Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. [ 1 ] It is used to add mild corrosion resistance, for appearance, and to minimize light reflection. [ 2 ] To achieve maximal corrosion resistance the black oxide must be impregnated ...
Bluing, sometimes spelled as blueing, is a passivation process in which steel is partially protected against rust using a black oxide coating. It is named after the blue-black appearance of the resulting protective finish. Bluing involves an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the ...
An additional step can be added to the nitrocarburizing process called post-oxidation. When properly performed, post-oxidation creates a layer of black oxide (Fe 3 O 4), that greatly increases the corrosion resistance of the treated substrate while leaving an aesthetically attractive black color.

A deployment of Bloom Energy Servers outside eBay headquarters. The Bloom Energy Server or Bloom Box is a solid oxide fuel cell (SOFC) power generator made by Bloom Energy, of Sunnyvale, California, that takes a variety of input fuels, including liquid or gaseous hydrocarbons [1] produced from biological sources, to produce electricity at or near the site where it will be used.

Hinkley groundwater contamination. From 1952 to 1966, Pacific Gas and Electric Company (PG&E) dumped about 370 million gallons (1,400 million litres) of chromium -tainted wastewater into unlined wastewater spreading ponds around the town of Hinkley, California, located in the Mojave Desert about 120 miles north-northeast of Los Angeles. [1][2 ...
Phosphate conversion coating. Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates to improve corrosion resistance or lubrication or as a foundation for subsequent coatings or painting. [1][2][3] It is one of the most common types of conversion ...
Nitrox refers to any gas mixture composed (excepting trace gases) of nitrogen and oxygen that contains less than 78% nitrogen. [ 1 ][ 2 ] In the usual application, underwater diving, nitrox is normally distinguished from air and handled differently. [ 3 ] The most common use of nitrox mixtures containing oxygen in higher proportions than ...
