??-4D??(\L???>q5???Y??/???????u*?K???x???? ???????L+8?又被稱為不銹鋼35%-銅腐蝕試驗(yàn)方法，適用于船用不銹鋼焊接接頭在加由銅屑的銅—溶液中的晶間腐蝕試驗(yàn)。
GB/T 3949-2001
GB/T 3949-2001 船用不銹鋼焊接接頭晶間腐蝕試驗(yàn)步驟：
1、 將 100 g 銅溶解于 700 mL 蒸餾水中，再加入 100 mL ，用蒸餾水稀釋至 1000 mL,配制成試驗(yàn)溶液。銅應(yīng)符合 GB /T 665 中分析純的要求，應(yīng)符合 GB/T 625 中分析純的要求。
2、 在燒瓶底部鋪一層銅屑，銅屑應(yīng)符合GB/T 467的要求。放置試樣時(shí)，在保證每個(gè)試樣與銅屑接觸的情況下，同一燒瓶中允許放同一母材及同一焊接材料的試樣，試樣之間應(yīng)互不接觸。
3、 試驗(yàn)溶液量與試樣總表面積之比至少為 8 mL/cm`，每次試驗(yàn)均應(yīng)采用新配制的溶液。銅屑可用溫水洗滌后重復(fù)使用。
4、 將燒瓶放在加熱裝置上加熱，并通以冷卻水。待加熱至溶液微沸騰開始計(jì)時(shí)，沸騰時(shí)間應(yīng)保持20士5h，對(duì)試驗(yàn)結(jié)果有爭(zhēng)時(shí)，沸騰時(shí)間取 20 h。在規(guī)定的時(shí)間內(nèi)，試樣必須完全浸沒在試驗(yàn)溶液中。
5、 試驗(yàn)結(jié)束后，取出試樣洗凈、干燥，并進(jìn)行評(píng)定
