Abstract

The invention discloses a bias voltage regulation and control aperture plate plasma immersion ionic deposition DLC method, and relates to a plasma immersion ionic deposition DLC method. The method aims at solving the problems that when an existing MPIID method is used for depositing a DLC film, the bonding force is poor, the performance of the film is not prone to being regulated and controlled, and the DLC film deposited on large or complex parts is uneven. The method includes the steps that (1) an aperture plate and a workpiece are arranged in a vacuum chamber, the workpiece is placed on a sample support in the aperture plate, the aperture plate and the workpiece are insulated, the aperture plate is connected with a aperture plate high-voltage pulse power source, and the workpiece is connected with a workpiece high-voltage pulse power source; (2) workpiece sputter cleaning is carried out; (3) plasma nitrogen treatment is carried out; (4) sputtering etching treatment is carried out; (5) a SiC transition layer is manufactured; and (6) a bias voltage regulation and control thin film is manufactured. The method is used for manufacturing the bias voltage regulation and control aperture plate plasma immersion ionic deposition DLC film.

Description

technical field [0001] The invention relates to a plasma immersion ion deposition DLC method. Background technique [0002] DLC (DiamondLikeCarbon) film has many excellent properties, such as low friction coefficient, high hardness and wear resistance, chemical inertness, optical transparency in the infrared spectrum range, low electrical conductivity and biocompatibility, which make DLC film have a wide range of applications. Application prospect. [0003] DLC films can be prepared by physical vapor deposition (PVD) methods (such as sputtering or arc evaporation) and plasma enhanced chemical vapor deposition (PECVD-PlasmaEnhancedChemicalVaporDeposition). PECVD technology is to connect a negative bias power supply to the workpiece, and use the glow discharge of hydrocarbon gas (such as acetylene or methane) to deposit DLC film. The laboratory generally uses radio frequency (rf-13.56MHz) power supply. The preparation of DLC by rf-PECVD is not easy for large-scale industrial...
