Tribological Behavior of Ti(C, N)-Based and Functionally Gradient Ti(C, N)-Based Cermets

Advanced Materials Research, 2010
Ti(C, N)-based cermet and functionally gradient Ti(C, N)-based cermet were prepared by vacuum sintering and post surface heat-treatment in nitrogen, respectively. Tribological behaviors of obtained cermets were comparatively studied. Dry sliding wear and cutting test were conducted against quenched medium carbon steel.

Preparation and characterization of Ti(C,N)-based nano-cermets

Ceramics International, 2014
Abstract Nowadays, preparation of nano-Ti(C,N)-based cermet of high performance remains a big challenge due to the difficulty in dispersion of nano-powder. In the paper, well dispersion of nano-powders was achieved by ultrasonic treatment, surfactant addition and pH value adjustment. The results showed that nano-powder agglomerates can be broken down

Effect of submicron Ti(C,N) on the microstructure and the mechanical properties of Ti(C,N)-based cermets

International Journal of Refractory Metals and Hard Materials, 2011
Abstract There is an increased industry demand for Ti(C,N)-based cermets with improved material properties. One of the parameters which are supposed to influence these properties is the mean particle size of the Ti(C,N) powder used. In this study the effects of a newly developed submicron Ti(C,N) powder grade on the properties of Ti(C,N)-based ...

A review on the microstructure and properties of TiC and Ti(C,N) based cermets

International Journal of Refractory Metals and Hard Materials, 2023
Cermets are widely used in various industrial applications due to their high hardness, thermal stability, thermal conductivity, exceptional mechanical properties, and oxidation resistance. However, they often have low toughness and require complex production processes.

Sintering behavior of the Ti(C,N)‐based cermets with graphite or diamond additives

International Journal of Applied Ceramic Technology, 2022
Abstract Combining DSC/TG–QMS analysis and dilatometry experiments at constant heating rates, the sintering behaviors of the Ti(C,N)‐based cermets with carbon additives were studied. It is found that the additives of diamond or graphite could promote the interactions among raw powders during solid‐state sintering.

Load-dependence of the measured hardness of Ti(C,N)-based cermets

Materials Science and Engineering: A, 2001
The Vickers hardnesses of a series of Ti(C,N)-based cermets were measured in the indentation load range from 1.47 to 40.67 N. It was found that the examined materials exhibit a reversed indentation size effect, i.e. the measured hardness increases with increasing indentation load.

The Influence of Cu on the Electrical Properties of Ti(C, N)-Based Cermets

Advanced Materials Research, 2011
Cermets Ti(C，N)80%Co(10-x)% TiC10% Cux%(wt%，x=0，1，2，3， 4， 5) were prepared by powder metallurgy method under vacuum condition at 1500°C and the effects of Cu element to the electrical resistivity and flexural strength were studied in this paper. It turns out the electrical resistivity of the samples obviously decreases with the introduction of Cu ...
