In the nitre bluing process, polished and cleaned steel parts are immersed in a bath of molten salts—typically potassium nitrate and sodium nitrate (sometimes with 9.4 grams (0.33 oz) of manganese dioxide per pound of total nitrate). The mixture is heated to 310 to 321 °C (590 to 610 °F) and the parts are suspended in this solution with wire.

A nitre bed is a similar process used to produce nitrate from excrement. Unlike the leaching-based process of the nitrary, however, one mixes the excrements with soil and waits for soil microbes to convert amino-nitrogen into nitrates by nitrification. The nitrates are extracted from soil with water and then purified into saltpeter by adding ...
Computer-aided process planning (CAPP) is the use of computer technology to aid in the process planning of a part or product, in manufacturing. CAPP is the link between CAD and CAM in that it provides for the planning of the process to be used in producing a designed part.
From the outset, correcting an iron deficiency may seem small, but it can make a world of a difference in helping you feel empowered and in control of your health. Restoring iron to your body can ...
Process manufacturing is a branch of manufacturing that is associated with formulas and manufacturing recipes, [1] and can be contrasted with discrete manufacturing, which is concerned with discrete units, bills of materials and the assembly of components. Process manufacturing is also referred to as a 'process industry' which is defined as an ...
The reunion carrying national-title stakes would be remarkable as a football story alone. Jack Sawyer, a star Buckeyes defensive end who will spend Friday trying to sack Ewers, was once his roommate.
