About

Richard Smith

Dr. Richard J. Smith is a Professor of Physics in the Department of Physics at Montana State University. He received a B.A. in Physics from St. Mary's College, Winona, Minn., (1969) and a Ph.D. in Solid State Physics from Iowa State University (1975). After three years on a postdoctoral appointment at Montana State University, he joined the research staff at Brookhaven National Laboratory. He returned to MSU as a faculty member in 1980.

He is currently director and principal investigator in the Ion Beams Laboratory at MSU. Dr. Smith directs a group of several undergraduate and graduate students and postdoctoral associates in two separate programs funded by NSF and DOE (HiTEC). Research interests include: epitaxial growth at metal-metal interfaces, formation of intermetallic alloys at surfaces and interfaces, corrosion of metal surfaces, degradation of materials in solid oxide fuel cells, the absorption of hydrogen in metals, and ion-solid interactions including ion beam mixing, channeling, and nuclear reaction analysis. He is the author/co-author of over 100 publications and has served as PI on many federally funded projects. His teaching interests include instruction of introductory engineering physics classes and the development of improved upper division laboratories.

Project Summary: Advanced Surface Engineering for SOFC Components

Since the beginning of the HiTEC program at MSU, Dr. Smith’s program has consisted of a collaborative effort with Dr. Vladimir Gorokhovsky, Arcomac Surface Engineering Inc. of Bozeman, Mont., to use advanced surface engineering techniques to fabricate low-cost, corrosion resistant bipolar plates for SOFC stacks operating at temperatures near 800 degrees Celsius. The approach has been to use large-area filtered arc deposition technology (LAFAD) available from ASE to coat steel interconnect plates, and to characterize the performance of the plates by their area-specific resistance (ASR) in the group of Dr. Max Deibert (Chemical Engineering, MSU), and their oxidation and thermal stability using ion beam techniques in the group of Dr. Smith.

Initially, the emphasis was on designing a multilayer structure for the coatings, e.g. CrN/AlN nanolayers, that would reduce oxidation rates while maintaining good electron conduction and mechanical adhesion. Reduction of oxidation rates by more than an order of magnitude was achieved. Subsequently, the focus shifted to coatings consisting of CrAlON (oxynitrides). More recently, the group began fabricating and studying functional coatings consisting of a bond coat for adhesion, and a top coat for corrosion resistance and thermal stability. As issues of Cr volatility and degradation of stack performance received more attention, the group developed procedures for quantitative measurements of Cr volatility from steel surfaces using ion beam analysis. The group also uses nuclear reaction analysis (NRA) with isotopes of oxygen (18O) to measure oxygen transport during oxide scale growth and surface exchange rates for oxygen adsorption, e.g. at YSZ electrolyte surfaces.

Anticipating a need for thinner electrolytes in SOFCs operating at lower temperatures, the group initiated experiments to grow dense YSZ on porous YSZ anode material using magnetron sputtering and LAFAD processes. The facilities used by Dr. Smith’s group for this project include the ion beam laboratory at MSU, the ICAL facility at MSU, the Montana Microfabrication Facility at MSU, and the ion beam analysis laboratory at EMSL in Richland, Wash., as well as the growth facilities at ASE.
