Properties of TiAlCrN coatings prepared by vacuum cathodic arc ion platingRU Qiang~a HU Shejun~a HUANG Nacan~b ZHAO Lingzhi~b QIU Xiuli~c HU Xianqi~c ~a School of Physics and Communication....,Shenzhen 518053,China摘 要:<正>TiAlCrN coatings were deposited by means of vacuum cathodic arc ion plating technique on TC11(Ti-6.5Al-3.5Mo-1.5Zr-0.3Si......
. The property of plasma sprayed coatings is influenced by a large number of various parameters including feedstock, arc current, arc voltage, main gas flow rate, stand-off distance, substrate and so... of the as-sprayed coatings. The increase in arc current, arc voltage and main gas flow rate can enhance the temperature of plasma flame and accordingly lead to more sufficient melting of the injected HA......

at a bias voltage of 6 kV for 30 min prior to deposition. Composite Ti and BN plasma was generated by a pulsed cathodic arc source in the PIIID facility, and the discharge voltage and current of the cathodic arc were (22±3) V and (60±5) A, respectively. The composite plasma was guided into the processing chamber through a 90° magnetic duct. Nitrogen (N2) with a mass flow of 50 mL/min was introduced......
