Reduction Expansion Synthesis of Chromium and Nickel Metal Coatings
Abstract
This thesis represents a step forward in a program to provide the Department of Defense (DOD) alternative approaches to the production of anti-corrosion metal coatings. Specifically, a method was developed to make micron thick but irregular nickel coatings on iron, based on Reduction Expansion Synthesis (RES) chemistry. Previous success using RES processes to make sub-micron nickel, iron, and alloy particles provided a general direction to the program and led to the successful protocol. Physical mixtures of nickel (II) oxide particles and urea were used to create a paste. The paste was coated on an iron foil, which was briefly heated at 1100C in an inert atmosphere. Also described are partially successful attempts to develop a RES protocol to chrome coat iron. This is motivated by the need to eliminate the carcinogenic intermediate in the current electrolytic technology, hexavalent chromium.
