Effect of a direct magnetic field on the interfacial microstructure between molten aluminium and solid iron

Many processing techniques, such as hot dip aluminizing, bimetal formation, liquid metal corrosion, cementing, welding and diffusion bonding, are basically dependent on interfacial reactions [1-3]. It is therefore important to investigate the formation and growth of intermetallic layers at the interface. There have been several studies carried out to examine chemical compositions and growth kinetics of intermetallic layers in the Al-Fe system [4-9]. Most authors have come to an agreement that…     

Advances in the research of nitrogen containing stainless steels

The current status of nitrogen containing stainless steels at home and aboard has been introduced. The function and existing forms of nitrogen in the stainless steels, influence of nitrogen on mechanical properties and anti-corrosion properties as well as the application of nitrogen containing cast stainless steels were discussed in this paper. It is clear that nitrogen will be a potential and important alloying element in stainless steels. And Argon Oxygen Decarbonization (AOD) refining can provide an advanced manufacture process for nitrogen containing stainless steels with ultra-low- carbon and high cleanliness.     

论Co表面薄膜Cu-BTA的缓蚀作用

某些金属材料的结构性能,对腐蚀损失极为敏感。如,作为磁盘及磁头的磁薄膜材料,在磁记录应用上有着非常重要作用的Co制品,就是如此。为此,人们往往采用缓蚀剂来处理Co制品。缓蚀剂的缓蚀作用,可以不同程度地减少或延缓Co制品的腐蚀损失。 但是,目前许多推荐使用的缓蚀剂,对Co制品的保护极为有限,一旦把Co制品脱离含
