Study on Two-phase Nanocrystalline Nd8.5Fe74Co5Cu1Nb1Zr3Cr1B6.5 Permanent Magnet

Jiansen NI , Hui XU , Mingyuan ZHU , Qiang LI , Bangxin ZHOU , Yu , a DON

Nd8.5Fe74Co5Cu1Nb1Zr3Cr1B6.5 bonded magnets were prepared by melt-spun and subsequent heat treatment. Magnetic properties of Br=0.68 T, JHc=716 kA/m, (BH) max=77 kJ/m3 were achieved. The addition of Cr element shows to be significantly advantageous in reducing grain size and increasing the intrinsic...

Influence of Ar/N2 Flow Rate on Structure and Property for TaN/NbN Multilayered Coatings

Xuehua ZHANG , Yuanbin KANG , Sipeng LIU , Qiang LI , Ying YANG

材料科学技术（英文）

TaN/NbN multilayered coatings with nanoscale bilayer periods were synthesized at different Ar/N2 flow rate by r.f. magnetron sputtering. XRD and nano indenter were employed to investigate the influence of Ar/N2 flow rate on microstructure and mechanical properties of the coatings. The low-angle XRD...

Effect of Substrate Bias on Microstructure and Properties of Tetrahedral Amorphous Carbon Films

Jiaqi ZHU , Jiecai HAN , Songhe MENG , Qiang LI , Manlin TAN

材料科学技术（英文）

The microstructure and properties of tetrahedral amorphous carbon (ta-C) films deposited by the filtered cathodic vacuum arc technology has been investigated by visible Raman spectroscopy, AFM and Nano-indentor. The Raman spectra have been fitted with a single skewed Lorentzian lineshape described b...

Synthesis and Structure Transformation of Orthorhombic LiMnO2 Cathode Materials by Sol-gel Method

Shixi ZHAO , Hanxing LIU , Qiang LI , Shixi OUYANG

材料科学技术（英文）

Orthorhombic LiMnO2 cathode materials were synthesized successfully at lower temperature by sol-gel method. When LiMnO2 precursor prepared by sol-gel method was fired in air, the product was a mixture of spinel structure LiMn2O4 and rock-salt structure Li2MnO3, whereas in argon single-phase orthorho...
