This CuNiFer alloy pipe is used in a seawater cooling system and is electrical insulted with nearby metals; this prevents galvanic corrosion to occur since there is no contact with other metals. I've seen multiple sources that say CuNiFer is very corrosion resistance. The pipe is still... Ter...
The temperature and time of austenitization are of great practical importance during the austempering heat treatment of ductile iron, as these factors influence the transformations in the solid state, modifying the matrix microstructure and the resulting mechanical properties of the material obtained after...
This illustrates the importance of low adhesion and high levels of buffer air in the corrosion resistance of metals. In addition to the above-mentioned superhydrophobic surface, the SLIPS surface can also bring good corrosion protection to Mg alloys. Wei et al. [49] fabricated a surface capable...

, it is important that metals possess high resistance against corrosion III) Introduction to Corrosion Corrosion can be defined as an environmental process which attacks metal byy converting it into its stable oxide,sulphide or hydroxide form.It gradually destroys the mechanical properties of metals. ...

The value of B should be determined empirically. However, for most cases, it can be assumed to be 0.026 V for active and 0.052 V for passive corrosion of steel in concrete (Andrade and González, 1978; Andrade et al., 1990). The resistance measured by the LPR is actually the sum of ...
To assess the performance of the added GA inhibitor at different concentrations on the chloride-induced corrosion resistance of rebars embedded in mortars, EIS experiments were conducted for the control, the 0.25% methanol, and the formulated inhibitor at different concentrations (0.0625%, 0.125%, and...
