Evaluation of Abrasion-Resistant Metallized Coatings for Civil Works Applications

Abstract:

Vinyl coatings have been commonly used to protect U.S. Army Corps of Engineers hydraulic structures since the early 1950s. Under normal service conditions, vinyl coatings can protect the substrate for 30 years or longer. But vinyls exposed to very high abrasion fail completely in 12 to 24 months. The U. S. Army Construction Engineering Research Laboratory USACERL tested metallized coatings--much harder than conventional organic paints--in a highly abrasive environment to evaluate durability and corrosion resistance. Aluminum-bronze alloy, stainless steel, zinc, and zinc-aluminum alloy were applied by thermal spray to tainter gate No. 5 at Belleville Locks and Dam on the Ohio River. Results indicated excellent performance for the zinc and zinc-aluminum alloy coatings. However, aluminum-bronze and stainless steel coatings showed early signs of failure because of galvanic corrosion. AW
