Description

A kind of pneumatic type arc initiation device of vacuum cathode arc evaporation source
Technical field
The utility model relates to a kind of pneumatic type arc initiation device of vacuum cathode arc evaporation source.
Background technology
The vacuum cathode arc deposited is that one of mainstream technology with the hard protective film is used and decorated to current ion plating tool and mould.Concrete coating process is as follows: the vacuum cathode arc evaporation source is arranged on the vacuum film coating chamber sidewall, it is indoor that the evaporation source front end penetrates Vacuum Deposition, plating material on it--target piece is facing the indoor workpiece to be plated of Vacuum Deposition, by the vacuum arc differential of the arc spot of arc initiation device at target piece surface ignition cluster, the high temperature of arc macular area and field cause the effect effect allows the target evaporation generate metal vapors, and be ionized into plasma body to spatial emission, be deposited as film at workpiece surface.
Arc initiation device is the indispensable integral part in cathodic arc evaporation source.At present the mechanical contact arc initiation device is adopted in domestic cathodic arc evaporation source mostly, has pneumatic and electronic two kinds.Fig. 1 is the structural representation of the present pneumatic arc initiation device of commonly using, and mainly is comprised of piston component 1-11, piston extension rod 1-4, striking pin 1-2, sealing insulator 1-6, dynamic seal 1-7, dynamic seal pressure pad 1-8 and piston component supporting member 1-10.Piston component 1-11 mostly is outsourcing piece.As shown in Figure 1, piston component supporting member 1-10 is vertically fixed on the arc evaporation source joint flange 1-5 outside to piston component 1-11, and piston extension rod 1-4 and the coaxial setting of piston component 1-11 are fixedly connected with both by connecting screw rod 1-9 on relative end face.Piston extension rod 1-4 front end passes the inboard that the upper perforate of arc evaporation source joint flange 1-5 enters arc evaporation source joint flange 1-5.Dynamic seal pressure pad 1-8, dynamic seal 1-7, sealing insulator 1-6 are sleeved on piston extension rod 1-4 successively.Wherein, sealing insulator 1-6 is arranged on arc evaporation source joint flange 1-5 outside tapping, dynamic seal 1-7 is inlaid in the outer face of sealing insulator 1-6, dynamic seal pressure pad 1-8 is fitted on described dynamic seal 1-7 and sealing insulator 1-6 by piston component strut member 1-10, to guarantee the stopping property between piston extension rod 1-4 and arc evaporation source joint flange 1-5.Striking pin 1-2 is installed in the front end of piston extension rod 1-4 by thrust screw 1-3, shaft-like with piston extension rod 1-4 form right angle, the front end of striking pin has the elbow towards target piece 1-1 surface.
Arc process is as follows: when piston component 1-11 setback, drive piston extension rod 1-4 and retreat, the elbow of the striking pin 1-2 that piston extension rod 1-4 front end connects touches target piece 1-1 surface.The target piece 1-1 in cathodic arc evaporation source connects the power cathode of evaporation source, and piston component 1-11 and striking pin 1-2 connect positive source, at striking pin 1-2 and target piece 1-11 Contact, flows through Short-Circuit High Current; Immediately, piston component 1-11 reversing motion, driving piston extension rod 1-4 and striking pin 1-2 travels forward, striking pin 1-2 front end elbow leaves target piece 1-1 surface, in this time of releasing, the place is concentrating very high current density in some protrusion tip of striking pin 1-2 and the former contact surface of target piece 1-1, and the electric arc that can ignite generates the electric arc differential of the arc spot of cluster.More than complete the arc process that once ignites.
