Surface Nanocrystallization for Bacterial Control
Langmuir, 2010Stainless steel is commonly used in indwelling medical devices, food preparation, and heavy industry. Bacteria display reduced adherence to nanocrystallized stainless steel. In this article, we present quantitative information on the surface adhesive force, surface electron work function, and bacterial adherence to surfaces of nanocrystallized ...

Surface Self-nanocrystallization in Copper Electroforming
Journal of Materials Engineering and Performance, 2018The coarse columnar grain layer generated on top of electroforming deposits leads to low surface strength and poor global performance of deposits. Here, we introduce a particle abrasive-induced surface self-nanocrystallization process, which is a part of the electroforming process rather than involving complex poststeps using special equipment.

Surface Alloying of Mg Alloys After Surface Nanocrystallization
Journal of Nanoscience and Nanotechnology, 2008Surface nanocrystallization using a surface mechanical attrition treatment effectively activates the surface of magnesium alloys due to the increase in grain boundary diffusion channels. As a result, the temperature of subsequent surface alloying treatment of pure Mg and AZ91 alloy can be reduced from 430 °C to 380 °C.

Surface Nanocrystallization by Surface Mechanical Attrition Treatment
Materials Science Forum, 2008Based on strain-induced grain refinement, a novel surface mechanical attrition treatment (SMAT) technique has been developed to synthesize a nanostructured surface layer on metallic materials in order to upgrade their overall properties and performance without changing their chemical compositions.

Surface nanocrystallization modification of anhydrite
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2012Abstract This paper reported a successful preparation of CaCO3/anhydrite composites of anhydrite coated with nanosized CaCO3 by chemical precipitation route using the Ca(OH)2–H2O–CO2 reaction system. The samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and BET ...

Surface nanocrystallization of Ni3Al by surface mechanical attrition treatment
Materials Science and Engineering: A, 2006Abstract The mechanical property and microstructure evolutions of Ni3Al intermetallic compound subjected to surface mechanical attrition treatment (SMAT) were investigated in relation to surface nanocrystalization. Grain size in topmost surface of SMATed Ni3Al alloy was refined to a minimum size of about 10 nm, and then increased with the enhancement
