PROCESS OF DETERMINATION OF MICROHARDNESS ON MICROSECTION Russian patent published in 1996 - IPC

Abstract RU 2066861 C1

FIELD: mechanical engineering. SUBSTANCE: process relates to manufacture of cutting and other tools. Groove is made in microsection by scratching perpendicular to edge. Width of groove is measured at distance from edge with allowance for shelf of edge and half-width of groove determined on boundary of shelf. Process is realized with the use of standard hardness tester. EFFECT: improved reliability of process. 2 cl, 3 dwg, 3 tbl
