anodic polarization 中文意思是什麼
-
The corrosion behavior of nanocrystalline ( nc ) copper bulks with various grain sizes prepared from igc ( inert gas condemsation ) and vacuum annealing in comparison with conventional microcrystalline ( mc ) copper ( as - rolled and electrolytic ) in acid copper sulphate solution and neutral solution containing chlorides under free corrosion conditions and anodic polarizations has been studied using potentiodynamic polarization, potentiometric analysis, cyclic voltammetry and electrochemical impedance spectroscopy. x - ray diffraction was used to estimate the grain size of the annealed nc copper. field emission gun scanning electron microscopy and x - ray energy - dispersive spectroscopy was used to characterize the surface morphology and analyze the surface composition after the polarization and potentiometric test of both nc and mc copper
本文研究了用igc （惰性氣體蒸發凝聚原位溫壓法）制備並真空退火到不同晶粒尺寸的納米晶銅和微米晶銅（冷軋紫銅、電解銅）在酸性硫酸銅溶液和中性含氯溶液中，在自腐蝕狀態和陽極極化狀態下的腐蝕性能。使用了動電勢極化、電位測定、循環伏安法（ cv ）和電化學阻抗譜（ eis ）等方法。 x -射線衍射（ xrd ）的方法用來估算納米晶銅晶粒尺寸。 -
A modified definition of polarization resistance calculated from the equivalent circuit of eis make its value dependent on the grain size. in anodic polarization test ( sweeing and stair - steps ), the maximum ( critical ) current density increases while the passivation potential and breakdown potential lowers with the reduction of the grain size. fegsem images showed the grain growth and pitting corrosion of the nc copper surface, uniform corrosion in the mc copper surface and the broken passivation layer in both surfaces
在陽極極化實驗（包括掃描法和臺階法）中，致鈍電流雖晶粒尺寸減小而增大，而致鈍電位和擊穿電位都隨著晶粒細化而降低。 fegsem照片發現了納米晶銅的晶粒長大和孔蝕，微米晶銅表面的均勻腐蝕，和兩種銅表面破碎的鈍化膜。 -

The corrosion test, performed in 5wt % salt fog or with the electrochemical calculation of anodic polarization in 50, g / g potassium chloride aqueous solution, indicates the coatings densification corresponds with their corrosion protection to uranium. the denser the coatings are, the more effective their protection to uranium is. compared with the al coatings produced at - 300v bias voltage and al _ ( 2 ) o _ ( 3 ) coatings produced with ps technique, the al coatings at - 100v and al _ ( 2 ) o _ ( 3 ) coatings with rms and to techniques are denser thus providing a better protection for uranium
電化學參數計算或鹽霧腐蝕結果表明，鍍層的緻密程度與其對鈾基體的保護性能呈現了較好的一致性：鍍層越緻密，其保護性越好，即- 100v偏壓下的鋁鍍層和rms 、 to法制備的al _ 2o _ 3鍍層；鍍層越疏鬆，其保護性越差，即- 300v偏壓下的鋁鍍層和ps法制備的al _ 2o _ 3鍍層。 -
