Thermal spray coating specimens should be sectioned perpendicular to their axis using a precision diamond saw with either a metal-bonded diamond wafering blade or an ultrathin aluminum oxide abrasive blade. Generally, an abrasive cuttoff blade selected to cut the substrate effectively will be the best blade for the combination of thermal spray coating and substrate. The specimen should be rigidly clamped in the vise and positioned so that the cutting blade enters the coated side and exits the substrate side, thus substantially reducing fracturing of the coating. Friable, porous, or brittle coatings to be sectioned may be vacuum impregnated with epoxy mounting compound prior to sectioning to protect the specimen. Typical sectioning parameters are:
•Speed: 2,500 to 3,500 rpm
•Applied load: 300 to 500 gf
•Lubricant: water soluble solution
