This test plan is according to the preprocessing, coloring and posttreatment . Test content mainly analyzes the impacts of pretreatment in each process on coloring effect.The results prove that : Pretreatment of alkaline cleaning time on determination is to the experiment formula, brass generally clean about ten seconds. If alkaline washinging time is short, Brass can39。堿洗。著色后用XRD，SEM等對其進行檢測，發(fā)現(xiàn)表面形貌比較均勻統(tǒng)一。配方二，配方三采用10%的硝酸分別酸洗5分鐘和3分鐘。此外，酸的濃度要合適，要能夠把銅上的氧化物除盡。堿洗時間短，除油不盡。研究結(jié)果表明：預處理中堿洗時間的判定很重要。預處理后進行著色及后處理。本次畢業(yè)設計的課題是銅表面拋光、著色技術研究。安徽工程大學機電學院畢業(yè)設計（論文）銅表面拋光、著色技術研究摘 要銅及其合金具有優(yōu)異的機械加工性能而廣泛地應用于各種工業(yè)。為了提高銅及銅合金的抗蝕性及裝飾性能, 進行表面著色處理是非常有效的處理方法。著色預處理過程主要包括銅表面打磨，機械拋光，堿洗工序和酸洗工序等方面。本次試驗的方案是按照預處理，著色及后處理的工藝流程來試驗的，試驗內(nèi)容是重點分析預處理各工序?qū)χЧ挠绊?。根?jù)本實驗的配方，黃銅一般清洗十秒鐘左右即可。時間過長,黃銅失光。本實驗配方一采用10%的硫酸溶液浸漬3分鐘。實驗證明這三種配方效果較好。關鍵詞：黃銅。酸洗。t pletely remove oil. Inversely, Brass can pletely remove oil. Moreover, the concentration of the acid is suitable to be able to put off the oxide film on the copper surface. Formula one use 10% sulfuric acid washing 3 minutes. Formula two and formula three prepares 10% nitric acid for dipping 5 minutes and 3 minutes respectively. Experimental results show that three kinds of formula effect is better. After staining, the XRD and SEM for inspecting found the surface morphology of brass is uniform.Key words: brass。acid washing 。3 000 年前(即青銅器時代)，我們的祖先已將青銅器用烈火燒烤，讓其表面氧化成綠褐色的保護層，使青銅器表面層晶體略有變化，達到長期保存而不生銹、又改變青銅器色澤的目的。其他色澤的生成與投入著色液中的鹽類有關，但基本原理相似。銅的化合物很多，其中黑色化合物有硫化亞銅、硫化銅、氧化銅及硫氧化銅；呈藍色的化合物有氫氧化銅、碳酸銅及堿式碳酸銅；呈紅色的化合物有亞鐵氰化銅、氧化亞銅等。建筑、裝潢及美術工藝品上著色，基本色澤有古銅色、古綠色、褐色、黑色等。硫化法和氧化法無需直流電源等設施，故比較方便，成本又低，很受用戶青睞。 47 第1章 緒論 各種
