Surface Structure Modification and Hardening of Al-SI Alloys explores the hardening of material surfaces using concentrated energy flows resulting in the nanostructuring of surface layers. The authors demonstrate how these methods achieve a reduction in plastic deformation of the surface and a more uniform distribution of elastic stresses near the surface during operational use, significantly reducing part failure. It presents results from research and scientific and technological enterprises involved with the modification of light alloy surfaces for use in the automobile and aerospace industries.
Additional key features include:
Addresses theoretical and experimental research computer simulations of structural phase transformations at the nanolevel to create new materials
Details and compares electroexplosion alloying, electron beam processing and electron-plasma alloying of an Al-Si Alloy
Explains multiphase plasma jet treatment to obtain high-quality coatings with good and high functional properties
