Abstract
Abstract The present study investigates comparison
between corrosion behavior of 2507 and 2205 DSS in
artificial saliva for orthodontic wires. The heat treatment is
necessary for 2507 and 2205 duplex stainless steel to
remove or dissolve intermetallic phases, removed segregation and to relieve any residual thermal stress in DSS which
may be formed during production processes. The corrosion
behavior of a 2507 and 2205 DSS in artificial saliva was
studied by SEM, HV test and potentiodynamic measurements. The results indicate that the corrosion resistance
mainly depends on presence of secondary phases (sigma
phase) and ferrite /austenite ratio, it’s revealed that the
corrosion resistance of 2507 DSS higher than 2205 DSS in
artificial saliva at 37 °C.
