Problems solved by technology
At present, domestic manufacturers have the following disadvantages in rotating column arc ion plating: there are large particles on the sputtering target, which are difficult to handle, the utilization rate of the target is not good, and raw materials are wasted; the magnet is easily demagnetized after being soaked in high-temperature water for a long time. Affects the strength of the magnetic field; the driving device is a dynamic seal, which is prone to air leakage and has a short service life; the conductive contact of the lead wire is not good, and it is easy to arc.

Description
technical field [0001] The invention relates to the technical field of plasma surface vapor deposition, in particular to a novel rotating magnetron cylindrical arc target device. Background technique [0002] At home and abroad, vacuum coating has been widely used in machinery, electronics, energy, information and other fields, and in vacuum coating, production efficiency and quality are very concerned. Vacuum coating technology, also known as vapor deposition technology, mainly includes physical vapor deposition (PVD) and chemical vapor deposition (CVD). Physical vapor deposition refers to the method of vaporizing the plating material into atoms, molecules, or ionizing it into ions under vacuum conditions, using various physical methods, and directly depositing it on the surface of the substrate. Physical vapor deposition itself is divided into three types: : Vacuum evaporation coating, vacuum sputtering coating and vacuum ion coating have developed very fast in the past t...
