Properties and applications of electroless nickel
electrolytic nickel. Electroless nickel, therefore, provides a more effective barrier coating in protecting a substrate from corrosive attack. Heat treatment of nickel-phosphorus deposits can cause significant changes in properties and structure. X-ray dif-fraction examination shows substantial crystallinity and
