A large number of transverse-cracks occurred in the weld metal of AISI 321 tube welded with HOCrl8Ni9Si2 welding wire and HJ260 welding flux after storing on the sea shore for several years. The cracks, fracture appearance and corrosion products have been studied by means of optical microscopes, SEM, EM and X-ray structural analysis. The cracks with obvious directionality and large depth-width ratio form initially at the surface of weld metal and appear to be highly branched. The fracture surface appears as...

A large number of transverse-cracks occurred in the weld metal of AISI 321 tube welded with HOCrl8Ni9Si2 welding wire and HJ260 welding flux after storing on the sea shore for several years. The cracks, fracture appearance and corrosion products have been studied by means of optical microscopes, SEM, EM and X-ray structural analysis. The cracks with obvious directionality and large depth-width ratio form initially at the surface of weld metal and appear to be highly branched. The fracture surface appears as quasi-cleavage steps, chevron, fan-shaped and river patterns, accompanied with characteristic secondary cracks, square corrosion pits and austenite skeleton dendrite. The corrosion products contain a large a-mount of Cl-, SO4= and O2. After detailed identification the failures have been proved as a result of stress corrosion cracking. The causes of its formation and the measures to avoid the failure have been proposed. It has been clearly suggested that stress corrosion cracking in this case relates to α phase dissolution. The relationship between the different fracture patterns and the initial columnar crystals, as well as the equiaxed grains has also been discussed.

采用AISI321钢、H0Cr18N9Si2焊丝,HJ260焊剂自动焊接的管件,于海滨存放数年后出现了大量焊缝横向裂纹。应用金相、扫描电镜、电子探针,X光与化学分析等方法对裂纹,裂纹断口及腐蚀产物进行了研究。该裂纹始于焊缝表面;有明显的宏观方向性;深宽比大;金相形态为有主干与分枝的树枝状。断口形貌呈类解理台阶、山形、扇形、河流等花样,还伴随有二次裂纹、方形蚀坑、奥氏体枝晶骨架等特征。腐蚀产物含有极高的Cl~-、SO_4~=、O_2。经多方论证、确定是SCC。分析了其产生的原因,提出了防止措施。明确提出了SCC与α相溶解有关。讨论了不同断口花样与原始柱状晶和等轴晶的关系。

In order to clarify the effect of Cr and Mo on the propagation of localized corrosion of steels, the electrochemical behavior of pure Cr and Mo and of some stainless steels was studied under conditions similar to those existing inside occluded corrosion cells (OCC) of steels.Oxygen-free FeCl_2 and/or CrCl_3 solutions were used for experiments.Cr is passive if pH is higher than ca.1.8.Therefore Cr may retard the propagation of localized corrosion of steels in its early stage.But the hydrolysis of Cr~(3+) may...

In order to clarify the effect of Cr and Mo on the propagation of localized corrosion of steels, the electrochemical behavior of pure Cr and Mo and of some stainless steels was studied under conditions similar to those existing inside occluded corrosion cells (OCC) of steels.Oxygen-free FeCl_2 and/or CrCl_3 solutions were used for experiments.Cr is passive if pH is higher than ca.1.8.Therefore Cr may retard the propagation of localized corrosion of steels in its early stage.But the hydrolysis of Cr~(3+) may change the pH to even lower values.At such low pH and high Cl~- co centration, Cr is active in the potential range of interest for localized corrosion of steels.Mo is passive in these more acidic conditions and the passivity of Mo in this potential range is attributed to the formation of a film of MoO_2, which is very stable and protective.Mo is thus effective to retard the propagation of localized corrosion of steels in its more advanced stage.

为阐明铬和钼对钢的局部腐蚀发展过程的影响,在类似于钢的闭塞腐蚀电池(OCC)内部溶液的条件下,研究了纯铬、纯铝和某些不锈钢的电化学行为。实验所用的溶液为无氧FeCl_2和/或CrCl_3。当pH高于约1.8时,Cr是钝化的,因此,在局部腐蚀发展的早期阶段,铬可起阻滞作用,但是,Cr~(3+)的水解可使pH降至更低值,在这种低pH和高Cl~-浓度条件下,在与钢的局部腐蚀对应的电位区,Cr是活化的。而在同样条件下,Mo是钝化的,而且在此电位区Mo的钝性归因于MoO_2膜的生成,这种氧化膜非常稳定,且保护性很好,因此,在局部腐蚀的深入发展阶段,Mo可有效地抑制腐蚀的发展。

The corrosion inhibtion properties and action forms of ZnBTA compound inhibitors for aluminum alloys in the neutral solution of high CL~- concentration were studied by determing the pitting corrosion potential, incubation period and anodic, cathodic polorization curves with elctrochemical methods. The results show that ZnBTA has the characteristics of combined anodic and cathodic inhibitors for it can remarkablly inhibit the initiation and growing of pitting corrosion and the anodic and cathodic process. The inhibition mechanism is also discussed.

采用电化学方法,通过测定孔蚀电位、诱导期和阴、阳极极化曲线,分析了复合缓蚀剂ZnBTA在中性高Cl~-水介质中对铝合金的缓蚀性能及缓蚀作用类型。实验表明:ZnBTA可显著阻滞孔蚀的诱发和发展;对电极阴、阳极过程均有明显抑制作用,具有混合抑制型缓蚀剂的特征。
