Surface Alloying of Mg Alloys After Surface Nanocrystallization

Journal of Nanoscience and Nanotechnology, 2008
Surface 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 of hydroxyapatite coating

Acta Biomaterialia, 2008
Nanocharactered biomaterials, such as nanopowders, nanocrystalline compacts and nanostructured films, as well as materials with nanoscale roughness, have attracted much attention recently, due to their clear effects on cell response. Surface nanocrystallization of plasma-sprayed hydroxyapatite (HA) coating can be realized by conventional post-heat ...

Surface nanocrystallization of Ni3Al by surface mechanical attrition treatment

Materials Letters, 2006
Abstract 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
