Kunaya-Kuomesa Stainless Simbi iboka resimbi isina simbi alloys iyo inopinda mukupisa kwekupisa kunodaidzwa kuti kunaya kwemvura kuomesa kuwedzera simba nekuoma kwavo. Kuita uku kunosanganisira kuumbwa kwemafine precipitates (zvimedu zvidiki) mukati mesimbi ye microstructure, iyo inotadzisa kufamba kweiyo dislocation, zvichikonzera kuwedzera kwe mechanical properties sesimba nekuoma.
Zvikamu zvakakosha zveKunaya-Kuomesa Stainless Simbi:
High Strength and Corrosion Resistance: Kunaya-kuomesa simbi isina tsvina inochengetedza kusadzivirirwa kwekuora kwakafanana nemasimbi asina tsvina ukuwo uchiwana simba repamusoro kuburikidza nemaitiro ekupisa.
Kurapa Kupisa:
1.Solution Heat Treatment: Simbi inodziyirwa kusvika pakupisa kukuru (kazhinji kunosvika 1000 ° C kusvika 1100 ° C) kunyungudutsa zvinhu zvinosanganiswa (sealuminium, mhangura, kana niobium) kuita mhinduro yakasimba.
2.Kuchembera: Mushure mokudzima (kukurumidza kutonhora), simbi inochembera pane yakaderera tembiricha (inenge 500 ° C kusvika 700 ° C). Izvi zvinokurudzira kunaya kwekuomesa zvimedu zvinotadzisa kufamba kwedislocation, nekudaro kusimbisa zvinhu.
3.Composition: Kunaya- kwakaomeswa simbi dzisina tsvina dzinowanzo sanganiswa nezvinhu zvakaita semhangura, aruminiyamu, niobium, titanium, kana molybdenum, izvo zvinoita kuti kunaya kwenhanho dzakaoma dzinowedzera kusimba kwesimbi.
Magiredhi: Muenzaniso unozivikanwa wemvura-yakaomeswa nesimbi isina tsvina ndeye 17-4 PH simbi isina tsvina, ine iron, chromium, nickel, nemhangura. Mamwe mamakisi, senge 15-5 PH uye 13-8 Mo, anowanzo shandiswa mumashandisirwo anoda musanganiswa wesimba repamusoro uye kuramba ngura.
Applications: Kunaya-kwakaomeswa simbi dzisina tsvina dzinoshandiswa zvakanyanya mumaindasitiri uko kusimba kwepamusoro uye kuramba kwekuora kwakakosha, senge mu:
1.Muchadenga: Zvikamu zvendege, turbine blades, fasteners.
2.Medical: Midziyo yekuvhiya, kudyara.
3.Chemical processing: Mapombi, mavharuvhu, uye zvimwe zvikamu zvinoratidzwa munzvimbo dzakaoma.
4.Marine: Zvikamu zvakafumurwa kunharaunda dzemvura yemunyu.
1.Advantages:
Simba rakakwirira rinofananidzwa nemamwe masimbi emidziyo.
Kupokana kwakanakisa kune corrosion uye oxidation, kunyanya munzvimbo dzepamusoro-tembiricha uye dzine hutsinye.
Yakanaka formability uye machinability mune mhinduro-yakarapwa mamiriro.
2.Zvakashata:
Inogona kudhura kupfuura mamwe masimbi asina tsvina nekuda kwealloying zvinhu uye kugadzirisa.
Kuchembera pakupisa kwakanyanya kwenguva yakareba kunogona kukonzera embrittlement kana isina kunyatsodzorwa.
Muenzaniso Magiredhi eKunaya-Kuomesa Stainless Simbi:
1.17-4 PH (inozivikanwawo se630): Iine 17% chromium, 4% nickel, uye 4% mhangura. Iri giredhi nderimwe reanonyanya kushandiswa uye rinopa musanganiswa wezvakanaka zvemakina zvivakwa uye marara kuramba.
2.15-5 PH: Zvakafanana ne 17-4 PH asi zvine kusimba kwepamusoro zvishoma uye kusagadzikana kwekuora, inowanzoshandiswa mumaindasitiri emuchadenga nemakemikari.
3.13-8 Mo: Iine angangoita 13% chromium, 8% nickel, uye molybdenum, inopa yakanyanya kushushikana kuora kwekupwanya kuramba.
Muchidimbu, kunaya-kuomesa simbi isina tsvina zvinhu zvinogoneka zvakasiyana-siyana zvinosanganisa zvakanakira simbi isina ngura yekuramba kuita ngura neyakakwidziridzwa michina senge simba rakawanda, zvichiita kuti zvikodzere kudiwa kwekushandisa mumaindasitiri akawanda.
