Nickel-plated hollow zirconium oxide microspheres (Ni-HZM)

Nickel-plated hollow zirconium oxide microspheres (Ni-HZM-8Y) stabilized with yttrium oxide are used for plasma spraying and as a filler for metal-ceramic materials.
Metal nickel deposited on the outer surface of hollow zirconium oxide microspheres ranges from 10% to 60% by weight of Ni, enabling plasma deposition modes to be tailored to create special-purpose protective coatings.
