• Both AISI 316L and T91 exhibited weight gains, and an oxide scale formed on the surface of specimens
• This oxide layer prevented further attack induced by dissolution
• T91 shows an oxide scale thicker and more uniform than AISI 316L
• Sensors for oxygen activity measurement have been qualified

EPICA project
Ice core drilling in Antarctica
• The main objective of EEuropiean PProject for IIce CCoring in AAntarctica is to drill two new deep ice cores in Antarctica to obtain full documentation of the climatic and atmospheric record changes in the past 500,000 years
The first core was drilled at Dome Concordia in the Indian Ocean sector of the East Antarctic plateau. The perforation, started in 1997, reached the depth of -3201.03 m in January 2003.
The control of the Epica drill at Dome-C is made by an electronic system that has been developed by the ENEA people of Brasimone Research Center.
EPICA project
Ice core drilling in Antarctica
The second core was drilled in Dronning Maud Land, in the Atlantic sector of Antarctica. The perforation, started in 2001, reached the depth of -1564.80 m in January 2003.
