Classification ntawm hnav resistant cov ntaub ntawv
Cov ntaub ntawv hnav-tiv taus yog cov chav kawm loj ntawm cov ntaub ntawv tshiab nrog tshwj xeeb hluav taws xob, sib nqus, kho qhov muag, acoustic, thermal, mechanical, chemical thiab biological functions. Lawv yog cov ntaub ntawv tseem ceeb rau cov ntaub ntawv thev naus laus zis, biotechnology, thev naus laus zis thev naus laus zis thiab lwm yam kev siv thev naus laus zis thiab kev tsim kho hauv tebchaws, thiab tseem ua lub luag haujlwm tseem ceeb hauv kev hloov pauv qee yam kev lag luam. Xws li kev ua liaj ua teb, tshuaj lom neeg kev lag luam, khoom siv hauv tsev thiab lwm yam ua lub luag haujlwm tseem ceeb. Muaj ntau hom kev hnav-tiv taus cov ntaub ntawv thiab ntau yam kev siv, thiab nws tab tom tsim ib pawg loj-tech high-tech industrial group, uas muaj kev lag luam dav heev thiab qhov tseem ceeb ntawm cov tswv yim tseem ceeb. Cov ntaub ntawv hnav-resistant tuaj yeem muab faib ua cov ntaub ntawv micro-electronic, cov khoom siv optoelectronic, cov ntaub ntawv sensor, cov ntaub ntawv cov ntaub ntawv, biomedical cov ntaub ntawv, ecological ib puag ncig cov ntaub ntawv, cov khoom siv hluav taws xob thiab cov khoom ntse (ntse) raws li kev siv ntawm kev ua haujlwm. Txij li thaum peb tau coj cov ntaub ntawv xov xwm hluav taws xob los ua cov khoom siv tshiab ib leeg, cov ntaub ntawv hnav-tiv taus tshiab hu rau ntawm no yog cov ntaub ntawv tseem ceeb hnav-tiv taus ntxiv rau cov ntaub ntawv xov xwm hluav taws xob.
Kev faib tawm ntawm cov khoom hnav-resistant:
(1) hnav-resistant steel series: siab manganese hlau (ZGMn13), siab manganese alloy (ZGMn13Cr2MoRe), ultra-siab manganese alloy (ZGMn18Cr2MoRe), nruab nrab, qis thiab siab carbon ntau alloy hlau (xws li ZG40SiMnCrMO thiab (ZG35Cr2MoNiRe) ;
(2) hnav-resistant cam khwb cia hlau series: siab chromium cam khwb cia hlau, nruab nrab chromium cam khwb cia hlau, tsawg chromium cam khwb cia hlau, npib tsib xee nyuaj cam khwb cia hlau thiab lwm yam ntau yam;
(3) Cov ntaub ntawv uas tsis yog xim hlau hnav-resistant series: xws li polymeric ceramic composite cov ntaub ntawv, silicon carbide (SiC), silicon nitride (Si3N4), toughened zirconia (Y2O3+ZrO2), toughened aluminium oxide (Al2O3 / ZrO2) ), thiab lwm yam.
(4) Tam sim no, hnav-tiv taus cov ntaub ntawv feem ntau suav nrog cov hauv qab no: hnav-tiv taus pob, hnav-tiv taus steel phaj, hnav-tiv taus electrode, hnav-resistant ceramics, hnav-resistant pem teb, hnav-resistant roj hmab, hnav-resistant pipeline, hnav-resistant bearing, hnav-resistant vuam khoom, hnav-resistant casting, casting pob zeb, polymer, composite hnav-resistant cov ntaub ntawv thiab lwm yam hnav-resistant cov ntaub ntawv.
2, kev siv cov khoom hnav-resistant
(1) High manganese hlau
High manganese steel yog tus cwj pwm los ntawm siab manganese (10%-14}%), siab carbon (0.9%-1.4%), txhawm rau txhim kho nws cov kev ua tau zoo, feem ntau ntxiv cov ntsiab lus alloying (nickel, chromium, molybdenum, thiab lwm yam), siab hardness. Vim muaj cov yam ntxwv tshwj xeeb ntawm cov hlau manganese siab, nws tau siv dav hauv kev ua haujlwm nrog kev cuam tshuam loj thiab hnav hnyav, xws li cov phaj hauv ob sab phlu, lub puab tsaig phaj, sib tsoo pob ntawm ntau lub tshuab gravel, thoob cov hniav ntawm excavators, thiab khiav. phaj ntawm lub tank loj. Mill phab ntsa roller, thiab lwm yam.
(2) Tsawg hnav-resistant alloy steel
Tsawg hnav-tiv taus alloy steel yog paub txog nws lub zog siab thiab toughness. Nws lub zog thiab hardness yog siab dua li cov hnav-resistant manganese steel thiab tuaj yeem hloov manganese hlau hauv cov khoom tsis muaj kev cuam tshuam. Nws cov plasticity thiab toughness yog siab dua li cov hnav-resistant cam khwb cia hlau, thiab nws cov kev pab cuam lub neej yog siab dua li ntawm hnav-resistant cam khwb cia hlau nyob rau hauv tej yam tej yam kev mob rau load hnav, uas yog dav siv nyob rau hauv kev ua liaj ua teb thiab mining machinery. W (C) (0.2%-0.35%) ntau cov khoom siv qis-alloy steel, tom qab dej quenching thiab tempering kho, siab hardness, zoo hnav tsis kam, nrog zoo zog thiab toughness, tsis yooj yim rau deformation thiab tawg nyob rau hauv kev siv, dav siv nyob rau hauv excavator, loader thiab tsheb laij teb thoob cov hniav, khiav phaj, me me thiab nruab nrab lub puab tsaig phaj, phaj rauj, rauj taub hau, pob zeb hauv ob sab phlu phaj thiab hais txog.
