Oct 17, 2017 · The causes of and remedies for defects in hard chromium deposits are explored in the first of this twopart PSF article from 1984. Photomicrographs and SEM (scanning electron microscope) photo­graphs will illustrate that most defects in various hard chromium deposits arise from defects in the basis metal. These defects may be in the original metal surface or may be caused by preplate finishing.

What Are the Effects of Sulfuric Acid on Metal?

+

Aluminum also forms a protective oxide layer; however, sulfuric acid and aluminum will react after some delay to produce hydrogen gas and aluminum sulfate. Another factor that can affect the combination is the solubility of the salt, or metal sulfate, formed by the reaction.

What is Passivation? How Does Stainless Passivation Work?

What is Passivation? How Does Stainless Passivation Work?

+

Stainless steel derives its corrosionresistant properties from the chromium content. Chromium, when exposed to oxygen (air), forms a thin film of chromium oxide that covers the stainless steel surface and protects the underlying iron from rusting. The purpose of passivation is to augment and optimize formation of the chromium oxide layer.
