READ FULL REPORT |
Enclosed you
will find the report you requested on the relative resistance to corrosion of:
|
1.
new galvanized friction bolts from
Skema Industries.
|
2.
galvanized friction bolts the same as the first except that they were installed at
the NORCAT Underground Centre then pulled out
before corrosion testing.
|
3. plain steel bolts without a galvanized coating
|
The tests show the clear advantage of galvanized over plain steel and that the
damage done by installation has little effect on the corrosion performance of the bolts.
|
I would
suggest that a next step would be longer term corrosion followed by a tensile test which
would further substantiate the value of galvanized coatings on longevity. Your idea
of corrosion in simulated or actual sulphide mine water would be interesting as well.
