CreviceCorrosion
Results from the pitting and crevice corrosion testing revealed
that the silicon coated 316L stainless steel experienced no
crevice corrosion and only slight pitting (figure 1a)
The bare 316L stainless steel coupons experienced severe
crevice corrosion and pitting corrosion (figure 1b)
Table 1 summarizesweight loss resulting from exposure to the
6%w/w ferric chloride solution required by thismethod.
Elimination of crevice corrosion is an important step in reducing
equipment depreciation in corrosive environments.
