Background technology
Piezoelectric ceramics is a kind of ceramic material that mechanical energy and electric energy can be carried out conversion mutually; This functional material in actual use, needs to be processed into certain article shape, and metallizes to the designated surface region of ceramic body, then through hyperpolarization, makes piezoelectric vibrator.
Effects on surface is needed to carry out roughening treatment before piezoelectric ceramics surface metalation, to improve ceramic surface and adhesive force of metal layer; The method of roughening treatment is generally chemical corrosion method, piezoelectric ceramic piece is carried out immersion treatment in an acidic solution, then cleaning, drying.This chemical corrosion method can make the surface of piezoelectric ceramic piece obtain alligatoring, but there is a lot of drawback, in immersion process, corrosive liquid can infiltrate into the surface of whole potsherd, and can corrode to certain depth, thus causing the surface texture of piezoelectric ceramic piece to be seriously damaged, the adhesive force on metal level and ceramics surface is poor.
Above-mentioned chemical roughen method also needs the corrosion-resistant fixing and clamping device preferably of preparation in actual application, and process is comparatively complicated.
Summary of the invention
For above-mentioned Problems existing, the object of this invention is to provide a kind of piezoelectric ceramics method for coarsening surface.
The object of the invention is to be achieved through the following technical solutions:
A kind of piezoelectric ceramics method for coarsening surface, comprises the following steps:
(1) barreling: choose the bulge that a kind of draw ratio is greater than 2, and 100-120 object quartz sand; Then by piezoelectric ceramic piece, quartz sand, water according to the ratio of 1:1:1, join in this bulge; Under guarantee good seal can not produce the prerequisite of leaking, bulge is placed between two turning cylinders, sets rotating speed and the time of turning cylinder, allow bulge rotate with axle;
(2) clean, dry: after barreling terminates, piezoelectric ceramic piece is taken out, be positioned in ultrasonic cleaning tank to surpass and wash 80 minutes, utilize the surface of supersonic wave cleaning machine to piezoelectricity ceramics to clean, cleaned rear taking-up, lamination is dried, bake out temperature is 150 DEG C, 3 hours time;
(3) high annealing: be stacked on aluminium oxide flat board by the piezoelectric ceramic piece after drying, then put into silver ink firing stove and carry out high annealing, peak temperature is set as 750 DEG C, piezoelectric ceramic piece proceeds to from fire door the All Time that stove tail goes out and controls to be 3 hours; So far, piezoelectric ceramics surface coarsening completes.
Beneficial effect of the present invention: what the present invention adopted the alligatoring on piezoelectric ceramics surface is that Physical carrys out treatment surface, fundamentally avoids the destruction of chemical corrosion liquid to piezoelectric ceramics surface strength; After barreling completes, employing ultrasonic cleaning method is cleaned goods, can ensure that attritive powder can not remain in product surface; The use of high annealing makes the bond strength of piezoelectric ceramics surface particles higher.High according to the adhesion numerical value between the piezoelectric ceramics surface after the inventive method alligatoring and metal level, and uniformity is good.
Detailed description of the invention
The following examples can illustrate in greater detail the present invention, but do not limit the present invention in any form.
Embodiment 1:
(1), barreling: choose length 40 centimetres, diameter is 15 centimetres, the bulge that wall thickness is 3 millimeters, and 100-120 object quartz sand; Then by piezoelectric ceramic piece, quartz sand, water according to the ratio of 1:1:1, join in this bulge; Be placed in two rotating shafts getting ready in advance after tentatively being shaken up by mixture in bulge, start allows bulge roll between the axles, and speeds control is 12 revs/min, and the time is 1.5 hours;
(2), cleaning, oven dry: after barreling terminates, piezoelectric ceramic piece is taken out, be positioned in ultrasonic cleaning tank to surpass and wash 80 minutes, utilize the surface of supersonic wave cleaning machine to piezoelectricity ceramics to clean, cleaned rear taking-up, lamination is dried, bake out temperature is 150 DEG C, 3 hours time;
(3), high annealing: be stacked on aluminium oxide flat board by the piezoelectric ceramic piece after drying, then put into silver ink firing stove and carry out high annealing, peak temperature is set as 750 DEG C, and piezoelectric ceramic piece proceeds to from fire door the All Time that stove tail goes out and controls to be 3 hours; So far, piezoelectric ceramics surface coarsening completes.
Adhesive force examination at random is carried out after room temperature is naturally cooled to the piezoelectric ceramic piece completing surface coarsening with said method, the steps include: the circular pattern printing diameter 10mm with silk screen on piezoelectricity ceramics surface, the high temperature sintering type silver slurry of the silver slurry use 650 degree of printing, drying 20 minutes in an oven with 150 degree after printed pattern, ensures that the pattern that electronic silver paste is printed is dried completely; Afterwards, it is carried out high temperature sintering in silver ink firing stove, peak temperature 650 degree of insulations 10 minutes.Then, carry out the printing of welding resistance protection pattern, printing method is: use the circular pattern that serigraphy pad is diameter 2 millimeters, the welding resistance green oil of the region beyond pattern covers, to ensure systematicness and the accuracy of welding disk pattern, welding resistance green oil uses thermosetting or the fast green oil of light; After above-mentioned steps all completes, electric wire and silver layer weld together with Pb-free solder by the welding zone of 2 millimeters; Then leave standstill and within 20 minutes, use tensiometer to measure adhesive force in vertical direction later, get 10 and test, following table 1 be classified as adhesive force index corresponding to this coarse surface (unit: N):
Table 1: by the adhesive force index of the piezoelectric ceramic piece after the inventive method alligatoring
| 1# | 2# | 3# | 4# | 5# | 6# | 7# | 8# | 9# | 10# |
| 45 | 46 | 44 | 45 | 45 | 44 | 46 | 45 | 44 | 46 |
