Magnetron sputtering apparatus manufactured by magnetic confinement magnetron sputtering method

The invention relates to a magnetic confinement magnetron sputtering method and a magnetron sputtering device prepared by use of the same. As the prior art adopts a balanced magnetron sputtering mode and an unbalanced magnetron sputtering mode, the target material utilization rate can only be raised to be between 20 and 35 percent even if permanent magnet movement or the transformation of a plurality of electromagnetic coil sets is adopted, and the prior art has the problems of complex structure and high processing cost. The magnetic confinement magnetron sputtering method forms a magnetic confinement magnetic field with the overall direction parallel to a target surface above the surface of a sputtering target. The magnetron sputtering device manufactured by use of the method comprises amagnet, a magnetic conductor, a substrate and the sputtering target, wherein contrary magnetic poles of the magnet are oppositely fixed on the sides of the sputtering target; the magnetic confinementmagnetic ...

Magnetorheologicai polishing liquid and preparation method thereof

The invention relates to a magnetic rheological polishing fluid and a preparing method for the fluid. The magnetic rheological polishing fluid comprises by volume magnetic particles 30-40%, pure water 45-55%, additive 5-10%, surface active agent 3-5% and polishing powder 5-8%.
