傳統防鏽油係含接觸式的防鏽劑，其必須完全覆蓋於金屬表面，形成油性阻隔層，方可防止腐蝕物質的侵蝕。然而，金屬表面由許多小的凸峰與凹谷所形成，當防鏽油漸漸乾化後，外露的凸峰金屬表面將與空氣或腐蝕物質接觸，而產生點狀的鏽斑。
防鏽油中所含的正、負電離子將緊密地吸附於金屬表面上，形成溼式單分子阻隔層，以防止水份、氧與硫化氫等污染物的侵蝕。利用防鏽油漸漸烘乾形成乾鍍膜，就是所謂的”乾式單分子阻隔層”。乾式單分子阻隔層保護外露的凸峰金屬表面，以防止空氣與腐蝕物質的侵蝕，使金屬不易產生鏽斑。用此特點，將鉚釘加熱到設定的溫度投入防鏽油中，使鉚釘表面因高溫與油接觸而產生一層油膜(乾式單分子阻隔層)，多餘油份以脫水機脫乾，剩餘表面殘油漬用烤箱將防鏽油中揮發性有機物烤乾，有效提升防鏽效果，並能解決表面太多殘油漬問題。
本研究以兩種黏度與油膜厚度不同的防鏽油，用不同溫度烘烤（50度、80度、100度、120度、150度）烘烤後浸漬防鏽油，再以100度烘烤乾後，以鹽霧測試結果作比較。
由研究結果顯示出鍍鎳鉚釘防鏽油處理程序，加熱鍍鎳鉚釘50度以上，可以改善原鍍鎳鉚釘的鹽霧測試防鏽效果2-3倍，有效解決鍍鎳鉚釘防鏽時間太短問題。
電鍍鎳加665防鏽油烘烤溫度150度通過鹽霧測試時間為48小時、殘油量在容許範圍內，為本次研究報告的最佳化組合。

The traditional anti-rust oil system contains contact-type rust inhibitor, which must be completely covered on the metal surface, forming an oily barrier layer to prevent the erosion of corrosive substances. However, the metal surface is formed by many small bumps and valleys and when the rust-proof oil gradually dries, the exposed bump metal surface will contact with air or corrosive substances, resulted in spot-shaped rust spots.
The positive and negative ions contained in the anti-rust oil will be tightly attached to the metal surface, forming a wet single-molecule barrier layer to prevent the erosion of water, oxygen and hydrogen sulfide and other pollutants. The use of rust-proof oil gradually dried to form a dry coating is called "dry single-molecule barrier layer." Dry single-molecule barrier layer protects exposed convex metal surfaces to prevent the erosion of air and corrosive substances, making the metal less prone to rust spots.
With this feature, the rivets are heated to the set temperature in rust-proof oil so the rivet surface produces a layer of oil film (dry single-molecule barrier layer) because of high temperature and oil contact. Excess oil is dried by the dehydrator and the organic components of the surface residual oil stains will be volatilized by the oven. Not only does the process effectively improve the rust-proof effect, but also solve the problem of too many residual oil stains on surface.
By use of two kinds of anti-rust oil owning different viscosity and film thickness, nickel-plated rivets were baked at various temperatures (50C, 80C, 100C, 120C, and 150C) and then dipped into the rust-proof oil. After immersion, the rivets were baked at 100 C and then tested by salt spray for comparison.
Experiments show that the improvement of oil rust-proof for nickel-plated rivets. Nickel-plated rivets endured salt spray test from less than 2 hours to more than 48 hours. This indicates that it may be effectively solved for the problem of nickel-plated rivets rust prevention time being too short.
The results of this study show that the baking temperature 150C of nickel plated plus 665 rust-proof oil passed 48 hours salt spray test and the residual oil was within the allowable range, which is the best combination of this experiment.
