ews from Research and Technology Institutes Worldwide This column informs JTST readers of activities in research and technology institutes active in the field of thermal spray technology. Technical overviews help the reader to understand the primary focus of the institution and the needs driving their thermal spray research and development. Getting to know the research interests and professional experience of our thermal spray colleagues allows us to better recognize experts in specific fields of study. Knowledge of institutional expertise is important for developing complementary partnering relationships to increase the fundamental understanding of thermally sprayed materials and increase the quality and breadth of practical applications. This column includes articles giving an overview of current activities or a focus on a significant breakthrough. To submit an article for this column, please contact Kendall Hollis, JTST Associate Editor at: Los Alamos National Laboratory, P.O.

Thermal Spray Research at Los Alamos National Laboratory Thermal spray research at Los Alamos National Laboratory (LANL) is focused on meeting U.S. national needs in the areas of toxic/hazardous materials, high temperature oxidation resistant materials, high stress tolerance materials, reactive molten metal containment materials, net-shaped spray-formed parts, and the evolving coating needs of U.S. national security programs. LANL is a multidiscipline research laboratory operated for the U.S. Dept. of Energy. The primary mission of LANL is performing research and development to meet U.S. national security needs. LANL is spread over 110 km2 of the Pajarito Plateau in the Jemez Mountains of north central New Mexico. Thermal spray R&D at LANL is part of the Materials Science and Technology (MST) division. Thermal spray activities are focused on meeting internal LANL needs and providing unique research facilities for use in the national interest. As part of the MST division, the emphasis of thermal spray R&D is on understanding the interaction between materials processing, properties, structure and performance as in the materials tetrahedron
Journal of Thermal Spray Technology
proposed by Merton Flemings in his 1989 National Research Council report titled Materials Science and Engineering for the 1990s. The thermal spray activities are divided up into two categories: beryllium and non-beryllium. The high hazards inherent in handling and processing beryllium in the particulate form have necessitated a specially designed facility for the beryllium work. The beryllium thermal spray activities are carried out in the Beryllium Technology Facility (BTF), which is dedicated to beryllium processing. The BTF ventilation and particulate control enclosures are designed to keep airborne beryllium exposures well below an action level of 0.2 lg/m3, which is an order of magnitude below the U.S. Occupational Safety and Health AdministrationÕs permissible exposure limit of 2 lg/m3.
