【摘要】：鐵鎳合金具有優(yōu)異的軟磁特性和力學(xué)特性,因此在低頻磁場(chǎng)屏蔽領(lǐng)域得到了廣泛的應(yīng)用,并且隨著設(shè)備輕量化、微型化的發(fā)展和需要,磁場(chǎng)屏蔽材料也朝著輕、薄的薄膜材料發(fā)展。鐵鎳合金磁屏蔽薄膜的制備方法主要有磁控濺射法和電沉積法,其中電沉積制備鐵鎳合金薄膜是一種便宜且實(shí)用的方法。本論文研究目標(biāo)是采用電沉積技術(shù)制備可剝離的鐵鎳合金薄膜,取得了以下研究成果:(1)采用電化學(xué)方法對(duì)鐵鎳合金電沉積過(guò)程進(jìn)行了研究,得到了不同工藝參數(shù)對(duì)鐵鎳合金電沉積過(guò)程極化行為的影響,為工藝參數(shù)的設(shè)計(jì)提供了理論依據(jù)和研究方向。(2)系統(tǒng)研究了鍍液中鐵鎳離子濃度比、pH、溫度、電流密度等工藝條件對(duì)鍍層中鐵含量的影響,并對(duì)鍍層的物相結(jié)構(gòu)、表面形貌、內(nèi)應(yīng)力、磁性能及屏蔽效能等進(jìn)行了表征,優(yōu)化出了最優(yōu)工藝參數(shù),可以得到性能優(yōu)異、可剝離的鐵鎳合金薄膜。(3)研究了不同的陽(yáng)極體系對(duì)鍍液、鍍層中成分變化的影響,從而得到了最適合的陽(yáng)極體系,保持了鍍液中被鍍金屬離子濃度的動(dòng)態(tài)平衡;對(duì)影響電鍍液穩(wěn)定性的其他因素,如鍍液pH值的變化、添加劑的消耗等進(jìn)行了研究。提出了維持鐵鎳合金電鍍液穩(wěn)定性的方案,為進(jìn)行連續(xù)電沉積鐵鎳合金薄膜提供了實(shí)驗(yàn)依據(jù)。(4)根據(jù)制備小片鐵鎳合金薄膜的方法及規(guī)律設(shè)計(jì)了一種電沉積制備鐵鎳合金連續(xù)薄膜的裝置,制備出了連續(xù)的鐵鎳合金薄膜。
[Abstract]:Due to its excellent soft magnetic properties and mechanical properties, Fe-Ni alloys have been widely used in the field of low frequency magnetic field shielding, and with the development and need of lightweight and miniaturized equipment, magnetic shielding materials are becoming lighter. Thin film materials developed. The preparation methods of Fe-Ni alloy magnetic shielding films mainly include magnetron sputtering and electrodeposition. Electrodeposition is a cheap and practical method for the preparation of Fe-Ni alloy films. The purpose of this thesis is to prepare the iron-nickel alloy thin films by electrodeposition. The following research results are obtained: (1) Electrochemical method is used to study the electrodeposition process of Fe-Ni alloy. The effects of different process parameters on the polarization behavior of Fe-Ni alloy electrodeposition were obtained, which provided the theoretical basis and research direction for the design of the process parameters. The effect of current density and other technological conditions on the iron content in the coating was studied. The phase structure, surface morphology, internal stress, magnetic properties and shielding efficiency of the coating were characterized. The optimum technological parameters were optimized and the excellent properties were obtained. The effect of different anodic systems on the composition change of plating solution and coating was studied. The most suitable anodic system was obtained and the dynamic balance of the concentration of metal ions in the plating bath was maintained. Other factors affecting the stability of electroplating bath, such as the change of pH value, the consumption of additives and so on, were studied. The scheme of maintaining the stability of Fe-Ni alloy electroplating solution is put forward. This paper provides experimental basis for continuous electrodeposition of iron-nickel alloy thin films. According to the methods and rules of preparing small iron-nickel alloy films, a device for electrodeposition of Fe-Ni alloy continuous films is designed, and continuous Fe-Ni alloy films are prepared.
