Aluminum Alloys: Properties uye rwekushanda nesimbi

Aluminum - kudiwa zvikuru sezvo simbi pakuvaka, uyewo mune dzimwe pazvinoitwa kwevanhu. Zvisinei, mune yayo yakaisvonaka muchimiro rinoshandiswa chaizvo kashoma. Inonyanyoshandiswa kushandiswa aruminiyamu alloys.

alloys All inogona kukamurwa Kudzingwa uye vachibata. The mhando yokutanga kugadzirwa nevanhu utsotso uye alloys nokuda mukugadzira yechipiri mhando rakaiswa kuvafurira. Kukanda aruminiyamu alloys kazhinji akapa aruminiyamu remubatanidzwa pamwe nesilicon. nesimbi akadaro yakasimba, vane yakakwirira ngura nemishonga, akavezwa zvakanaka. Kana yakabikwa alloys, pakati pavo inozivikanwa ndiye duralumin, iyo mamiriro ndiko aruminiyamu, magnesium uye mhangura. Izvi simbi waya iri kugadzirwa, Profile, jira, tepi. Process chiwanikwa anogona kupiwa angambosvika.

Properties ose aruminiyamu alloys zvinogona rakakamurwa mumuviri, zvemaziso uye makemikari. Panyaya mumuviri ehupfumi, ivo alloys vane anenge zvakafanana arambe achirema sezvo aruminiyamu pacharo. Vane simba mukuru, izvo zvinogona kukwikwidzana titanium uye simbi. Asi pano zvinofanira kucherechedzwa kuti utsotso tembiricha iri chiwanikwa iri diki (ndiko madhigirii 200). Zvinokosha kucherechedza kuti aruminiyamu alloys vane zvakanaka chafariz conductivity, zvinoshamisa kuitisa Magetsi welded zvakanaka uye husingakwanisi ngura, kunyange yakaisvonaka aruminiyamu, zvivako izvi dzakakwirira zvikuru.

Pamusoro zvemaziso ehupfumi, vanova wakakwidzwa muwanze mwero doping. Nechipiriso aruminiyamu alloys inoshandiswa kuvaka zvivako yakaderera uye unosvikirwa loading. Zvinofanira kucherechedzwa kuti zvivako zviri alloys vari kunyanya zvakachinja pashure muchidziisa kune imwe tembiricha, izvo anosarudza uye anoshandisa.

Sezvo chiwanikwa asati kushandisa kudiwa ribude, uye pakusika chaizvo mazano alloying zvinhu zvinofanira welded, unofanira kuteerera chokwadi chokuti nomoto pamusoro aruminiyamu alloys ane zvimwe zvinhu. Masero ane zvimwe zvinetso:

- zvakaoma alloys vari welded nokuti oxide firimu inooneka pamusoro pemvura simbi (kazhinji zvinosvibisa ari musono, uye ichi kuzvirega zvichikanganisa kwomuzvarirwo alloying simbi kumicheto);

- the oxide firimu uye chiwanikwa pachayo dzakasiyana utsotso pfungwa, musiyano zvinogona nouchapupu;

- kubva vachikanda aruminiyamu chiwedzerwa zvakakwirira zvakakwana, mushure Welding simbi anogona zvakakomba akaremara;

- alloys vane refu turnover, saka Welding dzenzvimbo kungaitwa simbi.

Nokuti nomoto alloys Anonyanyowanika kushandiswa kabhoni kana simbi electrodes. The kwacho chiri kuitwa ne kuramba kwazvino pakatarisana polarity. Asati atanga basa basa chidimbu kubatwa acetone kana benzine uye akachena simbi bhurasho. To nani yepamusoro nomoto yakapfuura, zvinokosha kuti vakuchidzire welded zvikamu kune akafanorongerwa tembiricha (200 madhigirii). Kuti tiwane musono zvakanaka pashure nomoto anofanira haachandidi zvishoma nezvishoma.
