What is a cermet powder coating material? What are the performance characteristics?

       Cermet is an important type of coating material made of metal or alloy as binder phase and ceramic particles as reinforced hard phase after sintering, agglomeration, coating and other processes. The most commonly used are Co-WC system and NiCr-Cr3C2 system.



     Due to the addition of metal components, the bonding strength of the cermet coating and the base material increases, the cohesion strength between the ceramic particles of the coating increases, the porosity of the coating decreases, and the compactness increases, so that the cermet coating It has better mechanical properties than pure ceramic coatings, and can be used under conditions such as greater stress or fatigue, and obtain quite ideal results.
