Don’t be Passive about Passivations

Don’t be Passive about Passivations

The hot-dip galvanizing on steel components is a very reactive material that is often given a surface treatment to inhibit oxidation from exposure to moisture and other constituents in the atmosphere. These treatments are referred to as “passivation treatments” and are applied to the zinc surfaces during the quenching process or soon after and before the surfaces begin to oxidize.

The hot-dip galvanizing on steel components is a very reactive material that is often given a surface treatment to inhibit oxidation from exposure to moisture and other constituents in the atmosphere. These treatments are referred to as “passivation treatments” and are applied to the zinc surfaces during the quenching process or soon after and before the surfaces begin to oxidize. These treatments are generally not expected to provide long-term protection of the zinc and therefore the galvanized steel is often specified to receive protective coatings to prolong the life of the zinc coating and to provide aesthetics.

Concrete Evaluation for Coating and Lining

Product Number: 41207-344-SG
Author: Robert G. Johnson
Publication Date: 2007
$20.00

Coating and Lining of Concrete requires an understanding of both new and existing concrete substrate conditions. New concrete must be evaluated for surface strength, cracking, and construction defects. In addition, existing concrete must be evaluated for mechanical damage, chemical contamination, and corrosion. Evaluation methods and equipment will be discussed.

Deriving Value from Coating Inspection Data

Product Number: 41207-301-SG

Significant quality control/quality assurance data is collected during industrial coating projects. Too often this data is surveyed for compliance with the contract requirements and then relegated to a file cabinet, never to be seen again. The paper highlights the types of coating inspection data collected and various “value-added” analyses which may be performed.

For several decades, engineered coatings have been used to protect steel from corrosion. Many formulas were made and tested for their ability to prevent corrosion. Changes in the formulas would include different resins, pigments, solvents and additives. In this paper, we will talk about three specific pigments, which are also commonly referred to as reinforcing pigments.
