Vv. Uglov et al., Formation of complex Al-N-C layer in aluminium by successive carbon and nitrogen implantation, NUCL INST B, 147(1-4), 1999, pp. 332-336
The results of Auger electron spectroscopy and transmission electron micros
copy of the surface layer of aluminium after successive implantation by car
bon and nitrogen ions are presented in this work. The energy of implanted i
ons is 40 keV. The implantation dose varies in the range (3.3-6.5) x 10(17)
ions/cm(2). The findings show that successive implantation leads to the fo
rmation of two main layers in aluminium. The first layer is AlNCx (0 < x <
0.5) layer with violated hcp. AlN structure, where carbon atoms form bonds
with nitrogen atoms. The second layer contains disoriented Al4C3 precipitat
es and carbon atoms migrated from the first layer. The mechanism of migrati
on is discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
