Recommended Salt Corrosion Protection
(OP)
I deal with equipment that is used in the commercial transit field (buses and trains). Many of our components are mild steel with a powder coat finish. These usually have to pass a 100 hour or sometimes even 1000 hour salt-spray test, which isn't the problem. The problems come from the field after our equipment has been installed, and the painted finish is compromised by road debris.
Chips expose the metal, and road salts take their toll. We have looked into zinc plating, but these aren't durable. I was hoping that by posting in this forum, I might be lead to some other finishes that may hold up under the conditions I have detailed. Service lift of our products is on the order of 5-7 years, but may be as long as 10-15 years.
Thanks

1. zinc phosphate metallic base coat
2. chemical bonding adhesion
3. PTFE heat cured fluoropolymer blue top coat
It has been tested to 4000 hr salt spray, and doesn't easily come off due to abrasion.

I'm talking of protecting casing at depths of 500 ft or more. Cathodic protection have beeb tried but it didn't seems to work.

Our end users came up with the solution to Sika-flex a .060 ABS panel to the bottom, leading edges of our unit and their vehicle to act as a balistic shield.
