消除氫脆
【2】採用低氫擴散性和低氫溶解度的鍍塗層
一般認為,在電鍍Cr、Zn、Cd、Ni、Sn、Pb時,滲入鋼件的氫容易殘留下來,而Cu、Mo、Al、Ag、Au、W等T22合金鋼管鍍層具有低氫擴散性和低氫溶解度,滲氫較少。在滿足產品技術條件要求的情況下,可採用不會造成滲氫的塗層,如機械鍍鋅或無鉻鋅鋁塗層,不會發生氫脆,耐蝕性高,附著力好,且比電鍍環保。
【3】鍍前去應力和鍍後去氫以消除氫脆隱患若零件經淬火、焊接等工序後內部殘留應力較大,鍍前應進行回火處理,回火消除應力實際上可以減少零件內的陷阱數量,從而減輕發生氫脆的隱患。
【4】控制鍍層厚度,由於鍍層覆蓋在緊固件表面,鍍層在一定程度上會起到氫擴散屏障的作用,這將阻礙氫向緊固件外部的擴散。當鍍層厚度超過2.5μm時,氫從緊固件中擴散出去就非常困難了。因此硬度<32HRC的緊固件,鍍層厚度可以要求在12μm;硬度≥32HRC的高強度螺栓,鍍層厚度應控制在8μmmax。這就要求在產品設計時,必須考慮到高強度螺栓的氫脆風險,合理選擇鍍層種
除銹
第二:想要使除銹效果達到理想的效果,需要根據合金管表面的硬度,原始鏽蝕程度,要求的表面粗糙度,塗層類型等來選擇磨料,單層環氧,二層或者是三層聚乙烯塗層,要想達到理想的除銹效果,需要採用鋼砂和鋼丸的混合磨料。因為鋼丸有強化鋼表面的作用,鋼砂有刻蝕鋼表面的作用。
第三:想要獲得較好的均勻清潔度和粗糙度的分布,磨料的粒徑和配比的設計是相當重要的,因為粗糙度太大是很容易造成防腐層在錨紋尖峰處變薄的,同時會因為錨紋太深,就容易在防腐的過程中形成氣泡,嚴重影響著防腐層的性能。(在實際的操作中,磨料中的鋼砂和鋼丸的理想比例是很難達到的)
第四:在噴射處理之前,除去了合金管表面的油脂和積垢,還可以用加熱爐對管體預熱至40-60攝氏度,使合金管的表面保持乾燥的狀態,因為合金管表面是不含油脂等污垢的,這樣可以增強除銹的效果,另外,乾燥的合金管表面也是有利於鋼丸,鋼砂和銹和氧化皮的分離的,這樣就會使才除銹後的合金管表面更加的潔淨。
