1. Kuchengeta
Tungsten uye molybdenum zvigadzirwa zviri nyore kuita oxidize uye kuchinja ruvara, saka zvinofanirwa kuchengetwa munzvimbo ine hunyoro huri pasi pe60%, tembiricha iri pasi pe28 ° C, uye yakaparadzaniswa nemamwe makemikari.
Iyo oxides ye tungsten uye molybdenum zvigadzirwa zvinonyungudika mumvura uye zvine acidic, ndapota teerera!
2. Kusvibisa embrittlement
(1) Pakupisa kwepamusoro (padhuze nekunyunguduka kwesimbi), ichaita nemamwe masimbi (simbi uye alloys ayo, nickel uye alloys ayo, nezvimwewo), dzimwe nguva zvichikonzera kukanganisa kwezvinhu.Paunenge uchiita kupisa kwekupisa kwe tungsten uye molybdenum zvigadzirwa, kutarisisa kunofanirwa kubhadharwa!
Kupisa kupisa kunofanira kuitwa muvacuum (pasi pe10-3Pa), kuderedza (H2) kana inert gas (N2, Ar, etc.) atmosphere.
(2) Tungsten uye molybdenum zvigadzirwa zvichave zvakanyungudutswa kana zvasangana nekabhoni, saka usazvibate kana kupisa kunoitwa patembiricha iri pamusoro pe800°C.Asi molybdenum zvigadzirwa pazasi 1500 ℃, dhigirii embrittlement kunokonzerwa carbonization idiki kwazvo.
3. Machining
(1) Kupeta, kurovera, kuveura, kucheka, nezvimwe zve tungsten-molybdenum ndiro zvigadzirwa zvinogara zvichitsemuka kana zvichigadziriswa patembiricha yekamuri, uye zvinofanirwa kupiswa.Panguva imwecheteyo, nekuda kwekugadzirisa kusina kunaka, dzimwe nguva delamination inoitika, saka kupisa kupisa kunokurudzirwa.
(2) Zvisinei, molybdenum ndiro ichava brittle kana inopisa pamusoro pe1000 ° C, izvo zvichakonzera kuoma mukugadzirisa, saka kuchenjerera kunofanira kubhadharwa.
(3) Paunenge uchikuya tungsten uye molybdenum zvigadzirwa, zvakakosha kusarudza nzira yekukuya inokodzera zviitiko zvakasiyana.
4. Nzira yekubvisa oxide
(1) Tungsten uye molybdenum zvigadzirwa zviri nyore kuita oxidize.Kana maokisi anorema achida kubviswa, ndapota ipa kambani yedu kana kubata neasidhi yakasimba (hydrofluoric acid, nitric acid, hydrochloric acid, nezvimwewo), ndapota teerera paunenge uchishanda.
(2) Pamaokisi akapfava, shandisa mushonga wekuchenesa une mabrasives, pukuta nejira rakapfava kana chipanje, wozogeza nemvura inodziya.
(3) Ndapota cherechedza kuti metallic luster icharasika mushure mekugeza.
5. Kuchengetedza kwekushandisa
1Paunenge uchishandisa chigadzirwa, ndapota pfeka zvekudzivirira.
(2) Kuwanda kwe tungsten kunosvika ka2,5 kune iron, uye kuwanda kwe molybdenum kunosvika ka1,3 pane yesimbi.Huremu chaihwo hunorema kupfuura chitarisiko, saka kubata nemaoko kunogona kukuvadza vanhu.Zvinokurudzirwa kuita basa remanyorero kana huremu huri pasi pe20KG.
6. Kungwarira pakubata
Iyo tungsten uye molybdenum zvigadzirwa zve molybdenum plate vagadziri masimbi ane brittle, ayo anowanzo kuputika uye delamination;saka, paunenge uchitakura, chenjerera kuti usashandise kuvhunduka uye kudedera, sekudonha.Zvakare, kana uchirongedza, ndapota zadza nezvinhu zvinobata zvinovhundutsa.
