Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 30 November 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 30 March 2029.

Abstract

Corrosion is a major contributor to structural deterioration in steel structures, leading to increased maintenance costs and reduced reliability. Across the United States, tens of thousands of steel bridges are in poor or fair condition, primarily due to corrosion-related damage. This research project investigates the use of cold spray metal additive manufacturing as a method to restore corroded steel bridge…
