中文摘要 | 利用電流脈波可以對SUS304不鏽鋼在2.5MCrO��+5MH�特O�健輔G及75 ℃溫度中進行發色處理,電流脈波中的正、負電荷密度比值是其有決定性的重要 參數,其值在1:1時可以製得彩色皮膜,在1:3時則無法製得。正電流部份相對於 甘汞參考電極電位大約為+1090mV,相當於SUS304不鏽鋼在這種環境下的過鈍態 電位,而負電流部份的電位則隨皮膜的厚度/顏色之改變而改變,當此部份的電 位達到一特定值即可製得特定顏色之彩色皮膜。電流脈波法相對於INCO法有分 散陽極的成核位置或減低陽極解離作用,所製得之彩色試片之表面晶界受到的腐 蝕較淺。adhesion及abrasive的microcutting皮膜磨耗型態出現在fretting試驗中,而 tensile cracking的刮痕型態則出現於皮膜的scratch試驗中。鐵成份的濃度在皮膜中 遠低於在底材,且在皮膜中含有高濃度的氧量,鎳銘濃度則稍高或相同。 |
英文摘要 | A rectangular wave form pulse current was applied to color SUS304 stainless steel in 2.5 MCrO�� +5 MH�特O�� at 75℃. The current charge density was a dominant factor in the coloring process. When the current charge density ratio of positive to negative in a single cycle pulse was 1: 1, it was successful to color the stainless steel, but it failed in coloring as the ratio was 1:3. The potential on the specimen surface in the positive pulse current kept in a steady value of + 1090 mV vs. SCE in coloring process. A great variation of the potential in the negative current region was observed. The pulse current coloring method dispersed the anodic nucleation site and/or decreased the anodic dissolution in the grain boundary. Adhesion and micro cutting of abrasive failure mode were observed in the colored film by fretting test, and tensile cracking failure mode was observed in the colored film by scratch test. The content of iron in the colored film was lower than that in the substrate. High oxygen content was detected in the colored film. The concentration of Ni and Cr in the colored film were slightly higher than that in the substrate. |
