Electroless nickel-phosphorous coatings with high thermal stability

摘要

Electrolessly plated Ni—P amorphous coatings having an increased magnetic transformation temperature and ultra smooth surface are achieved employing a plating bath containing Al and/or Cu ions. Embodiments include electrolessly depositing an amorphous Ni—P coating exhibiting a magnetic transformation temperature of at least 330° C. proximate a laser textured protrusion.
