Basics of Grinding - Stanford University

about five percent of grinding. Hard ferrous materials are ground with "CBN", while non-ferrous materials and non-metals are best ground with diamond. The grain size of abrasive materials is important to the process. Large, coarse grains remove material faster, while smaller grains produce a finer finish. The binders that hold these abrasive grains together include: • vitrified bonds, a glass-like bond formed of

Superphosphate - an overview | ScienceDirect Topics

Phosphate fertilizers are prepared by beneficiation of phosphate rock to remove its impurities, followed by drying and grinding. The PO 4 in the rock may then be reacted with sulfuric acid to produce normal superphosphate fertilizer. Over 100 plants operating in the United States produce approximately a billion kilograms of phosphate fertilizer

Chrome plating: A guide for selecting the type of chrome plating

Hard chrome plating leaves a layer of chrome from 0.0008 to 0.0050 in. (from 0.020 to 0.127 mm) thick on the surface of the metal. In contrast, thin dense chrome plating has a thickness from 0.0002 to 0.0006 inch (0.005 to 0.015 mm). The thickness of chrome plating varies depending on the application. Chrome plating can be used over a wide temperature range from –70 °F to 800 °F (–57 °C to 427 °C) and can

Case-hardening - Wikipedia

Case-hardening or surface hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal (called the "case") at the surface. For iron or steel with low carbon content, which has poor to no hardenability of its own, the case-hardening process involves infusing additional carbon or nitrogen into the surface layer.
