| Corrosion
resistance |
The electrochemical properties of this alloy were
evaluated in an electrochemical cell built according
to standards defined in ISO 10271.
The following results were obtained: |
| Eocp
= 72 mV |
Ep = 860 mV |
I300
= 0.21µA◦cm-² |
Ip = 4.1µA◦cm-² |
|
| The high
value of the breakdown potential (Ep 860 mV) with
the low current density at 300 mV (I300
= 0.21µA◦cm-²) indicate the excellent
corrosion resistance of this alloy. |
| Cytotoxicity
testing |
| Cytotoxicity
of KERAMIT 600 alloy has been evaluated according
to ISO 10993-5 standard, using the L-929 (mouse
fibroblasts) cell line. |
| Results
have confirmed the perfect cytocompatibility of
this alloy. Cells behaviour and function were definitely
similar to those measured in tests involving pure
gold, that is the paradigmatic non-toxic material. |
