• Using a nondestructive test to qualify corrosive specialty gas cylinders
  of the gases contained in cylinders qualified via this QC technique and SEM analysis of qualified cylinders after 27 months of Cl2 gas service showed no degradation of the coating. References 1. T Ohmi et al., "Formation of Chromium Oxide on 316L Austenitic Stainless Steel," Journal of Vacuum...
• Stainless Steel
  One of the features that characterize stainless steels is a minimum 10.5% chromium content as the principal alloying element. Four major categories of wrought stainless steel, based on metallurgical structure, are austenitic, ferritic, martensitic, and precipitation hardening. Cast stainless-steel...
• Comparing the characteristics of surface-passivated and electropolished 316L stainless steel
  , AISI 316L stainless steel has an intrinsic corrosion resistance because of its ability to form a protective oxide or "passive" layer on its surface by alloying >12% chromium with iron, nickel, and molybdenum. This protective layer is thought to consist of a heterogeneous chromium oxide film (Cr...

• Copper-jacketed germ buster
  Staphylococcus aureus (MRSA) which are the source of many hospital-acquired infections. The findings are being put to the test at Selly Oak Hospital in Birmingham, England, Memorial Sloan-Kettering Cancer Center in New York City, the Medical University of South Carolina, and the Ralph H. Johnson VA Medical...
• Refractory Hard Metals
  for applications requiring wear resistance; the high-cobalt grades serve where impact resistance is required. Tantalum carbide and tungsten carbide combined in a matrix of nickel, cobalt, and/or chromium provide an RHM formulation especially suited for a combination of corrosion and wear resistance...
• New from the Fab Labs: Lightweight but Superstrong Parts
  stainless steel. Since the melted parts have a different thermal expansion than stainless steel, they just pop off with no need for cutting or sawing. Titanium and cobalt-chromium alloy work well with EBM and there is a continuously growing list of other materials that work as well. Arcam AB in Molndal...
• MICRO:Top 40 - Page 2 (Nov '99)
  . Measuring ~4000 A, the coating is chromium with a silicon dioxide overcoat that is free of visible voids, pinholes, and scratches. The optical coating works with most sensor technologies. Wafers are also available without optical coating. Coated and noncoated wafers are available at specified prices...
• A Probabilistic Approach to Modeling Microstructural Variability and Fatigue Behavior in ASTM F562 Medical Grade Wire (.pdf)
  Several previous studies have demonstrated the importance of constituent inclusion particle distributions on variability in observed fatigue lifetimes. Such models have often concentrated on crack growth behavior in standard test specimens such as single edge notch tension (SENT) geometries...
• The Effect of Surface Enhancement on the Corrosion Properties, Fatigue Strength, and Degradation of Aircraft Aluminum (.pdf)
  . The corrosion fatigue and pitting corrosion performance of 7475-T7351 aluminum. alloy is investigated for both SP and LPB treated test specimens. In all cases,. LPB provided greater resistance to pitting and SCC damage. Corrosion fatigue. life and damage tolerance were improved compared to the SP...
