Properties and applications of electroless nickel

Knoop microhardness values range from 500 to 720 compared to only 150 - 400 HK 100. Furthermore, of very special interest is the effect of heat treatment. The hardness of electrodeposited nickel decreases significantly on heat treatment due to recrystallization and grain growth. However, heat
