摘要: 
The electrolytic deposition of ZrO2 coatings on brass alloy was conducted in an aqueous solution of ZrO(NO3)2. The better condition of ZrO2 coatings on brass alloy was determined by controlling different electrochemical parameter and different sintering conditions; and its characterization was conducted by using Potentiostat spectroscopy, SEM/EDS, XRD and scratch testing.
The X-ray diffraction(XRD) diagrams showed that the Zr(OH)4 gel was transformed into monoclinic at 400℃ of annealing. The results of this experimentation indicate that there are most influence with anticorrosive of the thin film surface condition. However, the mold cracks were also increasing with increasing thickness and phase transformed of the thin film was reducing the corrosion resistance. The results of this experimentation indicate, specimens deposited ZrO2 for 300 sec annealing at 350℃ showed the better corrosion resistance.
By referring to the immerse testing and the liberation of metal ion analysis, through electrolytic deposition of ZrO2 coating on brass alloy, it reduce the liberation of lead ion by 50%, also reduce others liberation of metal ion. Besides, the results of scratch testing also indicate the adhesive of the coating on the brass alloys are greater than the yield-strength of the alloy.

本研究以一般黃銅合金為基材,利用電解沉積法,由硝酸氧化鋯水溶液沉積氫氧化鋯膠體於基材上。藉由控制不同的電化學參數,和不同的燒結條件後,決定適當的鍍膜條件,並利用恆定電位儀、SEM/EDS、XRD及刮痕試驗機,探討氧化鋯薄膜性質。
經由XRD分析,發現由此法所製備的氧化鋯在400℃燒結時為monoclinic的結晶相。實驗結果顯示,薄膜表面狀態對抗蝕性有極大的影響,厚度太厚時,薄膜會發生龜裂現象,薄膜相變化也會造成膜的龜裂,使得抗蝕性下降。由實驗結果得知,氧化鋯在沉積300秒燒結350℃時有較佳的抗蝕性。
浸泡實驗與金屬離子析出分析結果發現,經電解沉積氧化鋯的試片能降低50%以上的鉛離子釋出,且其它金屬離子釋出量都減少。另外刮痕試驗結果顯示,鍍膜在銅合金金屬之附著力大於基材的降伏強度。
