€: Ji VotavaZinc coatings on steel protect against corrosion in two ways: By a barrier effect, i.e. they prevent oxygen and moisture from reaching the steel surface. By giving cathodic protection at scratches, chips, edges etc. Zinc is a metal with a relatively low galvanic potential and a high tendency to corrode.
2008-7-7€f the aluminum mounting plate has threaded holes, the plate too should be chromate conversion coated. If the plate has through-holes, and zinc plated nuts are used on the rod, the plate could be anodized, which would afford greater corrosion protection and less galvanic corrosion issues. Good luck.

The question of corrosion resistance comes up often. In zinc plating, protection to white corrosion products is the function of the chromate. Protection to red rust is the function of the chromate plus the thickness of the zinc plate. ASTM B201-80 [affil. link to spec at Techstreet] addresses corrosion resistance to white corrosion products.

Aluminum Corrosion. Some of the present aluminium corrosion challenges are the ramifications from the elimination of chromates as inhibitors in protection schemes, the tolerance of higher impurity levels due to the increased use of recycled metal, the integration of lithium into alloys while retaining corrosion resistance and the sensitisation of non-heat treatable aluminium-alloys.
