Izvo zvakanakira nekuipira kwehupfu-simbi isina simbi uye nzira dzayo yekukunda

    Inofananidzwa nesimbi isina tsvina inogadzirwa neyakajairika nzira yekunyungudika, hupfu hwesimbi simbi isina chinhu ine zvakanakira padhuze nemambure kuumba, kukwirira kwepamhando yepamusoro, kushandiswa kwepamusoro kwezvinhu, uye chimiro cheunifomu. Instrumentation nemamwe maindasitiri.

    Nekudaro, hazvisi izvo kuti hupfu hwesimbi simbi isina simbi hwakakwana. Nekuda kweiyo pores irimo, michina zvivakwa, kupfeka kuramba uye ngura kuramba kwehupfu simbi isina simbi yakaderedzwa zvakanyanya, izvo zvinokanganisa zvakanyanya kushandiswa kweichi chigadzirwa.

    Nekudaro, zvidzidzo zvakaratidza kuti angangoita ese ehupfu simbi simbi isina simbi inowedzera nekuwedzera kuwanda, chero bedzi huwandu hwehupfu hwesimbi isimbi isingawedzerwe uye porosity yacho yaderedzwa, inogona kutora chinzvimbo chakakosha mukuvandudza mashandiro ehupfu simbi isina simbi. .

    Icho chikonzero nei paine zvakawanda zvisina maturo mukati mehupfu simbi isina simbi ine zvakawanda zvine chekuita nemaitiro eiyo solid phase sintering, saka vashandisi vakatanga kuitsiva iyo neakasimba solid chikamu chikamu chemvura sintering, kuitira kuti isina simbi simbi pre -alloy powder yakaumba mvura panguva yechando. Phase, mvura chikamu chinozadza iyo pores nekuyerera kuwedzera kuwanda uye kuita kwemuviri sintered. ,

    Kusiyana neyakajairwa mvura-chikamu sintering, yakanyanya-yakasimba-chikamu mvura-chikamu sintering ndiyo sintering yeakafanogadzirwa-akapetwa hupfu, uye inogara iri imwechete chikamu panguva yekukanganisa sintering. Iyo tintering tembiricha ichagara iri pakati peyakaomeswa-chikamu uye mvura-chikamu. Uye zvakare, izvo zvidimbu zvinogona kugadziriswazve pasi pechiito cheiyo capillary simba rechikamu chemvura, uye iyo sintered muviri unogona kuitwa wakakora neiyo mvura chikamu chikamu kuyerera uye kuwanda kuendesa.

    Uye zvakare, nekuwedzera yakakodzera inosimbisa chikamu, imwe yedzakakosha nzira dzekuvandudza mashandiro ehupfu simbi yesimbi isina simbi, kunyanya kuomarara kwayo uye kurira kweabrasion, yakagadziridzwa zvinoenderana.

Batanidza kuchinyorwa ichi: Zvakanakira nekukanganisa kwesimbi yesimbi yeupfu simbi

Dzokorora Chirevo: Kana pasina mirairo yakakosha, zvinyorwa zvese zviri pasaiti ino ndezvepakutanga. Ndokumbira uratidze kwakabva kudhindazve: https://www.cncmachiningptj.com/, thanks!
