Plaub yam ntxwv ntawm riam khoom uas cuam tshuam rau nws kev ua tau zoo

Hauv kev xaiv cov riam zoo tshaj plaws koj yuav tsum tau them nyiaj tshwj xeeb rau hom hlau siv hauv cov hniav. Cov khoom siv raw zoo yog lub hauv paus ntawm cov riam zoo. Hardness, corrosion-resistance, hnav-tiv taus thiab ntug-retention, saum toj no yog plaub lub ntsiab yam ntxwv uas mus rau hauv kom muaj riam ntse.

Hardnesshais txog riam hniav ntom ntom. Nyob rau hauv lub tshuab riam hniav kev lag luam, hlau hardness yog tsuas yog ntsuas ntawm Rockwell C nplai. Feem ntau, qhov siab dua tus lej Rockwell C yog, qhov ntom ntom thiab yog li ntawd cov khoom siv nyuaj dua. Tab sis tsuas yog vim qee cov hlau muaj qhov siab Rockwell nplai tsis txhais hais tias cov khoom siv tau ruaj khov lossis tawv. Ntau cov hlau loj tau yooj yim erodes thiab sai sai poob lawv ntug.

Hnav-tiv tausyog lub peev xwm ntawm cov ntaub ntawv los tiv thaiv raug abraded los yog eroded los ntawm kev sib cuag nrog cov khoom ua hauj lwm, los yog sab nraud influences (av, grit, pob txha, thiab lwm yam) hnav tsis kam yog muab los ntawm ob lub hardness theem thiab chemistry ntawm riam hniav. Muaj 2 hom kev hnav kev puas tsuaj hauv riam, abrasive thiab nplaum.

Hnav cuam tshuam nrog kev yaig lossis kev sib hloov ntawm cov npoo yog hu ua abrasive hnav. Abrasive hnav tsis xav tau kev kub siab. Abrasive hnav kuaj yuav suav nrog xuab zeb, ntawv xuab zeb, lossis ntau yam slurries lossis hmoov.

Hnav los ntawm kev sib raug zoo ntawm ob qhov chaw du, xws li steel ntawm steel, carbide ntawm steel, thiab lwm yam, yog hu ua nplaum hnav. Adhesive hnav tuaj yeem cuam tshuam qhov tseeb tearing ntawm cov khoom ntawm cov ntsiab lus ntawm kev sib cuag siab vim kev sib txhuam.

Corrosion-tiv taushais txog lub peev xwm los tiv thaiv lub substrate los ntawm corrosion. Nws yog ib qho kev ntsuas ntawm riam hlau tsis kam mus tua nyob rau hauv high humidity, damp, los yog ntsev ib puag ncig. Corrosion kuj yog los ntawm chromium ua "passive film" ntawm chromium oxide uas tiv thaiv corrosion ntxiv. Lub ntsiab tseem ceeb uas cuam tshuam rau corrosion kuj yog cov ntsiab lus chromium ntawm cov hlau. Ntau chromium txhais tau hais tias cov zaj duab xis passive yog ua tiav ntawm cov hlau nto kom zoo dua tiv thaiv corrosion. Lwm yam uas cuam tshuam rau corrosion kuj yog cov ntsiab lus carbon ntawm cov hlau. Cov pa roj carbon thiab chromium hauv cov hlau nyhav ua rau tsim cov chromium carbides, thiab thaum chromium raug khi rau hauv carbides nws tsis muaj los tsim cov zaj duab xis passive los tiv thaiv corrosion.

Ntug-retentionhais txog ib tug hniav lub peev xwm los tuav ib tug ntse ntug. Qee cov hlau yuav plam lawv cov ntug tom qab siv tas li, thaum lwm tus tuaj yeem tuav lub kaum sab xis kom ntev ua ntej lawv yuav tsum tau ua kom zoo. Slicing ntug tuav tswj tau zoo heev los ntawm kev hnav tsis kam thiab nws feem ntau yog ntsuas los ntawm CATRA ntug kev ntsuas. Qhov kev sim no siv cov slicing ntawm 5 feem pua ​​​​silica-impregnated cardstock thiab yog li ntawd sim slicing ntug tuav. Ntug tuav yog feem ntau cuam tshuam inversely toughness (toughness yog hais txog qhov zoo ntawm riam hniav tiv taus yaig thiab puas ).

Koj yuav xaiv cov khoom uas muaj siab hardness thiab toughness los ua koj cov riam zoo tagnrho. Hmoov tsis zoo, qhov ntawd tsis tau. Lub cev muaj zog hais tias cov hlau nyuaj yuav ua rau nkig thiab puas yooj yim. Cov hlau Softer tuaj yeem dhau los ua qhov tawv zoo kawg li vim lawv nthuav tawm elasticity uas absorbs txawv teb chaws rog.

Nrhiav qhov sib npaug ntawm cov saum toj no plaub yam yog qhov peb cov neeg siv khoom nyob ntawm. Thov ua siab zoo nco ntsoov tias tsis muaj cov khoom siv zoo tshaj plaws, qhov peb yuav tsum ua yog xaiv qhov tsim nyog tshaj plaws raws li peb daim ntawv thov.

Tseem tsis paub tseeb tias cov khoom siv twg yog qhov zoo tshaj plaws rau koj daim ntawv thov? Tsis muaj teeb meem, peb tuaj yeem pab koj txiav txim siab!
