Abstract
This study includes enameling and study corrosion behavior of low carbon steel
(carbon continent =0.11%) in different types of corrosive media like the H2SO4, HCL
and NaOH both acidic solution (H2SO4, HCL) has PH= 2 with resistance acid solution
enameling and alkaline solution (NaOH) have PH= 12 with resistance alkaline
solution enameling. enameling process includes preparing and applying of frit by
ground coat method.
The corrosion rate calculated using weight loss method at temperature range (30, 40,
60, 90)oC for acidic and (30, 40, 50, 60) oC for alkaline solution. The results indicate
that corrosion rate increase with time and temperature for both H2SO4 and HCL
solution, while corrosion rate for NaOH solution decreases with time due to the
formation of unsolvable compounds on sample surface. These compounds may caused
insulation laminar reduced corrosion rate, while corrosion rate increases with
temperature because distortion of this layer.
