Titanium and titanium alloys have been extensively utilized in biomedical implants due to their excellent comprehensive mechanical properties and biocompatibility. In this study, a ZrN/Ag2O micro–nano gradient composite structure was prepared on the surface of pure Ti by multi-arc ion plating (MAIP) technique and metal vapor vacuum arc (MEVVA) ion implantation technology. This study indicated that a dramatic improvement in performance in the surface hardness (~1800 HV0.1) was attributed to the p...

Herein, NiCr was coated on γ-TiAl via the hollow cathode glow discharge, whereas yttria stabilized zirconia (YSZ) was coated on the NiCr by multi-arc ion plating. A strong bonding between the two coatings and substrate, i.e., NiCr, YSZ, and γ-TiAl occurred. However, the surface of YSZ coating displayed macroparticles of different sizes, which affected the oxidation resistance. High-temperature oxidation behavior of YSZ/NiCr coating was investigated at 850, 950, and 1050 °C. The results showed th...

The NiCr/YSZ coating was fabricated on γ-TiAl alloy by double glow plasma surface metallurgy technology and multi-arc ion plating technology. The microstructure, microhardness, bonding strength, and burn resistance of NiCr/YSZ coating were studied in detail. The results showed that the NiCr/YSZ coating was dense and homogeneous, including a duplex structure of top YSZ ceramic coating and underlying Ni-Cr bond coating. The average microhardness of NiCr/YSZ coating was raised by a factor of about ...

The machining methodologies of spiral bevel gears based on universal computer numerical control (CNC) machine tools open up a new way for the flexible and diversified machining of spiral bevel gears. In order to improve the information interrelatedness and traceability in isolated machining mode of spiral bevel gears based on universal CNC machine tools, a novel integrated design and machining mode of spiral bevel gears based on universal CNC machine tools is proposed in this paper, and the spir...
