    摘要:

    采用真空電弧離子鍍工藝，在316L不銹鋼表面沉積鈀，鐵（Pd／Fe）合金薄膜并進(jìn)行真空擴(kuò)散熱處理，觀察擴(kuò)散熱處理工藝對Pd／Fe薄膜的形貌和相組成的影響。結(jié)果表明：采用真空電弧離子鍍工藝，可在316L不銹鋼表面沉積均勻的Pd／Fe膜；擴(kuò)散熱處理工藝對Pd／Fe膜的形貌和相組成有顯著影響。經(jīng)900℃保溫1h處理后，Pd膜與Fe膜間互擴(kuò)散形成一定量的Pd-Fe合金相；隨著熱處理溫度升高，Pd,Fe膜層向316L基體擴(kuò)散的距離增大，同時(shí)基體中的Cr，Ni向外擴(kuò)散的量也增多。

    Abstract:

    Palladium/ferrum(Pd/Fe)film was deposited on the surface of 316L stainless steel by vacuum arc deposition technique followed by vacuum heat treatment.Effects of vacuum heat treatments on the morphology and phase constitution of Pd/Fe films were investigated.The results show that Even Pd/Fe film can be deposited on the surface of 316L stainless steel by vacuum arc deposition,and the diffuse heat treatment techniques have significant effects on the morphology and phase constitution of Pd/Fe film.Certain Pd-Fe alloy phase was formed through interdiffusion between Pd film and Fe film after treatment by 900 degrees centigrade for one hour.Along with the temperature increment of the diffuse heat treatment,the diffusion distance of Pd and Fe film into the 316L matrix increase,where as amount of chromium and nickel of the matrix diffused outwards to the films also increase.
