Coatings cermet

Use Additive (with tungsten carbide) in making cutting tools and other parts subjected to thermal shock, arc-melting electrodes, cermets, coating dies for metal extrusion (0.2 mil film by vapor deposition). 

A program has been initiated at Northwestern University Basic Industry Research Laboratory (BIRL) to develop laser processing techniques for ceramic and cermet coatings, and to develop APS and HVOF techniques for spraying a variety of chromium oxide and molybdenum metal based systems.

Sol-gel technique has also been applied to modify the anode/electrolyte interface for SOFC running on hydrocarbon fuel [16]. ANiA SZ cermet anode was modified by coating with SDC sol within the pores of the anode. The surface modification of Ni/YSZ anode resulted in an increase of structural stability and enlargement of the TPB area, which can serve as a catalytic reaction site for oxidation of carbon or carbon monoxide. Consequently, the SDC coating on the pores of anode leads to higher stability of the cell in long-term operation due to the reduction of carbon deposition and nickel sintering.

Another application concerning the liquid-metal-cooled fast breeder reactors (LMFBR) was studied as development of advanced control rod materials for FBR (22). Fabrication tests and out-of-pile measurements were made of B4C/Cu cermet to obtain high-performance neutron absorber materials for LMFBR. A coating layer of Cu was formed on the surface of B4C/Cu powder, and then the coated B4C...
