Micro-hardness measurement of photopolymer in stereolithography.

Journal of Photopolymer Science and Technology, 1997
The curing of liquid photopolymer is determined by the exposure (optical energy) deposited. In laser stereolithography, laser exposure is considered as non-homogenous within the radiation area. In order to investigate the difference of the cure degree within the cross section of a single cured strand, a micro-structure was evaluated by hardness ...

Is Young's Modulus a Critical Coating Property Determining Fouling‐Release Performance of Marine Coatings?

Advanced Engineering Materials, EarlyView.
The release of foulers from protective marine coatings is determined by several interrelated material properties, including the strength of Young's modulus, the flexibility of chain segments, the surface free energy, and the magnitude of hydrodynamic stress.

Micro hardness measurements on lead silicate glass

Bulletin of Materials Science, 1998
The synthesis of lead silicate glass suitable for fabrication of compression type glass to metal seals has been studied with varying amounts of modifier ions (Na, K and Ba). A three-stage heating schedule was evolved for the preparation of glass. While, some of the constituents were taken in the form of oxides, the others were either in the form of ...

Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects

Advanced Engineering Materials, EarlyView.
Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...
