Kupisa kurapwa nzira

Mazhinji acho anoshandiswa muaruminiyamu alloy mutoro masero, ayo anoitwa mushure mekunge isina chinhu ichigadziriswa kuita elastic zvinhu, kunyanya kusanganisira reverse quenching nzira, kutonhora uye kupisa kutenderera nzira uye inogara tembiricha kuchembera nzira.

(1) Reverse kudzima nzira

Iyo inonzi zvakare yakadzika kutonhora uye nekukurumidza kupisa nzira muChina. Isa iyo aluminium alloy elastic element mu liquid nitrogen pa -196 ℃, chengetedza tembiricha kwemaawa gumi nemaviri, wobva waipfapfaidza nemhepo itsva yekumhanya kana kuiisa mumvura iri kufashaira. Nekuti kushushikana kunoitwa nekutonhora kwakadzika uye nekukurumidza kupisa kuri kwakapesana, ivo vanodzima mumwe nemumwe kunze uye vanozadzisa chinangwa chekuburitsa kwasara kushushikana. Muedzo unoratidza kuti kushushikana kwasara kunogona kudzikiswa ne84% nekushandisa liquid nitrogen-high-speed steam method uye ne50% nekushandisa liquid nitrogen-boiling water method.

(2) kutonhora uye kupisa kutenderera nzira

Iyo nzira yekutonhora uye inopisa bhasikoro kugadzikana kurapwa ndeye-196 ℃ × 4 maawa / 190 ℃ × 4 maawa, iyo inogona kuderedza yakasara kushushikana neanenge 90%, uye ine yakagadzikana dhizaini dhizaini, yakakwirira kuramba kune micro-plastiki deformation uye yakanaka dimensional. kugadzikana. Mhedzisiro yekuburitsa kushushikana kwasara iri pachena. Kutanga, kupisa kwekufamba kwesimba reatomu kunowedzera, kukanganiswa kwelatiti kunoderera kana kunyangarika, uye kushushikana kwemukati kunoderera kana kupisa. Iyo yakakwira tembiricha yekumusoro, iyo yakakura kufamba kwekupisa kwemaatomu, kunowedzera kunaka kwepurasitiki, iyo inonyanya kuburitsa kushushikana kwasara. Chechipiri, nekuda kwekudyidzana pakati pekushushikana kwekupisa uye kusara kunetseka kunokonzerwa nekupisa uye kutonhora tembiricha gradient, inogoverwa zvakare uye kushushikana kwakasara kunoderedzwa.

(3) Kugara tembiricha kuchembera nzira

Kugara tembiricha kuchembera kunogona kubvisa kushushikana kwasara kunokonzerwa nemachining uye kushushikana kwasara kunounzwa nekupisa kurapwa. Kana LY12 yakaoma aruminiyamu alloy yakura pa200 ℃, hukama pakati pekusarira kusagadzikana kusunungurwa uye nguva yekuchembera hunoratidza kuti kushushikana kwasara kunogona kuderedzwa neanosvika makumi mashanu muzana mushure mekubata kwemaawa makumi maviri nemana.
