從21世紀鋼鐵工業的現狀來看，科技含量和產品附加價值低的普通鋼鐵品種產能過剩，已達到市場飽和，而使用高科技研發新的鋼鐵合金不銹鋼也無法滿足現今各科研產業的現況，而且市場仍在不斷拓展。此外，鋼鐵材料給人傳統成熟的印象，然而其在性能提升上仍有極大的發展空間，為達到高品質的提升及附加價值，諸多高級鋼品的開發及其生產製程亦不斷精進，如融合合金工程鋼品。但是融合合金工程鋼品的價格高昂且精煉過程耗費較高的能源，無法達到簡化製程，減少成本，行較環保之效益。因此，從科技研發發展的角度看，探索出新的方法，改善鋼鐵表面結構性能，鋼鐵材料之表面抗蝕與耐磨耗性能若能同時有效提升，則能廣泛應用在汽車、家電、機密機械、光電、半導體及生醫器材等高價值之終端產品及其相關零附件上，將可取代製程繁瑣成本高昂之各種合金鋼鐵。優化製備方法是該方面研究的首要任務，而電漿方面增強電化學表面陶瓷技術，即微弧氧化技術，為該方面的研究提供了一個全新的研究階段。本研究試圖為微弧氧化技術開闢新的領域，也為鋼材的表面處理探索一條新途徑將提供一個全新的研究階層。
本研究針對不銹鋼表面利用單極與雙極脈衝電源模式微弧氧化技術在鋁酸鹽電解質中製備具有高硬度耐磨耗及耐蝕性之陶瓷氧化膜，由研究結果顯示：微弧氧化生成之不銹鋼表面陶瓷氧化膜主要由氧化鋁(Al2O3)和剛玉(α-Al2O3)及鐵鋁尖晶石(FeAl2O4)組成；由單極脈衝電源模式(頻率150Hz、佔空比40%)結果發現，所製備的陶瓷氧化膜表面最佳結果:硬度為(1783Hv)；膜層厚度21.60μm；平均粗糙度為Ra＝12.055；摩擦係數及磨耗損失量0.4149及0.0065mg/100m ；耐蝕性較基材約高1500倍，而以相同實驗參數雙極脈衝電源模式陶瓷氧化膜表面最佳結果為：結果發現，陶瓷氧化膜最佳硬度為(1532 Hv)，膜層厚度達53.97μm；平均粗糙度Ra＝14.135；摩擦係數及磨耗損失量分別為0.5643及0.0245 mg/100m；耐蝕性較基材約高300倍。

The current status of the steel industry in the 21st century shows the overcapacity of ordinary steel varieties with low technological content and product added value has reached market saturation but new stainless alloy steel market is still expanding. However, the use of high-tech and development of new stainless alloy steel cannot meet the current demand of various industries. In addition, steel materials give people the impression of traditional maturity but actually, there is still a lot of room for improvement in performance. In order to achieve high-quality enhancement and added value, the development of many high-end steel products and their production processes are constantly improving, such as fusion alloy engineering steel products. However, the price of fusion alloy engineering steel products is high and its refining process consumes high energy, which cannot achieve simplified manufacturing processes, reduced costs, and more environmentally friendly benefits. Therefore, from the perspective of scientific research and development, new methods have been explored to improve the structural properties of steel surfaces. If the surface corrosion resistance and wear resistance of steel materials can be effectively improved at the same time, they can be widely used in automobiles, home appliances, precision machinery, optoelectronics, semiconductor, biomedical equipment and other high-value end products and related parts and accessories, and will be able to replace all kinds of tedious and costly alloy steel. Optimizing the preparation method is the primary task of the research in this area and the enhancement of electrochemical surface ceramic technology in the plasma aspect, that is the micro-arc oxidation technology, provides a new research stage in this area. This research attempts to open up a new field for micro-arc oxidation technology and to explore a new way for the surface treatment of steel, and will provide a brand-new research level.
The research aims at using unipolar and bipolar pulse power mode of micro-arc oxidation technology on the surface of stainless steel to prepare a ceramic oxide film with high hardness, wear resistance and corrosion resistance in aluminate electrolyte. The research results show that stainless steel produced by micro-arc oxidation to form the ceramic oxide film on the surface is mainly composed of aluminum oxide (Al2O3), corundum (α-Al2O3) and iron-aluminum spinel (FeAl2O4). It is found that by the unipolar pulse power mode (frequency 150Hz, duty cycle 40%), the best result on the surface of the ceramic oxide film is hardness 1783Hv, film thickness 21.60μm, average roughness Ra=12.055; friction coefficient and abrasion loss are 0.4149 and 0.0065 mg/100m; corrosion resistance is about 1500 higher than that of the base material. The best result of the ceramic oxide film surface by the bipolar pulse power mode with the same experimental parameters shows the hardness of the ceramic oxide film is 1532 Hv; the film thickness is 53.97μm; the average roughness is Ra=14.135; the friction coefficient and abrasion loss are 0.5643 and 0.0245 mg/100m respectively; the corrosion resistance is about 300 times higher than that of the base material.
