PERFORMANCE OF COMMERCIALLY PURE TITANIUM IN CORROSIVE SOILS

THE BEHAVIOR OF SPECIMENS OF TITANIUM TUBING WITH WELDED SEAMS IS REPORTED AFTER EXPOSURE IN THE SOILS AT SIX NATIONAL BUREAU OF STANDARDS CORROSION TEST SITES FOR EXPOSURES UP TO EIGHT YEARS. DATA SHOW THAT THE TITANIUM TUBING , AS WELL AS THE WELD AND HEAT AFFECTED ZONES, ARE UNAFFECTED BY CORROSION WITH RESPECT TO PITTING OR METAL ATTACK IN ANY OF THE SOIL ENVIRONMENTS TO WHICH THEY WERE EXPOSED. THE MECHANISM WHICH PROVIDES TITANIUM WITH SUCH EXCELLENT CORROSION RESISTANCE IS ATTRIBUTED TO THE FORMATION AND MAINTENANCE OF A STABLE AND PASSIVE OXIDE FILM OVER THE SURFACE. EVIDENTLY, THE PROTECTIVE OXIDE FILM ON TITANIUM IS MAINTAINED UNDERGROUND EVEN IN VERY POORLY AERATED SOIL ENVIRONMENTS, SUCH AS TIDAL MARSH. /AUTHOR/
