The nickel diamond coating NiDi is made up of two materials: electroless nickel (Ni-P) and diamond. Because of the electroless chemical method of deposition, nickel diamond coating covers all surfaces of the work piece with essentially perfect uniformity. A standard coating should contain 20 to 30 % diamond by volume with a thickness of around 20 μm. On wire samples several defects were identified by 3D optical microscopy and by SEM equipped with EDX analysis. The cause of the defects in electroless nickel plating can be divided into two main categories:chemistry problems and deposit problems.
