Nitriding Process and Nitriding Steels The purpose of nitriding is to enrich the surface layer of a work piece with nitrogen in order to increase the hardness in the surface. The process of nitriding takes advantage of the low solubility of nitrogen in the ferritic crystal structure to promote the precipitation of iron nitrides or alloy nitrides.

What is Etching? Top 10 amazing movie makeup transformations. Etching is a printmaking process that dates back 500 years. It involves sheets of metal, usually made of copper or zinc, and acid used to etch the print onto the metal. The artist can use complicated methods to create different effects, but always relies on acid to create an image on the plate.

Nital Nital is a name and is a solution of alcohol and nitric acid commonly used for routine etching of metals. It is especially suitable for revealing the microstructure of carbon steels. The alcohol can be methanol, ethanol or methylated spirits. Mixtures of ethanol and nitric acid are potentially explosive.

Ninhydrin, and Iodine-Fuming Ninhydrin, and Iodine-Fuming. Ninhydin is a chemical that reacts with the aminio acids found in fingerprints. When the chemical contacts the amino acids, the combination of the two turns a bright purple color. The coloring is known as Ruhemann’s purple, named after the man who discovered ninhydrin, Siegfried Ruhemann.inhydrin comes in pre-mixed aerosol cans and, in a chrystal form. When using the chrystals, detectives and crime scene investigators must mix the ninhydrin with a carrier, such as acetone – the same chemical that’s found in fingernail polish remover – or alcohol. The mix is then placed in a spray bottle for use.

- Nitrification, or the oxidation of ammonia via nitrite to nitrate by chemolithotrophic bacteria, is a key process in the global nitrogen cycle. Two types of anaerobic chemolithotrophs oxidize hydrogen with carbon dioxide as electron acceptor: methanogens and homoacetogens, producing methane and acetate, respectively.

Dye penetrant inspection Dye penetrant inspection, also called liquid penetrate inspection or penetrant testing, is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials. The penetrant may be applied to all non-ferrous materials and ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability. LPI is used to detect casting, forging and welding surface defects such as hairline cra
