ALEXANDRIA, Va., Sept. 30 -- United States Patent no. 12,428,688, issued on Sept. 30.

"Methods for modifying surface properties using exothermic reactive powder mixtures" was invented by Nishkamraj U. Deshpande (Novi, Mich.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Various methods are provided to produce welded structures resistant to hydrogen induced cracking (HIC), improve wear resistance, reduce manufacturing steps including pre/post weld treatments, and improving corrosion resistance. Exemplary methods include using exothermic reactive powder mixtures on as-welded hot surface(s) during weld cooling which generate rapid exothermic reaction melting and hydrogen removal which results in reduction of hy...
