15crmoG合金管是
無縫鋼管[1]的一種,其性能要比一般的無縫鋼管高很多,因?yàn)檫@種鋼管里面含Cr比較多,其耐高溫
[1]、腐蝕的性能是其他無縫鋼管比不上的,所以合金管在石油、化工、電力、鍋爐等行業(yè)的用途比較廣泛。
15crmoG合金管純化氫的原理是,在300—500℃下,把待純化的氫通入15crmo合金管的一側(cè)時(shí),氫被吸附在15crmo合金管壁上,由于鈀的4d電子層缺少兩個(gè)電子,它能與氫生成不穩(wěn)定的化學(xué)鍵(鈀與氫的這種反應(yīng)是可逆的),在鈀的作用下,氫被電離為質(zhì)子其半徑為1.5×1015m,而鈀的晶格常數(shù)為3.88×10-10m(20℃時(shí)),故可通過15crmo合金管,在鈀的作用下質(zhì)子又與電子結(jié)合并重新形成氫分子,從15crmo合金管的另一側(cè)逸出。在15crmog合金管表面,未被離解的氣體是不能透過的,故可利用15crmo合金管獲得高純氫。[2]雖然鈀對(duì)氫有獨(dú)特的透過性能,但純鈀的機(jī)械性能差,高溫時(shí)易氧化,再結(jié)晶溫度低,易使15crmo合金管變形和脆化,故不能用純鈀作透過膜。在鈀中添加適量的IB族和Ⅷ族元素,制成鈀合金,可改善鈀的機(jī)械性能11.汽車半軸套管用無縫鋼管(GB3088-82)是制造汽車半軸套管及驅(qū)動(dòng)橋橋殼軸管用的優(yōu)質(zhì)碳素結(jié)構(gòu)鋼和合金結(jié)構(gòu)鋼熱軋無縫鋼管鈀合金中,銀約占20—30%,其他成分(如金等)的含量<5%
