light pressure) the specimen with cotton soaked in the etchant. Immersion etching often results in a more irregular etch response. such as Kalling's No.2 etch (left). B&W photos clearly reveal color differences.
