The effect of technological parameters of intensive electric sintering on the efficiency of inserts produced from diamond-containing composite materials in a cobalt binder

Abstract

A device and express methods to analyze operating characteristics of diamond-containing composite materials in a cobalt binder have been developed. The experimental studies of the dependence of the diamond-containing composite material tools efficiency on intensive electric sintering have been conducted under the close-to-real operation conditions. Correlation dependences between technological parameters of sintering, microstructure, physico-mechanical properties, and operating characteristics of diamond-containing composite tool materials have been established. The ranges of variations and combinations of technological parameters of sintering, which are most promising in terms of the quality of the resultant materials, have been defined. On the strength of the data obtained an improved technology has been developed of producing segments from diamond-containing composite materials to equip tools with improved operating characteristics to be used in stone working.
