| Summary: | Tungsten inert gas (TIG) surface modification with
Fe-based alloy can give protection against wear and corrosion
of metallic component material. In this study, an attempt has
been made to explore deposition of Fe-based alloy on
commercial purity titanium (CP-Ti) by TIG torch melting
process to improve resistance of substrate to wear and
corrosion. Three different powder blends with nominal
composition of 97Fe2C1Si, 94Fe 4C2Si and 91Fe6C3Si were
separately melted on CP-Ti using a conventional TIG welding
torch produced at 100 A and energy input 1350 J/mm.
Analysis of the results showed that TIG torch produced melt
pools geometry with good metallurgical bonding with the
substrate. The melt microstructures consisted of variety of
different TiC precipitates. Pores were conspicuously seen on
the melt microstructure modified with highest carbon content.
Both microhardness and wear resistance showed a significant
improvement particularly after TIG coating with 94Fe4C2Si.
Thus, it appears that an optimized composition of TIG coated
with 94Fe4C2Si was best to control abrasive resistance and
for the application of cylindrical liner. |
