Foreword
This standard is identical with ISO 4526.2004 "engineering metal coating layer nickel plating layer" (in English).
This standard is based on ISO 4526.2004 Translation drafted.
For ease of use, this standard made the following editorial changes.
--- Delete international standards foreword, preface increased our standards;
--- "This International Standard" be replaced by "this standard";
--- References to international standards corresponding to the national standards.
This standard replaces GB/T 12332-1990 "Metallic coatings Engineering nickel plating."
This standard and GB/T 12332-1990 compared to the main changes are as follows.
--- Increased introduction;

Introduction
Engineering nickel plating layer having a wide range of applications, such as increased hardness, wear resistance, corrosion resistance, bearing capacity, thermal oxidation resistance, corrosion fatigue
Labor performance and improve other surface properties. Electroplated nickel also works to repair worn or tolerance of machined parts and other metal
Combinatorial diffusion barrier layer. Engineering nickel plating layer containing nickel is generally higher than 99%, which is not commonly used additive Watts nickel or ammonia
Sulfonic acid plating nickel bath. Appendix A shows a typical bath composition, mechanical properties and operating conditions of the coating.
When the requirement to increase the hardness, improved abrasion resistance, improved electrical stress and enhance the deposition of leveling properties, may be added, such as silicon carbide, to the solution
