At our institute, micro grinding experiments with electroless plated MPGTs (diameter 50 μm) in 16MnCr5 steel workpieces were conducted using the MQL method with a MWF made out of distilled water and 0.02 wt.% of sodium dodecyl sulfate (SDS). This MWF was compared with dry machining and experiments with distilled water as a coolant.Web

Oxygen is the most abundant element on the earth's crust. The earth's surface is composed of the crust, atmosphere, and hydrosphere. About 50% of the mass of the earth's crust consists of oxygen (combined with other elements, principally silicon). Oxygen occurs as O 2 molecules and, to a limited extent, as O 3 (ozone) molecules in air.Web

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].Web
