Water Vapor Effects on the CMAS Degradation of Thermal Barrier Coatings
A new damage mechanism of CMAS degradation of TBCs involving delamination through the thermally grown oxide (TGO) has been observed on burner rig tests of EB-PVD thermal barrier coatings. This mechanism operat...

Fireside Corrosion of Alumina-Forming Austenitic (AFA) Stainless Steels
The performance of four alumina-forming austenitic alloys was tested in simulative fireside corrosion atmospheres. The alloys were exposed at 700 °C to gas atmospheres of oxygen with varying amounts of SO2 with t...

The Effects of Water Vapor on the Oxidation Behavior of Alumina Forming Austenitic Stainless Steels
The isothermal oxidation behavior of three alumina forming austenitic (AFA) stainless steels with varying composition was studied at 650 and 800 °C in dry air and gases which contained water vapor. The AFA all...

Specificity of Reinnervation and Motor Recovery after Interposition of an Artificial Barrier Between Transected and Repaired Nerves in Adjacency – An Experimental Study in the Rat
Non-specific re-innervation of target organs caused by misdirected axonal growth at the repair site is regarded as one reason for a poor functional outcome after peripheral nerve transsection and repair. This...

Effects of Insulin-like Growth Factor-1 in Motor Nerve Regeneration After Nerve Transection and Repair vs. Nerve Crushing Injury in the Rat
Despite highest standards in nerve repair, functional recovery following nerve transection still remains unsatisfactory. Non-specific re-innervation of target organs are regarded as one reason for a poor func...
