Description

technical field [0001] The invention relates to the technical field of vacuum surface coating, in particular to a device and method for sputtering and depositing metal on the surface of a magnetic powder material. Background technique [0002] Magnetic powder materials are usually uniformly doped with metal atoms within the crystal and grain boundaries to improve their coercive force stability under special conditions such as high temperature. [0003] At present, the process of uniformly doping metal into the interior of the magnetic magnetic circuit crystal and the grain boundary is mainly to mix the magnetic material powder and the doped powder and ball mill, and then diffuse to the interior of the crystal after high temperature tempering to form a uniformly doped magnetic material. . However, the doped metal particles used in this method are tens to hundreds of nanometers, and it is difficult to obtain uniformly doped magnetic materials during powder mixing and heat tre...
