Maliu mamanu ma oti lafoina faʻagasologa o metala paʻepaʻe oti uʻamea lafo faaiuga

Taimi: 2020-12-17 Hits: 23

Geometric design mo luga lelei faʻatonutonuina o metala paʻepaʻe metala paʻepaʻe castings oti

 

I le mamanu o metala paʻepaʻe lafo metala paʻepaʻe, i le mamao e mafai ai e aloese mai tauaso pu loloto loloto ma isi fausaga, o le mea lea, i le mamanu vaega, e le afaina ai le foliga vaaia ma le faʻaaogaina o le vaega, alavai gaioiga pu talafeagai fofo, kesi. I lenei auala, o le plating fofo e mafai ona lelei plated ma le faʻamalieina tikeri mafai ona faʻaititia.

 

Maliu mamanu ma oti lafoina faʻagasologa o metala paʻepaʻe oti uʻamea lafo faaiuga

 

O le laualuga o metala paʻepaʻe uʻamea filogia oti lafo o mafiafia vaega ma mafiafia o uiga 0.1 mm, ma o le vaega i totonu o porous fausaga. I le faʻagasologa o le fuafuaina o le oti ma le lafoina o le oti, o le laualuga o mea faigaluega e tatau ona lamolemole i le mea e gata ai le mafai, ma le faia o faʻaletonu e pei o taʻetaʻei, blowholes, malulu va, burr ma burr tatau ona faʻaititia.

 

O le mea lea, e tatau ona faia faʻamama masini. I lenei taimi, le pito i luga o le mafiafia vaega e tatau ona aloese mai ai, ina ia aloese mai le faʻaalia o le porous matrix, mafua ai faigata i le electroplating ma aʻafia ai le tulaga lelei o electroplating. Faʻalauiloa sooupu e masani ona faʻaaogaina i le metala paʻepaʻe metala oti lafo. Faʻalogo tatau ona totogi i le faʻaaogaina o le faʻasaʻoloto sooupu ma le demoulding.

 

Filifili mea o metala paʻepaʻe metala paʻepaʻe faaiuga castings

 

O mea e masani ona faʻaaogaina o metala paʻepaʻe e: 2znal43, 2znal41, 2znal40.5, 2znal4, o ituaiga e masani ona faʻaaogaina znal925 ma znal903, ae o le znal903 e sili atu i le znal925.

 

I se faʻaopopoga, o se vaega o le toe faʻaleleia mea e masani ona faʻaaogaina i le oti lafoina, o le vaega e tatau ona faʻatonutonuina i le 15%, sili atu le sili atu nai lo 20%. Aua e faigofie ona tuʻufaʻatasia ma isi vaega (pei o le silicon), o le faʻapipiʻi o le ufiufi e afaina. Mo le castings ma tele manatu faaalia, e sili atu le faʻaaogaina hydrofluoric acid mo faʻagaoioia togafitiga i le taimi o le electroplating.

 

Afi asiasiga o metala paʻepaʻe metala paʻepaʻe faaiuga castings luma electroplating

 

(1) Foliga Vaaia: siaki pe o iai ni taʻetaʻe, faʻaputuputu, maosiosi, pu ma isi faʻaletonu ogaoga luga o le avanoa. Ina ia iloa le tele o nei faaletonu, pe a mafai ona aveʻese i latou i auala masini (faʻalelei, faʻamamaina, ma isi), o le oloina gaioiga mafai ona faʻateleina.

 

(2) Mea asiasia: siaki le vasega o metala paʻepaʻe uʻamea filogia, malamalama i le vaega o toe faafoi mea, siaki le tulaga lelei o oti lafo vaega, tuu le workpiece i le ogaumu i le 100 ~ 110 mo le 30min, ma siaki pe o loʻo tupu mai luga.
