【摘要】：用5083F鋁合金制造的船舶在海洋環(huán)境中以高速或高流速等狀態(tài)運(yùn)行時(shí)會(huì)受到少量腐蝕,適當(dāng)?shù)臒崽幚砜筛纳破淠透g性能。通過(guò)硬度、轉(zhuǎn)折電位、不同時(shí)效時(shí)間下的陰極極化電流密度及慢應(yīng)變速率試驗(yàn)找到了防止腐蝕的最佳熱處理?xiàng)l件,即在420℃下加熱樣品30 min,然后在水中冷卻;最佳時(shí)效條件是樣品在180℃下時(shí)效240 min。在海水中的慢應(yīng)變速率試驗(yàn)(SSRT)顯示,最佳條件下熱處理略降低了試樣的強(qiáng)度,但增加了伸長(zhǎng)率和斷裂時(shí)間,熱處理提高了其抗腐蝕性能。
[Abstract]:Ships made of 5083F aluminum alloy will be subjected to a small amount of corrosion when they are operating in the marine environment at high speed or high velocity of velocity. Proper heat treatment can improve their corrosion resistance by means of hardness, turning potential, The cathodic polarization current density and slow strain rate tests at different aging times have found the best heat treatment conditions to prevent corrosion. The sample is heated at 420 鈩，
