Leveraging Example for Gear Grinding

The use phase rather than the manufacturing phase of most consumer products dominates the environmental impacts [ASHB09]. The case study of an automotive manual transmission drivetrain exemplifies how higher manufacturing efforts can reduce the overall environmental impact [HELU11]. The automotive powertrain consists of the engine, transmission, and drivetrain (drive shaft, differentials and drive wheels). Gears […]

Analysis of Residual Stress via Polarisation Microscopy

Polarisation microscopy can detect stresses inside of transparent single-crystals, which is in particular important for monocrystalline diamond for jewelery [KLEB98, LENZ86]. Lattice defects in the crystals result in interference patterns and are recorded in double refraction pictures [MALZ00]. The results can be improved by embedding the grits into material with the same refractive index so […]

Vitrified Bonds

3.2.1 Chemistry and Types of Vitrified Bonds Vitrified bonds consist of silicates (red and white clay), kaolin (also known as white clay, Al2Si2O5(OH)4), field spar (KAlSi3O8-NaAlSi3O8-CaAl2Si2O8), quartz (also known as silicon oxide, SiO2), and frits, i. e. pre-molten bonding components [BEYE04, HADE66, PADB93, JACK11, p. 92]. The bond is sintered at temper­atures above 800 °C […]
