摘要

OBJECTS TO RESPECT THE INVENTION ARE TOOLS WHOSE WITH SEA AND CONFIGURATION chipless. Inventive SUBSTANCES HARDENED carbonitride of general formula (M SUB QM HIGH * 1 (C sub 1-YN SUB Y) SUB 2, the composition SUMMARY IS IN THE CITY 0.5 (less or equal) Q ( LESS THAN OR EQUAL) 0.97, 0.03 (less or equal) P (LESS THAN OR EQUAL) 0.5, 0.80 (less or equal) P + Q (smaller or equal) 1 Y 0.05 (OR LESS EQUALS) AND (less or equal) 0.95 TOTAL stoichiometry Z (≥) 0.90. carbonitrides consist of at least two phases DISTRIBUTED ON SEPARATE dust, and thermodynamic equilibrium is set RELATION TO NO METALS carbon (C) and nitrogen (N) but not for the entire system. The invention as manufactured, AMONG OTHERS, hardened carbonitride SUBSTANCES, TO THE EXTENT THAT IN AN AREA OF SUFFICIENT SHORT TIME WARMING THE PROPER MIXTURE DUST, under mixed gas stream NITROGEN / hYDROGEN AND / OR GAS PRESSURE RELATIONSHIPS WITH INERT NITROGEN PARTIAL to hydrogen and / or inert gas DE 1 : 0.5 to 1: 5 A TEMPERATURES 1,800 2,000 C. THE SUBSTANCE CA carbonitride according to the invention can be used, among others, as COMPONENT OF A ceramal or layer that inhibits wear.
