Abstract:
The purposes of this experiment are to study the effects of corrosion behavior of an as-cast
ER5356 filler metal and to define the weight gain in kinetic oxidation analysis. The specimen
was subjected to high temperature oxidation in a box furnace in flowing air gas. The oxidation
test was performed between temperatures of 300°C until 600°C. From this investigation,
oxidation weight change measurement showed that the breakaway oxidation was occurred at
500°C after 40 hours exposure. It shows that at 500°C, the welded alloy failed to form the
protective oxide layer and suffered rapid breakaway oxidation. The decreasing of weld quality
was observed due to the scale formation of oxide metal that will be discussed in terms of
morphology and growth analysis.
