Cermets with Fe-alloy binder: A review
, 2020Raw materials supply and price, environmental safety as well as healthcare concerns have directed efforts towards development of W- and Co-free ceramic-metal composites (cermets) bonded with Fe-base alloys (steels). The aim of this review is to present a

In situ fabrication of TiC-NiCr cermets by selective laser melting
, 2020In situ synthesis of TiC-NiCr cermets during selective laser melting (SLM) was investigated. Powder mixture consisting Ti, C and Ni80Cr20 solid solution was prepared by milling process to attain the nominal composition of TiC-40 wt% NiCr.

Cermet ionomer cements are sintered metal/glass powders, which can be made to react with poly(acids). These new cements are significantly more resistant to abrasion than regular glass ionomer cements and are widely accepted as core build-up materials and lining cements.
