Raws li ib qho tseem ceeb ntawm cov cuab yeej siv tshuab, kev xaiv cov khoom siv rau cov khoom siv kho tshuab ncaj qha cuam tshuam rau cov cuab yeej kev ua tau zoo, lub neej ntev, thiab kev ua haujlwm ruaj khov.
Cov cuab yeej siv cuab yeej cuab tam suav nrog ntau yam khoom siv, uas tuaj yeem faib dav rau hauv peb hom tseem ceeb raws li cov xwm txheej sib txawv thiab cov kev xav tau ntawm kev ua haujlwm: cov khoom siv hlau, tsis yog{0}} cov khoom siv hlau, thiab cov khoom sib xyaw.
Cov khoom siv hlau yog hom khoom siv tshuab siv ntau tshaj plaws, feem ntau suav nrog cov hlau ferrous, tsis yog{0}}ferrous hlau, thiab lawv cov alloys. Ferrous hlau, xws li carbon steel thiab alloy steel, yog dav siv nyob rau hauv manufacturing qhov chaw uas tiv taus hnyav loads thiab cuam tshuam, xws li gears, shafts, thiab bearings, vim lawv siab zog, zoo toughness, thiab zoo heev machinability. Cov hlau uas tsis yog-ferrous hlau, xws li tooj liab thiab txhuas, thiab lawv cov alloys feem ntau yog siv los tsim cov khoom siv hluav taws xob thiab cov cua kub dissipation vim lawv cov hluav taws xob zoo heev thiab thermal conductivity thiab corrosion kuj. Tsis tas li ntawd, qee qhov tshwj xeeb alloys, xws li stainless hlau thiab titanium alloys, muaj kev siv dav hauv tshuaj, aerospace, thiab lwm yam kev lag luam vim lawv cov corrosion kuj thiab siab -kub tsis kam.
Tsis yog- cov ntaub ntawv hlau kuj tseem muaj txoj haujlwm tseem ceeb hauv cov cuab yeej siv tshuab, feem ntau suav nrog cov yas, roj hmab, thiab ceramics. Cov ntaub ntawv yas xws li polyethylene, polypropylene, thiab polyamide feem ntau yog siv rau hauv kev tsim cov ntsaws ruaj ruaj, rwb thaiv tsev cov khoom, thiab cov kav dej vim lawv lub teeb yuag, corrosion kuj, thiab yooj yim ntawm kev ua. Cov khoom siv roj hmab xws li cov roj hmab ntuj thiab cov roj hmab hluavtaws yog siv dav hauv kev tsim cov nplhaib sib khi thiab kev poob siab- nqus cov khoom vim lawv cov elasticity zoo, hnav tsis kam, thiab roj tsis kam. Cov khoom siv ceramics xws li alumina ceramics thiab silicon nitride ceramics feem ntau yog siv los ua cov cuab yeej txiav thiab hnav- cov khoom tiv taus vim lawv qhov siab tawv, kub tsis kam, thiab corrosion kuj.
Cov ntaub ntawv sib xyaw yog cov khoom siv tshiab uas tau tshwm sim nyob rau xyoo tas los no nrog kev txhim kho cov ntaub ntawv tshawb fawb. Lawv yog tsim los ntawm ob los yog ntau tshaj cov ntaub ntawv sib txawv los ntawm lub cev los yog tshuaj txoj kev thiab muaj superior zog tsis pom nyob rau hauv ib cov ntaub ntawv. Hauv cov khoom siv kho tshuab, cov ntaub ntawv sib xyaw xws li carbon fiber ntau thiab iav fiber ntau yog siv dav hauv kev tsim cov khoom sib sib zog nqus hauv aerospace, automotive manufacturing, thiab lwm yam kev lag luam vim lawv lub zog siab, lub teeb yuag, thiab corrosion kuj.
Tsis tas li ntawd, qee cov ntaub ntawv tshwj xeeb xws li siab - kub alloys thiab superhard cov ntaub ntawv kuj ua lub luag haujlwm tseem ceeb hauv cov khoom siv tshuab hauv cov chaw tshwj xeeb. High- kub alloys, xws li npib tsib xee-raws li alloys thiab cobalt-raws li alloys, yog dav siv nyob rau hauv kev tsim khoom ntawm siab- kub Cheebtsam xws li aero engines thiab roj turbines vim hais tias lawv muaj zoo heev mechanical zog thiab corrosion kuj nyob rau hauv high kub. Cov ntaub ntawv superhard, xws li pob zeb diamond thiab cubic boron nitride, yog siv los tsim cov cuab yeej txiav thiab abrasives vim lawv cov hardness siab heev.
