his article will investigate the main cause of the formation and spread of corrosion in the ACE industry and, more specifically, whether and to what extent cataphoresis can contribute to solving this problem.
Costs of corrosion The estimated costs arising from corrosion problems in the ACE field are about $ 250,000 per year, although some sources report even
72
higher figures. A large part of these costs is due to the presence of sharp edges and to the lack of adequate protection of such areas (Ref. opening photo). This is a very relevant
and important issue in the ACE sector, while it is less so in other industrial segments where the issue can be approached and partially solved with solutions that go beyond the coatings and their formulation.
The cataphoretic coating is the first protective layer to be applied and it is the one giving the surface most of the anticorrosion properties required.”

The cataphoretic coating is the first protective layer to be applied and it is the one giving the surface most of the anti-corrosion properties required. The other layers are therefore left
