摘要：
NiMn2O4 ceramics were successfully prepared by laser melting deposition method. The effects of the laser power on the microstructural and electrical properties of the ceramics were investigated. The average grain sizes of NiMn2O4 ceramics were in the range of 12.49-14.70 nm, and the microscopic morphology of the ceramics improves with the increase of laser power. With different laser power, the thermal constant B values of the ceramics vary from 3049.6 to 3400.7 K, and the aging coefficients of the ceramics change from 15.32 to 10.38%. The improvement in aging properties of ceramics was discussed.
