Abstract

The invention relates to a multi-stage magnetic field straight pipe magnetic filtration and pulsed bias compounded electrical arc ion plating method, and belongs to the technical field of material surface treatments. In the prior art, plasma transmission efficiency is low and pulsed bias can not completely remove large particles due to applying of magnetic filtration on an arc source. A purpose of the present invention is to solve problems in the prior art. The method comprises: 1, connecting a workpiece to a pulsed bias power supply, connecting an electrical arc ion plating target source to a target power supply, and connecting a multi-stage magnetic field straight pipe magnetic filtration device in front of the target source; 2, carrying out thin film deposition, wherein work gas is introduced until achieving 0.01-10 Pa when a pressure in a vacuum chamber is less than 10<-2> Pa, the pulsed bias power supply is opened, a pulsed bias amplitude value, frequency and a duty ratio are adjusted, the target power supply is opened, plasma is generated, the multi-stage magnetic field straight pipe magnetic filtration device is opened, removal of large particles and efficient transmission of the plasma in the magnetic filtration device are achieved, process parameters are adjusted, and a thin film with no large particle defect is rapidly produced; and 3, adopting a single-stage magnetic field to combine direct current / pulsed bias to obtain a thin film with a certain thickness.

Description

technical field [0001] The invention relates to an arc ion plating method combined with multistage magnetic field straight tube magnetic filtering and pulse bias voltage, belonging to the technical field of material surface treatment. Background technique [0002] Arc ion plating technology originated from the former Soviet Union in the 1960s. After the introduction and promotion of the technology by the United States, it was applied to the preparation of TiN hard film on the surface of the tool, which greatly improved the cutting performance and service life of the tool, and caused a lot of problems. A wide-ranging tool technology revolution has realized the industrialization of this technology. At the same time, arc ion plating technology has also been widely used in decorative films, high-temperature protective coatings and functional films. [0003] Arc ion plating has the advantages of high ionization rate (70-90%), fast deposition rate, dense and uniform film layer, h...
