Pemanfaatan Serbuk Gergaji Kayu sebagai Inhibitor Korosi Baja ASSAB 760 di Udara
Abstract: Corrosion problems
can cause serious harm, either directly or indirectly, such as the age of the
building construction to be reduced from the planned time, resulting in reduced
toughness, and environmental pollution. One way to slow the rate of corrosion is
to use the inhibitor extract sawdust. Extract sawdust containing lignin can
form complexes with iron from steel and adsorbed on the steel surface thus
blocking contact between the steel with oxygen in the air. This study aims to
utilize waste wood sawdust as steel corrosion inhibitors, view optical surfaces
steel before and after coated inhibitor and determine the efficiency of the
steel corrosion inhibition by extract sawdust. The method used to determine the
rate and efficiency of corrosion is the gravimetric method, which is based on a
reduction in weight (weight loss) of steel. Steel surface before and after the
coated sawdust extracts viewed using a stereo microscope with a magnification
of 40 times. The result showed that sawdust can be used as a corrosion
inhibitor of steel with optimum efficiency of 65,398%, from optical picture can
be seen that the steel surface is not coated sawdust extract rougher than the
surface of the coated steel.
