Pengaruh Waktu Dan Sudut Penyemprotan Pada Proses Sand Blasting Terhadap Laju Korosi Hasil Pengecatan Baja AISI 430
Abstract: The purpose of this
study was to determine the influence of time and spraying angle on the process
of sand blasting on the rate of corrosion of AISI 430 painting. Research
conducted by the method of experimental research. Parameters in the sand blasting process used was the time of spraying with a
variation of 35 seconds, 55 seconds, 75 seconds and 95 seconds and spray angle
with the variation of 60°, 75° and 90°. This type of paint used paint is NC
(Nitro cellulose) with electrostatic spray method. Corrosion test carried out
by using a wet corrosion cell. Result showed that the angle and time of
spraying have an influence on the corrosion rate. The lowest corrosion rate
occurs at an angle of 90° spraying and spraying time of 35 seconds with the
corrosion rate (milli
inch / year)
1.72813E-06, whereas the
highest corrosion rate occurred
at an angle
of 60 °
and spraying time
95 seconds with
a corrosion rate
(mils/year) 0.00020454.
