Taw qhia
Puas yog chrome nyuaj dua hlau? Qhov no yog ib lo lus nug uas tau intrigued ntau tus neeg rau lub sij hawm ntev. Lo lus teb rau lo lus nug no tsis yog ncaj nraim, vim nws nyob ntawm ntau yam. Hauv tsab xov xwm no, peb yuav tshawb txog qhov sib txawv ntawm chrome thiab hlau thiab seb lawv qhov hardness yog li cas.
Chrome yog dab tsi?
Chrome yog cov hlau uas paub txog nws qhov ci ntsa iab thiab ua haujlwm rau corrosion. Cov hlau no yog ib daim ntawv ntawm lub caij chromium, uas yog ib qho nyuaj, silvery hlau uas feem ntau siv los tsim cov hlau. Chrome muaj kev tiv thaiv corrosion ntau dua piv rau cov hlau, uas ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv, suav nrog cov khoom siv tsheb, khoom siv hauv tsev, thiab chav dej.
Steel yog dab tsi?
Hlau yog cov hlau alloy uas muaj hlau, carbon, thiab lwm yam xws li manganese, chromium, thiab npib tsib xee. Hlau yog dav siv nyob rau hauv kev tsim kho, tsheb thauj mus los, thiab ntau lwm yam lag luam vim nws lub zog, durability, thiab versatility. Muaj ntau ntau hom hlau, txhua tus muaj cov khoom tshwj xeeb thiab kev siv.
Yuav txiav txim siab li cas?
Lub hardness ntawm ib tug hlau yog nws tsis kam mus deformation, khawb, los yog indentation. Lub hardness ntawm ib tug hlau yog txiav txim los ntawm ob yam tseem ceeb: hom hlau thiab txoj kev nws tau ua tiav.
Muaj ntau txoj hauv kev siv los txiav txim siab qhov nyuaj ntawm cov hlau, suav nrog Brinell, Rockwell, thiab Vickers hardness tests. Cov kev ntsuam xyuas no suav nrog kev siv lub zog uas paub txog rau saum npoo ntawm cov hlau thiab ntsuas qhov tshwm sim indentation.
Chrome vs Steel
Thaum nws los txog rau hardness, chrome feem ntau nyuaj dua hlau. Chrome muaj qhov hardness ntsuas ntawm 9 ntawm Mohs nplai, thaum hlau ntog ntawm 4 thiab 8 ntawm qhov teev, nyob ntawm seb hom thiab kev ua haujlwm. Qhov no txhais tau hais tias chrome yog qhov tiv taus ntau dua rau khawb, indentation, thiab deformation dua li cov hlau.
Txawm li cas los xij, hardness tsis yog tib yam uas yuav tsum xav txog thaum sib piv chrome thiab hlau. Hlau feem ntau muaj zog thiab ruaj khov dua li chrome, uas txhais tau hais tias nws tuaj yeem tiv taus kev ntxhov siab ntau dua thiab tsis muaj kev tawg lossis deforming. Hlau kuj tseem tiv taus qhov cuam tshuam thiab lwm yam kev puas tsuaj.
Cov kev siv ntawm Chrome
Chrome feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum muaj kev tiv thaiv corrosion thiab qib siab ntawm ci ntsa iab. Qee qhov kev siv ntau ntawm chrome suav nrog:
- Automotive qhov chaw, xws li lub log, lub pob, thiab cov kav dej
- Cov khoom siv hauv chav ua noj, xws li faucets, tes tuav, thiab dab dej lim dej
- Cov khoom siv hauv chav dej, xws li lub taub hau da dej, phuam da dej, thiab xab npum dispenser
-Aerospace Cheebtsam, xws li tsaws iav thiab cav qhov chaw
- Cov cuab yeej suab paj nruag, xws li nruas teeb thiab cymbals
Kev siv hlau
Hlau yog dav siv nyob rau hauv ntau industries vim nws lub zog, durability, thiab versatility. Qee yam kev siv steel hlau muaj xws li:
- Cov khoom siv tsim kho, xws li kab teeb, kab, thiab cov khoom siv ntxiv
- Tsheb qhov chaw, xws li cov ncej, ncua kev kawm ntawv, thiab cav thaiv
- Machinery thiab khoom siv, xws li cav, iav, thiab bearings
- Cov cuab yeej thiab cutlery, xws li riam, saws, thiab rauj
- Kev kho mob cog thiab khoom siv, xws li orthopedic implants thiab cov cuab yeej phais
Xaus
Hauv kev xaus, ob qho tib si chrome thiab hlau muaj lawv cov khoom tshwj xeeb thiab kev siv. Thaum chrome feem ntau nyuaj thiab ntau dua corrosion-resistant dua hlau, steel kuj muaj zog thiab ruaj khov, ua rau nws haum rau ntau yam kev lag luam. Thaum xaiv ntawm chrome thiab hlau, nws yog ib qho tseem ceeb uas yuav tau xav txog lawv cov khoom tshwj xeeb thiab daim ntawv thov npaj los ua qhov kev xaiv.
