Bhawa reSimbi Isina Kuomarara Inoomesa
Tsananguro pfupi:
Kuomesa kwezera, kunozivikanwawo se precipitation hardening, inzira yekurapa kupisa inovandudza simba nekuoma kwemamwe ma alloys, kusanganisira simbi isina ngura. Chinangwa chekuomesa kwezera ndechekukonzera kunaya kwezvidimbu zvitete mukati mesimbi isina ngura, izvo zvinosimbisa zvinhu.
Bhawa reSimbi Isina Kuomarara Inoomesa:
Mafoshoro zvinhu zvesimbi zvakagadzirwa nenzira yekufoshoro, apo zvinhu zvinopiswa zvobva zvapfurwa kana kudzvanywa muchimiro chaunoda. Mafoshoro esimbi isina ngura anowanzo sarudzwa nekuda kwekudzivirira ngura, simba, uye kugara kwenguva refu, zvichiita kuti akwanise kushandiswa zvakasiyana-siyana, kusanganisira mudenga, mafuta negasi, nezvimwewo. Mafoshoro akaita sebhawa imhando chaiyo yesimbi yakagadzirwa iyo inowanzova nechimiro chakareba, chakatwasuka, chakafanana nebhawa kana tsvimbo. Mafoshoro anowanzo shandiswa mukushandiswa uko hurefu hwezvinhu hwakatwasuka, hwakafanana nekuvakwa kwezvivakwa kana sezvinhu zvekugadzirisa.

Chii chinonzi Precipitation Hardening Stainless Steel?
Simbi isina tsvina inosimbisa mvura, inowanzonzi "simbi isina tsvina yePH," imhando yesimbi isina tsvina inopinda muchirongwa chinonzi kusimba kwemvura kana kusimba kwezera. Maitiro aya anowedzera hunhu hwezvinhu zvacho, kunyanya simba razvo nekuoma kwazvo. Simbi isina tsvina inonyanya kusimbisa mvura ndeye17-4 PH(ASTM A705 Giredhi 630), asi mamwe magiredhi, akadai se15-5 PH uye 13-8 PH, anowirawo muchikamu ichi. Simbi dzisina kusimba dzinosimbisa mvura dzinowanzo sanganiswa nezvinhu zvakaita sechromium, nickel, mhangura, uye dzimwe nguva aluminium. Kuwedzerwa kwezvinhu izvi zvinosanganisa mvura kunokurudzira kuumbwa kwemvura inotonhora panguva yekupisa.
Kuoma kwesimbi isina ngura kunoomeswa sei?
Simbi isingatsvi inoomesa simbi panguva yekukwegura inosanganisira matanho matatu. Pakutanga, zvinhu zvinogadziriswa nekupisa kwakanyanya, uko maatomu anonyunguduka, zvichigadzira mhinduro yechikamu chimwe chete. Izvi zvinotungamira pakuumbwa kwemanuclei akawanda kana "nzvimbo" pasimbi. Zvadaro, kutonhora nekukurumidza kunoitika kupfuura muganho wekunyunguduka, zvichigadzira mhinduro yakasimba yakawandisa mumamiriro ezvinhu anogona kuchinjika. Padanho rekupedzisira, mhinduro yakawandisa inodziiswa kusvika pakupisa kwepakati, zvichikonzera kunaya kwemvura. Zvinhu zvinozochengetwa mumamiriro aya kusvika zvaoma. Kubudirira kwekuoma kwezera kunoda kuti chimiro chealloy chive mukati memuganho wekunyunguduka, zvichiita kuti maitiro acho ashande zvakanaka.
Ndedzipi mhando dzesimbi dzakaomarara dzinoshandiswa pakunaya kwemvura?
Simbi dzinoomesa mvura dzinouya mumhando dzakasiyana-siyana, imwe neimwe yakagadzirirwa kusangana nezvinodiwa pakushanda kwayo uye pakushandisa. Mhando dzakajairika dzinosanganisira 17-4 PH, 15-5 PH, 13-8 PH, 17-7 PH, A-286, Custom 450, Custom 630 (17-4 PHMod), uye Carpenter Custom 455. Simbi idzi dzinopa musanganiswa wesimba rayo guru, dzinodzivirira ngura, uye kuomarara, zvichiita kuti dzikwanise kushandiswa mumaindasitiri akasiyana-siyana akadai semuchadenga, mota, zvekurapa, uye makemikari. Sarudzo yesimbi inoomesa mvura inoenderana nezvinhu zvakaita senzvimbo yekushandisa, mashandiro echinhu, uye zvinodiwa pakugadzira.
Kurongedza:
1. Kurongedza kwakakosha zvikuru kunyanya kana zvinhu zvichitumirwa kunze kwenyika, zvinhu zvinopinda nenzira dzakasiyana-siyana kuti zvisvike kunzvimbo yekupedzisira, saka tinonyanya kufunga nezvekurongedza.
2. Saky Steel inorongedza zvinhu zvedu nenzira dzakasiyana-siyana zvichibva pazvigadzirwa. Tinorongedza zvigadzirwa zvedu nenzira dzakasiyana-siyana, dzakadai se,
