Is any cemented carbide suitable for the TRD process?
Unfortunately it isn’t. When the TRD or CVD process is used on cemented carbide a chemical compound called “W2C” is generated under the carbide layer that makes the cemented carbide brittle. The occurrence of the W2C process and negative effect on mechanical strength would depend upon the kind of cemented carbide. It must be selected very carefully, please contact Teikuro TRD for details.
