Electron Beam Surface Engineering of Spray-Formed Aluminium-Silicon Alloys
Aluminium alloys are commonly used lightweight construction materials. Spray-formed alloys, in particular, represent a group of materials with very high Si contents and a homogeneous distribution of primary Si and other alloying elements in solid solution and intermetallic compounds. The paper deals with current results of EB surface alloying and dispersing of such alloys using a high frequency beam deflection technique. The results concerning the interactions between the EB and the material and its effects on the layer microstructure, characteristic layer properties as well as detailed researches into friction and wear behaviour and future prospects for the technological transferability to industrial applications will be discussed.
