Description
Technical field
The invention belongs to technical field of laser processing, is related to a kind of ultrafast laser that is suitable for and adds in the cavity parts such as blade
Work aperture and avoid the protective materials of ultrafast laser damage cavity part opposite walls after through hole and insert method.
Background technology
Laser punching is the engine thermal end pieces such as one of main application fields of Laser Processing, Laser Processing turbo blade
Air film hole is the typical case of hole fabrication techniques.In the past mainly using millisecond pulse Laser Processing blade air film hole, but aperture exists
Recast layer, even micro-crack, if the drilling on the turbo blade with thermal barrier coating, due to larger thermodynamic activity, easily lead
The defects of causing coating delamination, chip off-falling.Picosecond, femtosecond laser remove material there is non-thermofusible, heat affecting is minimum, because
This is suitable on turbo blade, is included on the turbo blade with thermal barrier coating processing high quality aperture, at present can be with
Machining small hole wall is realized without recast layer, micro-crack, heat affected area, coating is almost without thermic defect.
As millisecond laser punching, picosecond, femtosecond laser drilling also face asking for damaged blade inner cavity after laser via
Topic, as shown in Figure 1, therefore, it is necessary to avoid laser from directly acting on inner cavity opposite walls in blade inner cavity filling protective materials, this is anti-
Protective material has the characteristics that to avoid laser breakdown within a certain period of time, it is clear that the time is longer, and protection effect is better.
For millisecond laser punching, protective materials more ripe at present is polytetrafluoroethylene (PTFE), is applied in engineering.But
Ultrafast laser（Containing picosecond laser, femtosecond laser）Find that ultrafast laser easily penetrates polytetrafluoroethylene material, 1mm in drilling experiment
The thick material, time, that is, breakdown, effective protection when can not realize drilling to blade inner cavity opposite walls less than 1s, without
It is very serious using safeguard procedures, damage.
Can realize inner cavity effectively protection be to realize that ultrafast laser high quality hole fabrication techniques should in blade air film hole machined
Key, therefore, is badly in need of exploitation suitable for the protective materials of ultrafast laser drilling and inserts method.
The content of the invention
The purpose of the present invention：A kind of brand-new protective materials is developed, suitable for ultrafast laser drilling, avoids ultrafast laser from existing
Inner cavity opposite walls are damaged during drilling；It is easy to be filled in inner cavity and is easy to remove from inner cavity after completing drilling.
To achieve these goals, present invention employs following technical solution：
A kind of protective materials for avoiding ultrafast laser drilling damage cavity part opposite walls, including base material and adhesive, the base
Material is the spherical particle of aluminium oxide ceramics, and the component of described adhesive includes polyvinyl alcohol（PVA）And water, the polyvinyl alcohol
（PVA）Quality parts ratio with water is 12：100；
The spherical particle of aluminium oxide ceramics usually selects three kinds of specifications：Specification 1, diameter range：0.2~0.35mm；Specification 2,
Diameter range：0.4~0.6mm；Specification 3, diameter range：0.6~0.8mm；It can also be used in mixed way；
The selection principle of the spherical particle of aluminium oxide ceramics is：The larger specification of particle size is usually selected, when its is anti-breakdown
Between it is longer；But in the case of bore passages are less, such as within 1mm, bulky grain filling gap causes greatly protection effect on the contrary
Difference, on the premise of the anti-breakdown time meets the requirements, can be selected the less specification of particle size；
The effect of described adhesive is that the alumina ceramic grain bonds together；
Described adhesive is being 12 including quality parts ratio:On the basis of 100 polyethylene alcohol and water, it can also include：Quality
Number is 10 aluminium-hydroxide powder（AL(OH)3）And/or the titania powder that mass fraction is 10（TiO2）And/or quality
Number is 0.3 OP-10 surfactants；
The configuration step of described adhesive is：Two kinds of aluminium hydroxide, titanium dioxide powder stirrings are added in water；Addition polymerization ethene
Alcohol；Add OP-10 surfactants；Finally stir the mixture for uniformly.
Avoid the protective materials of ultrafast laser drilling damage cavity part opposite walls inserts method, is to fill out the protective materials
Enter the method for inner cavity of component, including：
Method one：By prepared adhesive and the spherical particle of base material aluminium oxide ceramics with 1 ︰ 2~1 of quality parts ratio：5 are mixed
Close, need the inner cavity protected with appropriate method such as manual expression or squeeze method etc., injection part after mixing, Gu
Change.
Method two：Appropriate method is taken such as to pour into by hand or vibrate injection the spherical particle of base material aluminium oxide ceramics,
Injection part needs the inner cavity protected, then adhesive is penetrated into inner cavity, adhesive is mixed with the spherical particle of aluminium oxide ceramics
Uniformly；80 DEG C -120 DEG C naturally dries again, or complete naturally dry are heated to, makes protective materials dry and cures.
Beneficial effects of the present invention：1st, different materials ultrafast laser damage threshold testing experiment is based on first, preferably, is configured
It is suitable for the protective materials of ultrafast laser drilling, has reached avoid ultrafast laser damage after through hole with cavity structure part
The effect of inner cavity opposite walls, the material of research and development have no report both at home and abroad；2nd, protective materials is realized to be easy to insert and out of blade
Removed in chamber：1）Protective materials base material has selected form of spherical particles aluminum oxide base material, has good mobility；2）It is configured with specially
Granular material is bonded and is solidified togather with adhesive, and original state is mushy stage after adhesive mixing, same tool
There is preferable mobility, suitably inject and fill up part irregular shape inner cavity, and realize close to tabular alumina ceramics material
The protection effect of material.
