Y. Andreev et al., ELECTROCHEMICAL CORROSION BEHAVIOR OF SHS-SYNTHESIZED DC MAGNETRON COMPOSITE TIC-BASED TARGETS AND SPUTTERED THIN-FILMS, Surface & coatings technology, 90(1-2), 1997, pp. 42-52
A number of dense composite materials, based on titanium carbide, were
synthesized using a coupled self propagating high temperature synthes
is (SHS)-consolidation technique. These composite materials have been
shown to posses both high hardness and good corrosion resistance. Thin
films wen produced from these dense composite materials by using them
as targets in d.c. magnetron sputtering. The corrosion resistance of
both the dense composite targets, and the resulting thin films in aque
ous HISO, and HCI solutions was studied for the following systems: TiC
0.48; TiC0.98: 80%TiC-20%TiB2; 70%TiC-20%Ti-10%Mo;60%TiC-10%TaC-20%Ti-
10%Mo; 60%TiC-12%Fe-8%Si-20%Mo; 72%TiC18%Cr3C2-10%Ni; 60%TiC-10%Mo2C-6
%TiN-16%Ni3Al-5%Mo-2%Cr. Increasing the TiB2 content in either the tar
get material or the thin film resulted in a decrease in the corrosion
resistance, while the corrosion resistance of the thin films was two t
o three orders of magnitude higher than that of the corresponding bulk
target material from which they were deposited. Thin films of 80%TiC-
20%TiB2, TiC0.98, 60%TiC-10%TaC-20%Ti-10%Mo, and 60%TiC-12%Fe-8%Si-20%
Mo were also compared under abrasive wear conditions in an aqueous med
ium containing SiC particles. The 80%TiC-20%TiB2 film exhibited the hi
ghest corrosion resistance.
