Abstract
The invention belongs to the technical field of vacuum coatings, and particularly relates to a vacuum coating machine. The vacuum coating machine comprises a cathode device, wherein the cathode device comprises a plurality of target materials; and each target material can be independently connected to an electric arc generator. The target material has a smaller volume, and a plurality of electric arc generators are applied; since a square target corresponding to the volume of the adopted target material is small, and each circular target is independently controlled by a plurality of electric arc generators to uniformly volatize, the produced coating metal particles are smaller than the square target; and thus, the coating has a more compact structure and has good binding force with a coated workpiece. Since the circular target has a small volume and a number of the target materials are used, the target materials of different materials can be used for production and development of composite coatings and diverse coatings in technical production, and the process is high in changeability and flexibility.
Description
Technical field
The invention belongs to the vacuum coat technical field, particularly relate to a kind of vacuum-coating machine.
Background technology
The side's of being target cathode apparatus system of vacuum-coating machine employing at present; Square target 1 volume in side's target cathode apparatus system is all bigger; The standard that could effectively use based on target is to be as the criterion according to the partial-depth that has evaporated on the target, when certain local evaporation of target that uses during to certain bounding depth target will scrap and can't continue use.Because the target that square target 1 volume ratio is scrapped more greatly also can't carry out reusing so caused great raw-material waste after the reconditioning.Can't place a plurality of targets owing to square target 1 volume ratio than the limitation of large equipment cavity space in addition, so the system of the bigger user's target cathode of the more single limitation of target kind device can't carry out the production technique of compound coating, diversification coating.Once more, user's target system is because the target volume ratio is bigger, and relative vaporator rate is slow during arc generator 2 evaporation targets, and therefore the metallics that is evaporated is relatively thicker can't obtain the very high coating of compactness.
Summary of the invention
(1) technical problem that will solve
The technical problem that the present invention will solve is: a kind of target utilization rate of raw materials and coating quality of improving is provided, and can carries out the vacuum-coating machine of compound coating and diversification coating.
(2) technical scheme
In order to solve the problems of the technologies described above, the present invention provides a kind of vacuum-coating machine, comprises casing, cathode assembly and arc initiation device, and said cathode assembly connects arc generator, and said cathode assembly comprises a plurality of targets.
Wherein, each target all connects an arc generator separately.
Wherein, target is circular target.
Wherein, the diameter of target is 55mm～70mm.
(3) beneficial effect
Technique scheme has following advantage: target volume ratio of the present invention is less has used a plurality of arc generators; Because the target volume counterparty target that adopts is little and have a plurality of arc generators to control each circle target separately evenly so the coating metal particle side target produced of volatilization is littler by it; This be since in the target volume ratio prior art that adopts square target little and have a plurality of arc generators to control the virtual voltage Current Control of each circle target on unit are separately more accurately to make it evenly so the coating metal particle side target produced of volatilization is littler; Thereby make coating structure finer and close, coating and coated workpiece adhesion are good.Because the quantity that the little target of circle target volume uses often can use the target of unlike material to carry out the production and the exploitation of compound coating and diversification coating in explained hereafter, the process variability handiness is big.
Description of drawings
Fig. 1 is the square target cathode device synoptic diagram that prior art vacuum-coating machine structure is used;
Fig. 2 is a square target cathode device synoptic diagram in the embodiment of the invention.
Wherein, 1: square target; 2: arc generator; 3: circular target.
Embodiment
Below in conjunction with accompanying drawing and embodiment, specific embodiments of the invention describes in further detail.Following examples are used to illustrate the present invention, but are not used for limiting scope of the present invention.
As shown in Figure 1, the cavity both sides of present embodiment vacuum-coating machine respectively are equipped with 4 miniature circular targets 3, and the diameter of circular target 3 is 63mm, and each circular target 3 connects an independently arc generator.Arc generator 2 anodal linking device cavitys, negative pole connects circular target 3.Adopt the steady-state evaporation of the mode may command target metal ion of an arc generator 2 corresponding circular targets 3.
Under high vacuum state, pass through heater heats cavity to certain temperature; The circular target 3 of arc initiation device action contact makes arc generator 1 instantaneous short circuit that connects circular target 3 positive and negative electrode produce electric arc to bombard circular target 3 surfaces, is evaporated out because electric arc has the target metal ion that very high energy bombarded.
An instance that uses the vacuum-coating machine in the foregoing description to carry out the coating operation: employed circular target 3 is the titanium target.In vacuum tightness is 5E-5mbar workpiece Heating temperature to 480 degree centigrade, gets into the coating step.Follow procedure is set and to be required titanium target on load voltage to-60V, electric current to rise to 18A, and the workpiece loading voltage of coating to+40V, electric current risen to 18A, and feed the 3 hours nitrogen coating time of 1000sccm.The actual coat-thickness that records is 2.3u after cooling and the release vacuum.
Because square target volume is little in the miniature circular target 3 volume ratio prior aries that adopt; And there is each circular target 3 of a plurality of arc generator 1 independent control allow its even volatilization; So thereby the littler coating structure that makes of the coating metal particle of producing is finer and close, coating and coated workpiece bonding force are good.
Than the vacuum-coating machine of prior art user target cathode equipment, use the present embodiment vacuum-coating machine after, to the coating bonding force, surface hardness is tested and is drawn bonding force and brought up to HF2 by original HF3.Surface hardness has been brought up to HV2000-2300 by HV1800-2000.
Drawing maximum ga(u)ge and minimum thickness through the detection to test sample different sites coat-thickness differs and is no more than 0.4u to draw after using round target cathode device the coat-thickness homogeneity thus relatively good.
According to process requirements, to the shape of target, the adjustment that quantity all can be done adaptation, for example the diameter of circular target can be 55mm～70mm.
Because circular target 3 volumes of the present invention are little, the quantity that target uses is many, in explained hereafter, can use the target of unlike material to carry out the production and the exploitation of compound coating and diversification coating, and the process variability handiness is big.Because circular target 3 thickness are thicker; When the new target that uses the circle target system arrives the use volatilization limit for the first time; Its top can be done and repair a die; Processing treatment is fallen the target top and is erose part because of target consumption, adds the utilization ratio that has effectively improved target corresponding to the copper billet of the condition of equivalent thickness that repairs a die thereby contrast new target thickness then in the bottom of the back target that repairs a die.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and replacement, these improvement and replacement also should be considered as protection scope of the present invention.
