... can be attained by the Brinell hardness test can be greatly influenced by the surface smoothness of the workpiece being tested. The surface of the workpiece on which the Brinell indentation is to be made must be filed, ground, machined, or polished with emery paper (3/0 emery paper is suitable) so...

... steel for several classes of microstructure. Source: Ref 5 . Loss of surface hardness generally is associated with an increased initial wear rate of the decarburized part. Also, increased tool wear could be observed in the machining of such a decarburized steel part. Because most fatigue cracks...
