The ElectroSpark Deposition (ESD) process was successfully used to transfer amorphous
material from an electrode to an amorphous substrate without crystallizing either material.
The resulting deposit was confirmed to be amorphous using X-ray diffraction. The deposit
shows hardness values of 508Hv±20 in comparison to the 514Hv±14 measured for the
substrate with no evidence of a heat affected zone. The growth rate appears to increase
linearly as a function of the number of layers deposited. The relationship between the …
