Patent of the Month: September 2020

Superconformal Nickel Deposition for Hole Filling, Patent 10,508,358

Technology Description

NIST has patented a process of depositing metal filling called, “electodeposition” to fill up structures like pinholes in metal tubes in steam boilers without leaving air pockets or “seams” between the depositing metal and the structure.  Electodeposition automatically occurs when an additive to the metal fillings falls below a predetermined concentration level.
