Ceramic alloy powder
| Powder | Technical Parameter | Specification | Application |
| KF-251 | HRC¡«900-1200 Working Temperature: Max. 540¡æ Cr2O3¡Ý98 |
Typical Chromium Oxide ceramic coating of corrosion resistance and wear resistance. Powder melting point is about 2400¡æ.Good density. Can be used under chemical corrosion condition below 200¡æ. | Plasma Spraying Good for textile machine parts, plunger, sealing ring, axle bush, pump impeller, fan blade. |
| KF-230 | HRC¡«600 Working Temperature: Max.1700¡æ Y2O37-8(Y2O3+ Zr2O3)©ƒ98 | Yttria Partially Stabilized Zirconia powder. Good thermal insulation ceramic coating. Resistance to thermal shock and particle erosion at high temperature. Lower thermal conductivity and good resistance to thermal shock than Aluminum oxide powder. As bonding layer mating with KF113. | Plasma Spraying Good as thermal barrier coatings for afterburners and nozzles in rocket engines and jet engines. |
| KF-240 | HRC¡«750-1100 Working Temperature: Max.1650¡æ Al2O3¡Ý99.0% |
Typical ceramic coating material. Powder melting point is about 2038¡æ. Good corrosion resistance, wear resistance and high temperature resistance. The excellent coating with grain abrasion, fretting resistance, hard surface resistance and gas erosion resistance properties. | Plasma Spraying Good for pump mechanical sealing, mud pump pluger, turbomachine blade, valve, friction parts etc. |
| KF-242 | HRC¡«60-70 Working Temperature: Max.540¡æ TiO2:40.0% Al2O3 60 |
Powder melting point is about 1840¡æ. Dense and good toughness, high bonding strength. Better anti-corrosion and fiber wear resistance properties. | Plasma Spraying Good for drive gear journal, polished jig, fluid pressure motor valve, compressor shaft etc. |
