Influence of sintering techniques on the performance characteristics of steel-bonded TiC-based cermets

Abstract

This paper analyses the influence of sintering technology (temperature, gas compression during sintering) and heat treatment on the performance of an advanced TiC-based cermet developed for metalforming. The performance was evaluated by adhesive wear resistance, transverse rupture strength and microstructure studies. Optimal technology and parameters, ensuring maximum wear resistance and strength of the TiC-based (carbide) composite, are determined. The positive effect of gas compression during sintering on the performance of TiC-based cermets was revealed. Heat treatment (tempering) that causes no noticeable changes of strength and hardness results in a remarkable decrease of the adhesive wear resistance.

Influence of Pressurized Sintering on Performance of TiC-Based Cermets

“…It is concluded that similarly to WC-Co hardmetals, the sinter/HIP technology enables improvements in the strength of low-binder cermets. Similar results were obtained for TiC-FeNi cermets [13,14].…”

“…Side wear was measured by the contact method using the Mitutoyo STRATO-9-166 measuring machine as an average of five measurements. sinter/HIP and to the dependence of its parameters (temperature and gas compression during sintering) on the performance of the TiC-based cermet [14]. The main reason is that the porosity of the composites decreases.…”

“…5). The one-cycle technology is advantageous over the two-cycle one also when the one-cycle sinter/HIP and the twocycle sinter+sinter/HIP technology (both at 1430°C) are carried out [14].…”

Microstructure and Properties of TiC Steel-Bonded Carbide Used Fe/Mo Pre-Alloyed Powder as Binder

“…Carbide phase provides alloy with high strength, hardness and abrasion resistance, and steel binder phase provides alloy with the performance of heat treatment, machinability, forgeability and weldability. Therefore, the steel-bonded carbide is a new engineering material between alloy steel and cemented carbide, which are widely used in cutting tools, moulds, wear-resisting components and so on [2][3][4][5]. In this paper, a kind of TiC based high manganese steel-bonded carbide was developed.…”
