whole range of medical implants is justified by their superior mechanical properties (hardness, stiffness, etc.) compared, for example, to polymers. Other properties like biocompatibility or visibility in X-ray images also can be mentioned. One of their drawbacks is that electrochemical reactions take place on metallic surfaces in the human body. To replicate the real environment as closely as ...

The repair and rectification of corrosion damage continues to be a major factor in the life cycle costs of aircraft. The present approach to corrosion control is based on ‘Find-and-fix’. Once an area of corrosion is found, rectification is carried out as soon as possible. This often involves the blending away of corrosion damage and the re-protection of the blended area. Where the depth of corr...

Abstract In this work, the influence of tungsten on crevice corrosion resistance three super duplex stainless steels (SDSS) containing 0.0, 0.6, and 2.1 wt.% W was determined. The PD-GS-PD technique used to estimate critical repassivation temperature by performing tests at different temperatures. Additionally, long-term potentiostatic experiments were conducted as a function in natural seawater...
