Ipleyiti yeKhabhoni ekumgangatho oPhakamileyo
Ipleyiti yentsimbi engenakutyiwa ligama eliqhelekileyo lepleyiti yensimbi engenasici kunye nepleyiti yentsimbi ekwaziyo ukumelana neasidi.Yaphuma ekuqaleni kwale nkulungwane.Ukuphuhliswa kwepleyiti yensimbi engenasici iye yabeka izinto ezibalulekileyo kunye nesiseko sobugcisa kuphuhliso lwamashishini anamhlanje kunye nenkqubela phambili yesayensi kunye nezobuchwepheshe.Kukho iintlobo ezininzi zeepleyiti zensimbi ezingenasici ezineempawu ezahlukeneyo.
Ngokuthe ngcembe yenze iindidi ezininzi kwinkqubo yophuhliso.Ngokwesakhiwo, yahlulwe yangamacandelo amane: ipleyiti yensimbi engenasici ye-austenitic, ipleyiti yentsimbi ye-martensitic (kubandakanya ipleyiti yensimbi engenasici), ipleyiti yensimbi engenasici yeferritic, kunye nepleyiti yensimbi engenasici ye-austenitic kunye ne-ferritic duplex?
Ngokweyona khemikhali iphambili kwipleyiti yentsimbi okanye izinto ezithile kwipleyiti yentsimbi, yahlulwe yaba yintsimbi ye-chromium, ipleyiti ye-nickel ye-chromium, ipleyiti ye-nickel ye-chromium ye-molybdenum, ipleyiti yentsimbi ephantsi-carbon, i-molybdenum ephezulu. ipleyiti yensimbi engenasici, ipleyiti yensimbi engenasici, njl.
Ngokweempawu zokusebenza kunye nokusetyenziswa kweepleyiti zentsimbi, zahlulahlulwe zibe yipleyiti yensimbi engenasici, ipleyiti yesulfuric acid, ukumelana nepleyiti yensimbi engenasici, ipleyiti yentsimbi engatyiwa ngumhlwa, ipleyiti yensimbi engenasici, ukuqina okuphezulu kwentsimbi, njl.
Ngokweempawu ezisebenzayo zepleyiti yensimbi, yahlulahlulwe ibe yintsimbi ephantsi yobushushu obuphantsi, ipleyiti yentsimbi engenamagnetic, ukusika ipleyiti yensimbi engenasici, ipleyiti yensimbi engenasici, njl. Ukwahlula intsimbi yentsimbi ngokweempawu zesakhiwo sentsimbi, iimpawu zokubunjwa kweekhemikhali zentsimbi yensimbi kunye nokudibanisa kwezi zibini.Ngokuqhelekileyo yahlulahlulwe ibe yipleyiti yensimbi engenasici, ipleyiti yensimbi engenasici, ipleyiti yentsimbi yeaustenitic, ipleyiti yentsimbi ephindwe kabini kunye nemvula eyenza lukhuni ipleyiti yentsimbi, okanye ipleyiti yentsimbi engatyiwa yichromium kunye nepleyiti yenickel engenasici.
Izixhobo ze-Pulp kunye nephepha, umtshintshi wokushisa, izixhobo zomatshini, izixhobo zokudaya, izixhobo zokucubungula ifilimu, umbhobho, izinto zangaphandle zezakhiwo kwiindawo ezinxweme, njl.
Ukuxhatshazwa kwe-corrosion yensimbi engenasici kuxhomekeke kwi-alloy composition (i-chromium, i-nickel, i-titanium, i-silicon, i-aluminium, i-manganese, njl.) kunye nesakhiwo sangaphakathi.
Ngokwendlela yokulungiselela, inokwahlulwa ibe yi-hot rolling kunye ne-cold rolling.Ngokweempawu zesakhiwo sebakala lensimbi, inokwahlulwa kwiindidi ezi-5: uhlobo lwe-Austenitic, uhlobo lwe-AUSTENITIC FERRITIC, uhlobo lwe-ferritic, uhlobo lwe-martensitic kunye nohlobo lwe-precipitation lukhuni.
Ipleyiti yensimbi engenasici inomgangatho ogudileyo, iplastiki ephezulu, ukuqina kunye namandla omatshini, kwaye iyamelana nokubola kweasidi, igesi yealkaline, isisombululo kunye nolunye uhlobo lweendaba.Olu luhlobo lwentsimbi yealloyi ekungelula ukurusa, kodwa alunarusi kwaphela.Ipleyiti yensimbi engenasici inamandla okuxhathisa i-corrosion jikelele efana ne-nickel chromium alloy engazinzanga 304. Ukufudumeza ixesha elide kwiqondo lokushisa le-chromium carbide kunokuchaphazela ukuxhathisa kwe-corrosion ye-alloys 321 kunye ne-347 kwimithombo yeendaba eyingozi.
Isetyenziswa ikakhulu kwizicelo zobushushu obuphezulu.Ukusetyenziswa kobushushu obuphezulu bufuna ukuxhathisa okunamandla okuthintela ukubola kwe-intergranular kumaqondo aphantsi.
Kwinsimbi engenastainless, susa kuqala ulusu olumnyama nge-ng-9-1 chemistry, kwaye kwabo banebala leoli, susa kuqala i-oyile nge-nz-b yokucoca ukumkani Ulwelo, iqondo lobushushu 60 ~ 80 ℃, i-workpiece ixhonywe nge-anode, i-Da yangoku yi-20 ~ 15A / DM2, kunye ne-cathode yi-alloy ye-antimony alloy (kubandakanya i-antimony 8%) Ixesha: 1 ~ 10 imizuzu, i-Polishing → ukuhlamba ngamanzi → ukuhlutywa kwefilim nge-5 ~ 8% ye-hydrochloric acid (iqondo lobushushu begumbi: 1 ~ 3 imizuzwana) → ukuhlamba ngamanzi → futha yome.
