Electroless nickel - ductility

 

By the ductility term is to be meant the elastic and plastic deformability of a coating.


As a measure of the ductility is regarded the break elongation in %. 

EN layers are Ni-P-alloys. They have smaller elongation values than galvanic Ni layers.

Fast deposited, bright coatings up to 0,5 % with phosphorus content of 5 to 8 %. Slowly deposited coatings up to 2 % with phosphorus content of 10 to 13 %.
