Neodymium Iron Boron is an alloy made mainly from a combination of Neodymium, Iron, Boron, Cobalt and varying levels of Dysprosium and Praseodymium The exact chemical composition within NdFeB depends on the grade of NdFeB. Dysprosium and Praseodymium are added as a replacement for some of the Neo...
Very often it is necessary to redress the corner of a grinding wheel to maintain a sharp, 90 degree corner. Instead of disrupting the grinding operation and mounting a wheel dresser, it is possible to simply use the boron carbide stick manually. With some practice this becomes routine and is...

These coatings can be made of simple metals as well as binary and ternary alloys, which improve corrosion, oxidation, and wear resistance. An electrochemical deposition is a low-cost option for thin-film synthesis since it does not require complicated or expensive equipment and employs common raw...
It is proved that atoms are semi-classical electronic systems in the sense of closeness of their exact quantum spectrum of electronic energies with the spectrum calculated in the semi-classical approximation. On this basis, a semi-classical model of the atom is introduced, within which the potenti...
