ABSTRACT
Purpose: Deposition of hard thin multilayer coatings is a common practice in improving the performance
of tools for many different applications. From this aspect Ti
3
SiC
2
, due to its lamellar structure and unique
combination of properties is a potential interlayer material candidate for thermo-mechanical application.
Design/methodology/approach: Multiphase Ti–Si–C thin films were deposited by the ion beam assisted
deposition (IBAD) technique from a single Ti
3
SiC
2
compound target on an AISI 316L steel substrate. To
optimize the deposition process, Monte Carlo simulations were performed; the range of the deposition
parameters was determined and then experimentally verified. Scanning and transmission electron microscopies
were used to examine the microstructure and quality of the deposited films. Mechanical properties were
determined by nanoindentation tests.
Findings: The deposited film was flat, smooth and dense with small crystalline particles. The hardness H
IT
of
coated substrates was in the range 2.7 to 5.3 GPa. The average calculated value reduced elastic modulus E
IT
for
coated substrates was 160 GPa. The hardness and reduced elastic modulus for uncoated substrates were H
IT
=
4.4 GPa and E
IT
= 250 GPa, respectively.
Practical implications: PVD techniques enable low substrate temperature deposition, preferred due to the
thermal limitations of the metallic substrates commonly used in industrial applications. The aim of this work
is low temperature deposition of Ti-Si-C film, from a single Ti
3
SiC
2
compound target, on 316L steel substrate,
using the IBAD technique, known for excellent film connection to the substrate.
Originality/value: Ion beam assisted deposition parameters were calculated and experimentally verified.
