Effect of Heat Treatment on Tribological Properties of Ni-B Coatings on Low Carbon Steel: Wear Maps and Wear Mechanisms

Among the alternatives for using low-carbon steel in parts with heavy wear, as gears and bearing surfaces, Ni-B electroless coatings deposited on these steels are considered due to their wear resistance. Wear maps, elaborated from friction or wear results found for different evaluated conditions, are a very useful tool for the selection of materials based …

IYPT 2019 Elements 032: Germanium: Camera lenses and guitar effects pedals

Element 32 in our International Year of the Periodic Table series is germanium. Found in some camera lenses and guitar effects pedals, it’s also present in some LCD TVs. Germanium oxide has a high index of refraction, meaning light travels through it particularly fast. This gives it applications in wide angle lenses for cameras and microscope …
