Waya yeKovariwaya yesimbi ine simba shoma, inozivikanwa zvikuru nekuda kwehunhu hwayo hwakasiyana hwekuenzanisa kupisa.

Inotamba basa rakakosha mumaindasitiri ane hunyanzvi hwakanyanya senge zvemagetsi, zvemuchadenga, uye zvekushandisa pakurapa. Gwaro iri rinopindura mubvunzo mukuru wekuti waya yeKovar chii uye rinotsanangura mashandisirwo ayo akakosha, pamwe chete nemhinduro dzedu dzewaya dzeKovar dzemhando yepamusoro.

1. Chii chinonzi Kovar Waya?

1.1 Tsananguro Yepakati

Waya yeKovar iwaya yesimbi-nickel-cobalt alloy yakanyungudutswa ne vacuum-melted, yakagadzirirwa kudzora kupisa zvakanyanya.

Chinhu chikuru chakanakira girazi reborosilicate neceramics ndechekuenzanisa nekupisa kwegirazi reborosilicate nemidziyo yesimbi, zvichiita kuti rivharwe zvakanaka.

1.2 Kuumbwa Kwemakemikari Kwakajairika

Waya yeKovar ine chimiro chakanyatsodzorwa kuti ive nechokwadi chekuti inoshanda zvakanaka:

- Simbi (Fe): 53-54% (chiyero)

- Nickel (Ni): 28.5-29.5%

- Cobalt (Co): 16.8-17.8%

Zvinhu zvinotevedzana (Mn, Si, C) zvinongogumira mukati me0.5% max chimwe nechimwe.

1.3 Mitemo Yakakosha & Mazita

Inoenderana nezvinodiwa nenyika dzese kuti ive nechokwadi chekuti zvese zvinoshandiswa zvinoenderana.

- ASTM F15 (chiyero chikuru chezvigadzirwa zveKovar alloy)

- UNS K94610, Werkstoff Nr. 1.3981 (zvimiro zvepasi rose)

Inozivikanwawo se4J29 mumitemo yeChinese, inogona kuchinjwa neNilo-K mune dzimwe nzvimbo.

2. Hunhu Hukuru hweKovar Wire

2.1 Kuwedzera Kwekupisa Kwakaderera Uye Kwakagadzikana

Kuwanda kwayo kwekupisa (4.6-5.2×10⁻⁶/℃, 20-400℃) kunoenderana negirazi reborosilicate zvakakwana.

Izvi zvinobvisa kuputika kwekushushikana panguva yekupisa nekutonhodza, zvichiita kuti zvive nechokwadi chekuvharwa kwakavimbika.

2.2 Kugona Kugadziriswa Kwakanaka Kwazvo

Ine ductility yakanaka uye inogona kukweverwa muwaya dzakapfava, kukotama, uye kusungirirwa zviri nyore.

Yakakodzera kudhirowa kunotonhora, kudhirowa, uye nzira dzakasiyana-siyana dzekuwedera (argon arc, laser welding).

2.3 Kupisa Kwakanyanya & Kugadzikana kweHemetic

Inoramba ichishanda zvakanaka pakupisa kusvika ku450℃, ine poindi yekunyunguduka ye1450℃.

Inogadzira zvisimbiso zvisingapindi mhepo zvine magirazi/ceramics, zvakakosha pakushandisa vacuum uye kuvimbika kwakanyanya.

3. Waya yeKovar vs. Waya dzeAlloy Dzakafanana: Tafura Yekuenzanisa

Tafura iri pazasi inoratidza zvakanakira waya yeKovar kupfuura waya dzeconstantan necupro nickel:

4. Waya yeKovar Inoshandiswa Sei? Maitiro Ekushandisa Makuru

4.1 Kurongedza Kwemagetsi & Semiconductor

Inoshandiswa sewaya dzinoshandiswa pakugadzira machubhu evacuum, matransistors, madiode, uye macircuit akabatanidzwa.

Inogonesa kuvharwa kwemhepo nemidziyo yekudzivirira ngura yegirazi, ichidzivirira zvikamu zvemukati kubva kuhunyoro nekusvibiswa.

4.2 Ndege neNdege

Inoshandiswa muzvinhu zvemagetsi zvendege uye muzvishandiso zvekutaurirana nesatellite.

Kugadzikana kwayo pakupisa kunodzivirira kushanduka-shanduka kwakanyanya kwekushisa munzvimbo dzemuchadenga.

4.3 Midziyo Yekurapa

Inoshandiswa mumasensa ekurapa, michina yekuongorora, uye muzvinobatanidza zvinopinda mukati.

Inosangana nezvinodiwa zvakasimba zvekushandiswa kwemishonga uye kuvimbika kwayo.

4.4 Midziyo yeOptical & Vacuum

Inoshandiswa muzvisimbiso zvegirazi-kubva-kusimbi zvemafiber ekuona, machubhu e microwave, uye michina ye X-ray.

Inovimbisa kuti mhepo haipindi uye kuti kupisa kunoenderana nehurongwa hwemaoptical hwakanyatsonaka.

5. Zvigadzirwa Zvedu zveKovar Wire: Mhinduro Dzakavimbika dzeZvaunoda

5.1 Magadzirirwo Akazara

Inofukidza giredhi yakajairika (4J29/Kovar) ine dhayamita yewaya kubva pa0.10mm kusvika 5.0mm.

Inowanikwa muzvidimbu, makoiri, kana urefu hwekucheka, zvichienderana nezvinodiwa neASTM F15.

5.2 Mabasa Akagadzirwa Nemunhu

Ipai dhayamita dzewaya dzakagadzirirwa iwe uye marapirwo epamusoro (plating, oxidation) zvichienderana nezvinodiwa zvekuvhara.

Gadzirisa mhinduro dzekushandisa zvinhu zvidiki nemazvo kana maodha makuru emaindasitiri.

5.3 Kudzora Hunhu Zvakasimba

Kuyedzwa kwe100% usati wasvika, kusanganisira kuyedzwa kwekuwedzera kwekupisa, kuumbwa, uye dhayamita.

Kugadzirwa kwechinhu chakanyungudutswa ne vacuum kunoita kuti chishande zvakaenzana uye chive chakachena zvakanyanya.

6. Mhedziso

Waya yeKovar iwaya yesimbi isingatsiviwi ine simba shoma, inotsanangurwa nekugona kwayo kuenderana nekupisa uye kuvhara mhepo.

Kushandiswa kwayo zvakanyanya mumagetsi, mundege, uye muminda yekurapa kunoratidza kukosha kwayo uye kuvimbika kwayo.

Waya yedu yeKovar yemhando yepamusorozvigadzirwa zvinoshandisa zvizere mabhenefiti aya. Kana uchida waya yesimbi inovharwa zvakanaka kana kuti isina kuwedzera zvakanyanya, taura nesu kuti uwane mazano akakodzera iwe pachako uye rutsigiro rwehunyanzvi.
