Abstract

The invention relates to the field of film preparation, in particular to an arc ion plating arc source which controls the movement of arc pit with dynamic magnetic field. The dynamic controlled arc ion plating arc source is provided with a dynamic control magnetic field generator, a target and a target base; the target is arranged on the target base; the dynamic control magnetic field generator consists of a main control magnetic field generator and an auxiliary magnetic field generator; the main control magnetic field generator is arranged behind the target and is coaxial with the target; the auxiliary magnetic field generator is arranged around the main control magnetic field generator. In the invention, arc-shaped magnetic fields which are dynamically distributed are formed on the target surface with the help of the cooperation of the two magnetic field generators, so as to improve the discharge form and work stability of the arc pit, control the movement track of the arc pit, improve the erosion evenness and target utility rate of the target, reduce the emission of large target particles and prepare high-quality film.

Description

technical field [0001] The invention relates to the field of thin film preparation, in particular to an arc ion plating arc source which uses a dynamic magnetic field to control arc spot movement. Background technique [0002] Arc ion plating is one of the most important technologies in industrial coating production and scientific research. Due to its simple structure and process, high ionization rate (70%-80%), high incident particle energy, and good diffraction, it can achieve low temperature A series of advantages such as deposition have enabled the rapid development and wide application of arc ion plating technology, showing great economic benefits and industrial application prospects. [0003] Arc ion plating is a coating technology based on the principle of gas discharge plasma physical vapor deposition. This technology relies on the local high temperature of the arc spot generated on the surface of the cathode target in the vacuum coating chamber, so that the cathode...
