Atmosphere Gas Carburizing for Improved Wear Resistance of Pure Titanium Fabricated by Additive Manufacturing

Gas and Vacuum Carburizing

The solution algorithm used in CarbTool is based on the finite difference method (FDM), and the code is developed using Microsoft Visual C++ in Window OS. The tool has been built on the concept of the carbon flux at the surface between the gas and steel is to be specified by the user. The outputs of CarbTool are the carbon concentration distribution profile inside the steel part and the surfa...

A Line-focus Transducer System for Property Characterization of Materials Fabricated by Additive Manufacturing

Effect of SiC nanoparticles addition on mechanical properties and wear resistance of cemented carbides fabricated by spark plasma sintering

WC-10Co cemented carbides containing 1 to 4 wt% SiC nanoparticles were prepared by spark plasma sintering. The effects of SiC content on microstructure, mechanical properties and wear resistance of the sintered materials were studied. Microstructural studies showed that SiC addition resulted in WC grain coarsening. In addition, the hardness decreased with increasing SiC content. However, the fr...

Thermodynamic Simulation of Gas Carburizing of Steels

      Simulation of metallurgical processes has been the subject of intense research due to the reduced number of experiments required for controlling the process as well as time and energy savings it allows. In gas carburizing of steel parts, the amount of carbon at the surface of carburized parts is the most important specification of the process in terms of achieving the desired metallurgica...
