Zeziphi iibholithi ezilungele ubushushu obuphezulu?

Iibholiti ezisetyenziswe kwizicelo eziphezulu zokushisa kufuneka zikwazi ukumelana nokushisa okuphezulu ngaphandle kokulahlekelwa iimpawu zabo zomatshini okanye ingqibelelo. Iindidi ezininzi zeebholiti kunye neziqhoboshi ziyilelwe ubume bobushushu obuphezulu, kubandakanya:

1. I-Alloy Steel Bolts: Iibholiti ezenziwe ngensimbi ye-alloy, njenge-ASTM A193 iBanga le-B7, zifanelekile kwizicelo zokushisa eziphezulu. Ezi bholiti ziphathwa ubushushu ukunika amandla alungileyo kunye nokuxhathisa kokurhubuluza kumaqondo obushushu aphezulu.

2. Iibhotshi zensimbi ezingenasici: Amabakala athile ensimbi engenasici, afana ne-310 yensimbi engenasici, ayaziwa ngokuchasana nokushisa okuphezulu. Ezi bholiti zinokuxhathisa okulungileyo kwe-oxidation kwaye zigcina amandla azo kumaqondo aphezulu.

3. I-Inconel bolts: I-Inconel yintsapho ye-nickel-chromium-based high-temperature alloys eyaziwa ngokuba namandla aphezulu okushisa kunye nokumelana ne-oxidation. Iibholiti ze-inconel zifanelekile ukuba zisetyenziswe kwiindawo zokushisa ezigqithisileyo ezifana ne-injini yegesi kunye nokusetyenziswa kwe-aerospace.

4. Iibholiti ze-Titanium: I-Titanium kunye ne-titanium alloy bolts zilula ngobunzima kwaye zinamandla amahle kumaqondo aphezulu. Ngokuqhelekileyo zisetyenziswa kwi-aerospace kunye nezicelo zokulungiswa kweekhemikhali apho ukuxhatshazwa kweqondo lokushisa eliphezulu kuyadingeka.

5. Iibholithi zetsimbi eziphikisayo: Iibholithi ezenziwe ngeentsimbi ezikhanyelayo ezifana ne-molybdenum, tantalum, kunye ne-niobium zifaneleke kakhulu kwiindawo eziphakamileyo zobushushu obuphezulu, njengeziko lokufunxa kunye nokuveliswa kwe-semiconductor.

Xa ukhetha iibholithi kwizicelo eziphezulu zokushisa, kubalulekile ukuqwalasela uluhlu oluthile lobushushu, iimeko zokusingqongileyo kunye neemfuno zemishini yesicelo. Ukongezelela, ukufakela okufanelekileyo kunye nokuqwalaselwa koyilo lwe-fastener kubalulekile ekuqinisekiseni ukusebenza kwexesha elide kunye nokuthembeka kweebholithi kwiindawo eziphezulu zokushisa.

Ngaba ubushushu buchaphazela amandla okuqina?

Ewe, ubushushu bunokuchaphazela ngokubonakalayo ukomelela kwesixhobo. Kwiimeko ezininzi, amandla okuqina ezinto eziphathekayo ayancipha njengoko ubushushu bukhula. Le nto ibonakala ngokukodwa kwiintsimbi kunye ne-alloys, kodwa iyasebenza nakwezinye izinto.

Impembelelo yeqondo lobushushu kumandla e-tensile iphenjelelwa zizinto ezahlukeneyo, kubandakanywa ukubunjwa kwezinto, i-microstructure, kunye nobukho bezinto ze-alloying. Nazi iingongoma ezibalulekileyo ekufuneka uziqwalasele:

1. Izinto zeDuctile: Izinto ezininzi ze-ductile, ezifana ne-carbon steel, zilahlekelwa amandla obunzima njengoko ubushushu bukhula. Oku kungenxa yokwanda kokushukuma kokuphazamiseka ngaphakathi kweleti yekristale yemathiriyeli kumaqondo obushushu aphezulu, nto leyo enokukhokelela ekuchaphazelekeni okukhulu kwi-deformation kunye nokunciphisa amandla.

2. Iimathiriyeli ezinqabileyo: Izinto ezithile, ngakumbi iialloyi ezithile kunye neeseramikhi, zinokubonisa ukuziphatha okuntsokothileyo ngobushushu. Umzekelo, ezinye izixhobo ezibhityileyo zinokufumana ukonyuka kumandla okuqina kumaqondo obushushu aphakamileyo ngenxa yotshintsho kwindlela yokuziphatha yokwaphuka.

3. I-alloys yobushushu obuphezulu: Ezinye ii-alloys zobushushu obuphezulu, ezifana nezo zisetyenziswa kwi-aerospace kunye nezicelo zokuvelisa umbane, zenzelwe ngokukodwa ukugcina amandla abo okushisa kumaqondo aphezulu. Ezi alloys zenzelwe ukuxhathisa ukuthambisa kunye nokugcina iimpawu zabo zomatshini kwiindawo eziphakamileyo zokushisa.

4. I-Creep: Ukongeza ekubeni nefuthe elithe ngqo kumandla okuqina, amaqondo obushushu aphezulu nawo anokubangela ukurhubuluza, okukukonakaliswa kancinci kwezinto phantsi komthwalo oqhubekayo. I-Creep inokunciphisa ngakumbi amandla okuqina esixhobo ngokuhamba kwexesha kumaqondo obushushu aphezulu.

Kubalulekile ukuqaphela ukuba ukuziphatha okuthe ngqo kwamandla okuqina kwemathiriyeli njengomsebenzi wobushushu kuxhomekeke kukwakheka kwayo, ukusetyenzwa kwayo, kunye nesicelo esicetywayo. Xa kuyilwa amacandelo okusetyenziswa kwiindawo ezinobushushu obuphezulu, kubalulekile ukuqwalasela ifuthe elinokubakho lobushushu kumandla obunzima bezinto ezisetyenzisiweyo.

Isishwankathelo, ngelixa amandla okuqina ezinto eziphathekayo angachaphazeleka yiqondo lokushisa, uhlobo oluchanekileyo lwesi siphumo luxhomekeke kwizinto eziphathekayo kunye neempawu zayo ezithile. Ukuqonda indlela izinto eziziphatha ngayo phantsi kweemeko ezahlukeneyo zokushisa kubalulekile ekusebenzeni okuthembekileyo kwamacandelo abunjineli kwizicelo eziphezulu zokushisa.
