Brenham, Texas, [March 9, 2019]– REM Surface Engineering completes Phase I funding through the National Aeronautics and Space Administration’s (NASA) Small Business Innovation Research (SBIR) program. REM Surface Engineering’s proposal, “Internal/External Surface Finishing of Additively Manufactured IN-625 Components”, was awarded in June 2018 with submission of final reports and deliverables scheduled for February 15, 2019. REM successfully completed 100% of all objectives.  These deliverables include:

  1. Reducing the surface roughness to a 32 μ” RMS surface finish or lower;
  2. Removing 0.02 – 0.05” of material uniformly from the internal and/or external surface of geometrically complex Inconel 625 AM components in a 24-hour cycle;
  3. Eliminating surface defects that would otherwise result in reduced tensile and/or fatigue properties;
  4. Capable of surface finishing 100’s or 1000’s of components without excessive footprint requirement;
  5. Can potentially be automated, is scalable, and needs minimal operator interaction;

The right shows the progression of the surface texture through the surface finishing process.


REM has generated a new technology capable of uniformly processing IN-625 AM components and imparting improved fatigue/mechanical performance with greatly enhanced surface conditions.  Many REM Surface Engineering employees contributed to the project’s success including Dr. Agustin Diaz, Patrick McFadden, Nathan Michaud, Will Wirtz, Lane Winkelmann.
