DEFORMING TOOL, METHOD FOR ITS MANUFACTURE AND METHOD FOR ITS RECONDITIONING Russian patent published in 1995 - IPC

Abstract RU 2027550 C1

FIELD: metal working. SUBSTANCE: deforming tool has base made of titanium carbide TiC0,45-TiC0,55, and working part in form of layer of titanium carbide TiC0,8-TiC0,96 whose thickness equals 2·10-4-0,15 of thickness of tool base. Tool is manufactured by heating blank of titanium carbide TiC0,45-TiC0,55 in contact with carbon at temperature of 0.6-0.95 of melting temperature of base material for 40 min - 260 h. Base may be shaped by plastic deformation at 800-1150 C with deformation rate of 0.1-50 mm/min. Tool is reconditioned by removal of warn part, plastic deformation at said conditions and impregnation of working part with carbon by annealing at said conditions. EFFECT: higher efficiency. 5 cl, 4 tbl
