Improved Surface Wettability of Water by Applying SiC/Ti6Al4V Coatings on Carbon/Carbon Composites

Advances in Materials Science and Engineering, 2013
SiC/Ti6Al4V coatings were applied on carbon/carbon composites to improve the surface wettability of water. SiC interlayers were preprepared by pack cementation to bond both the carbon/carbon composites and the Ti6Al4V, and then the Ti6Al4V coatings were ...

Effect of strontium and cooling rate upon eutectic temperatures of A319 aluminum alloy [PDF]

, 2004
DTA analysis was used to investigate the solidification reactions of alloy A319 with either 12 or 136 ppm of Sr added. Strontium does not affect primary solidification of (Al) dendrites but modifies the kinetics of the (Al)–Si eutectic. The effects of Sr

Five-dimensional imaging of freezing emulsions with solute effects

, 2018
The interaction of objects with a moving solidification front is a common feature of many industrial and natural processes such as metal processing, the growth of single-crystals, the cryopreservation of cells, or the formation of sea ice. Solidification

Surface remelting strategy for enhancing forming quality in laser directed energy deposition of Al2O3/GdAlO3/ZrO2 eutectic ceramics: Defect suppression and microstructure evolution

Journal of Advanced Ceramics
The intrinsic brittleness of ceramic materials and the complex temperature field used during laser directed energy deposition (LDED) inevitably lead to the formation of surface and internal defects in the fabricated components, which significantly affect
