Musiyano wekuumbwa kwezvinhu
Cobalt-based alloys inoshandisa cobalt (Co), chromium (Cr), molybdenum (Mo), nezvimwewo sezvinhu zvikuru, izvo cobalt inotora chikamu chepamusoro, uye imwe simbi (Fe), carbon (C) nezvimwe zvinhu zvinowedzerwawo; nickel-based Iyo alloy inoshandisa nickel (Ni) sechinhu chikuru, uye inowedzera chromium (Cr), molybdenum (Mo), mhangura (Cu), titanium (Ti), niobium (Nb) nezvimwe zvinhu.
Processability misiyano
Cobalt-based alloys ane basa rakanaka rekuomesa uye annealing kupfavisa zvivakwa, uye zviri nyore kugadziriswa kuita akasiyana maumbirwo. Iwo akakodzera machining zvikamu uchishandisa cobalt-based alloys. Nickel-based alloys ane yakanaka processability uye ari nyore kugadzira, extrusion uye rotor kugadzira kugadzirisa, uye akakodzera machining zvikamu. Kuvandudza uye kuvandudzwa kwemakina emagetsi anomhanya-mhanya uchishandisa nickel-based alloys.
1. Kurapa kupisa: Zvose zvinopisa zvinopisa zvinoda kurapwa kwekupisa. Ivo vese vanotora yekupisa kurapwa sisitimu yakasimba mhinduro kurapwa + kuchembera kurapwa. Kuoma kwehutano hwekugadzirisa kupisa kwakafanana.
2.Weldability: Ose ari maviri epamusoro-tembiricha alloys ane yakanaka weldability. Munguva yebrashi seal welding, kupisa kuri nyore kuunganidza uye kukonzera deformation. Inokurudzirwa kushandisa cobalt-based materials, iyo ine high thermal conductivity, yakasimba thermal conductivity, diki yekuwedzera coefficient, uye duku deformation. , iyo welding fusion simba iri nani.
3.Kushandura kugadzirisa: Kugadzirisa kutendeuka kunogutsa kunogona kuitwa.
Ose ari maviri epamusoro-tembiricha alloys ane yakanaka processability.
Kusiyana kwemaitiro
1.Corrosion resistance:
Cobalt-based alloys ine yakanakisa kupfeka kusagadzikana, corrosion resistance uye yakakwirira tembiricha zvinhu, uye inogona kuchengetedza kushanda kwakadzikama munzvimbo dzakanyanyisa dzakadai seasidhi yakasimba, alkali yakasimba, tembiricha yepamusoro uye kudzvanywa kwepamusoro, uye inokodzera kugadzira zvikamu zvinoda kumira mitoro yakakura uye yakanyanyisa nharaunda;
Nickel-based alloys ane yakanaka corrosion resistance uye anogona kuchengetedza kugadzikana uye kutendeseka mumhando dzakasiyana dzehuori. Ivo zvakare vane yakanakisa yepamusoro-tembiricha zvivakwa uye vanogona kuchengetedza yakakwirira simba uye kuomarara munzvimbo dzepamusoro-tembiricha. Asi haina kukodzera kune yakanyanya corrosive acidified media.
2.Thermal kugadzikana: Cobalt-based alloys ane zviri nani kudziya kwepamusoro-soro pane nickel-based alloys uye anogona kushandiswa pakudziya kwakanyanya pamusoro pe1200 ° C kwenguva yakareba, nepo nickel-based alloys inogona kungoshandiswa kutenderedza 1000 ° C. Cobalt-based alloys ane yakakwirira kunyunguduka uye kupisa conductivity, kudiki kwekuwedzera kwemafuta mushure mekupisa, uye zvine zvakanakira mukugadzikana kwekupisa; nickel-based alloys ane zviri nani kupikisa oxidation uye corrosion, asi munzvimbo dzepamusoro-tembiricha, cobalt The base alloy ine zviri nani yakakwirira-tembiricha oxidation resistance uye yakakwirira-tembiricha corrosion resistance.
3.Mechanical simba: Cobalt-based alloys ane yakanakisa yepamusoro-tembiricha simba uye yakanaka yekupisa kuneta kuramba, nepo nickel-based alloys ine yakanakisa ductility uye processability, asi yavo yepamusoro-tembiricha simba uye nekupisa kuneta kuramba yakaderera zvishoma kune cobalt-based alloys. . Pakupisa kwekamuri, simba recobalt-based alloys rakadzikira zvishoma, asi kureba kwakakura; nickel-based alloys ane simba repamusoro, asi ane brittle, uye anofanirwa kushandiswa nekuchenjerera munzvimbo dzine simba. Pakupisa kwepamusoro, kana tembiricha iri 650°C, nickel-based alloys ane simba repamusoro, asi zvakare ane brittle, uye anowanzoputsika kana akashandiswa mumamiriro ezvinhu. Kana tembiricha yakwira kusvika 900°C, nickel-based superalloy haichagoni kushandiswa, nepo diamond-based superalloy ichine rimwe simba.
4.Mechanical kuoma: Iko kunonzi kuomarara ndiko kugona kwechinhu kupikisa deformation. Iko kuoma kwe nickel-based alloys yakaderera pane iyo cobalt-based alloys mune ese tembiricha.
Usage
Cobalt-based alloys inowanzoshandiswa kugadzira zvikamu zvakasiyana-siyana uye zvikamu pasi pekupfeka-kusagadzikana, kusagadzikana-kuora, kupisa-kupisa uye kusingagadziriswi mamiriro ekushanda; nickel-based alloys anoshandiswa zvakanyanya mundege, aerospace, simba, marine, kuchengetedzwa kwezvakatipoteredza uye mamwe minda, kunyanya Kugadzirwa kwezvinhu zvakakosha senge turbine blades uye makamuri anopisa mumajini emhepo.
