| description | TIG torch welding technique is a conventional melting technique for the cladding of
metallic materials. Duplex stainless steels (DSS) show decrease in performance under
aggressive environment which may lead to unanticipated failure due to poor surface properties.
In this research, surface modification is done by using TIG torch method where silicon carbide
(SiC) particles are fused into DSS substrate in order to form a new intermetallic compound at
the surface. The effect of particle size, feed rate of SiC preplacement, energy input and
shielding gas flow rate on surface topography, microstructure, microstructure and hardness are
investigated. Deepest melt pool (1.237 mm) is produced via TIG torch with highest energy
input of 1080 J/mm. Observations of surface topography shows rippling marks which confirms
that re-solidification process has taken place. Melt microstructure consist of dendritic and
globular carbides precipitate as well as partially melted silicon carbides (SiC) particles. Micro
hardness recorded at value ranging from 316 HV0.5 to 1277 HV0.5 which shows increment
from base hardness of 260 HV0.5kgf. The analyzed result showed that incorporation of silicon
carbide particles via TIG Torch method increase the hardness of DSS. |
