Is the Nikasil plating on the cylinder walls hard?

Why does Nikasil plating improve DFV oil consumption?
The reported improvement in oil consumption of the DFV with ‘Nikasil’-treated Al-alloy cylinders may have been a consequence of more rapid and complete bedding-in of the piston rings, which is what is thought to have occurred in the Porsche 912 engine. If this then reduced combustion gas blow-by a power gain would have been observed.
