A.Stainless steel fasteners are made of solid stainless steel, not coated with it. So if the type of stainless steel chosen is corrosion resistant to the environment it is placed in, it can last essentially forever. The better grades of stainless, like 316SS, can hold up indefinitely in mo...
stainless steel itself.” The ASTM spec goes on to describe passivation as “the chemical treatment of stainless steel with a mild oxidant, such as a nitric acid solution, for the purpose of enhancing the spontaneous formation of the protective passive film.” Passivation removes “free iron” c...
The higher system voltage (1.4 V) as well as the lower specific weight of zinc versus cadmium make the Ni–Zn system an attractive candidate for automotive battery systems. This is the reason why there have been so many efforts over a more than 70 year period with regard to this electroche...

Although the standard equili- brium potential of Al3+/Al (−1.66 V versus SHE) is much lower than that of Zn2+/Zn35, the formation of Al2O3 shell on the Al lamellas protects against the dissolution of Al and thus allows the selectively electrochemical stripping/plating of Zn in ...
Q. Compare service life (corrosion resistance) of same thickness coatings: electrodeposited zinc coating versus hot dip zinc coating? Assuming all other variables are constant, would there be a difference in service life (corrosion resistance) between a 7 micron thick electrodeposited zinc plating vers...
The existing problems of weld defects in welding zinc coated steels in a overlap situation are present in the automotive industry. The root cause is the different melting temperature of zinc and steel. Zinc vapourises already at 900C versus steel melts at 1500C. The result, if not taking care...

Full size image 2Experimental Section 2.1Preparation of ZnIn Electrode Commercial Zn foil (0.1 mm in thickness) and stainless steel mesh (100 mesh) were sonicated in acetone and ethanol, respectively, to clean the surface. The stainless steel mesh was covered with a Zn foil and passed through...
Dezincing leaching rates are improved by taking advantage of the higher exchange current density of the iron substrate versus the zinc coating. This is accomplished in practice by increasing the exposed interfacial zinc:iron surface area through shredding. Also, a leach control mechanism is proposed...
