【摘要】:采用小多弧離子鍍制備了TiN涂層。通過金相顯微鏡、分析天平及X射線衍射(XRD)研究了有無鍍覆TiN涂層的活塞桿材料(38CrMoAl)在高溫、水蒸氣及酸性條件下的耐腐蝕性能。結(jié)果表明,200℃下兩種樣品未被氧化,400℃下38CrMoAl樣品表面氧化,而鍍有TiN薄膜的樣品表面無明顯變化,600℃下鍍有TiN涂層樣品氧化;3種腐蝕條件下,有TiN涂層的38CrMoAl活塞桿比未鍍覆涂層的活塞桿耐腐蝕性能好。
[Abstract]:TiN coatings were prepared by small multi-arc ion plating. The corrosion resistance of piston rod material (38CrMoAl) coated with or without TiN coating at high temperature, water vapor and acid conditions was studied by metallographic microscope and X-ray diffraction (XRD). The results showed that the two samples were not oxidized by 38CrMoAl at 400 鈩,
