Alloying

 

Txoj Cai: Lub microstructure ntawm steel yog hloov los ntawm kev ntxiv alloying ntsiab rau hlau, yog li ua rau nws hardness. Piv txwv li, thaum ntxiv chromium (Cr) cov khoom, chromium tuaj yeem tsim cov carbide nrog carbon hauv hlau, xws li thiab . Cov carbides muaj cov yam ntxwv ntawm qhov siab hardness thiab siab melting point, thiab yog dispersed nyob rau hauv cov hlau matrix, uas muaj peev xwm cuam tshuam lub zog ntawm dislocations thiab nce hardness ntawm cov hlau. Feem ntau hais lus, qhov siab dua cov ntsiab lus ntawm chromium, ntau carbides tsim, thiab qhov pom tseeb qhov nce hauv steel hardness. Thaum cov ntsiab lus chromium nce mus txog qee qhov kev faib ua feem (piv txwv li, cov ntsiab lus chromium hauv stainless hlau yog li 13% - 30%), qhov nyuaj ntawm cov hlau yuav nce ntxiv.

 

 

Kev kho cua sov - quenching

 

Txoj Cai: quenching yog cua sov - txheej txheem kev kho mob uas cov hlau yog rhuab saum toj no qhov tseem ceeb kub, tuav rau ib lub sij hawm ntawm lub sij hawm, thiab ces txias sai heev. Thaum lub sij hawm cua sov txheej txheem, lub microstructure ntawm steel hloov thiab austenite yog tsim. Thaum lub sijhawm txias sai, austenite tsis muaj sijhawm los hloov mus rau cov ntaub so ntswg xws li pearlite, tab sis hloov mus rau martensite. Martensite yog ib qho kev daws teeb meem supersaturated, uas muaj cov yam ntxwv ntawm hardness siab thiab siab zog. Piv txwv li, rau nruab nrab - carbon steel, lub hardness tuaj yeem nce ntxiv tom qab quenching. Qhov no yog vim qhov tsim ntawm martensite ua rau muaj ntau qhov sib txawv ntawm cov lattice nyob rau hauv cov hlau, thiab kev txav ntawm dislocations yog heev txwv, yog li ua rau lub hardness.

 

Cov kev ceev faj: Tus nqi cua txias thaum lub sij hawm quenching yog ib qho tseem ceeb heev. Yog tias qhov txias txias qeeb dhau, austenite tuaj yeem hloov pauv mus rau hauv cov ntaub so ntswg xws li pearlite, uas ua rau tsis muaj zog txaus; Txawm li cas los xij, yog tias qhov cua txias nrawm dhau, nws tuaj yeem ua rau deformation lossis tawg ntawm cov hlau. Nyob rau tib lub sijhawm, cov hlau sib txawv muaj qhov sib txawv ntawm qhov tseem ceeb, thiab qhov kub thiab txias yuav tsum tau txiav txim siab raws li qhov muaj pes tsawg leeg ntawm cov hlau. Feem ntau, cov txheej txheem quenching tsim nyog yog txiav txim siab los ntawm kev sim lossis xa mus rau cov ntaub ntawv kho cua sov uas cuam tshuam.

 

 

Daim ntawv thov Scenario: Carburizing kev kho mob yog dav siv nyob rau hauv lub tshav pob ntawm mechanical manufacturing, tshwj xeeb tshaj yog rau qhov chaw uas yuav tsum tau siab rau hnav kuj. Dhau li ntawm cov iav, nws kuj suav nrog cov ncej - zoo li qhov chaw, piston pins, thiab lwm yam. Thaum lub sijhawm ua haujlwm ntawm cov khoom no, qhov saum npoo yuav tsum muaj kev sib txhuam thiab hnav. Los ntawm kev kho carburizing, qhov tawv tawv tuaj yeem ua kom zoo dua thiab kev pabcuam lub neej tuaj yeem txuas ntxiv.

Kev kho deg - Nitriding

 

Txoj Cai: Nitriding yog txheej txheem uas nquag nitrogen atoms tso cai rau nkag mus rau hauv cov hlau ntawm qhov kub thiab txias los tsim ib txheej nitrided. Cov txheej nitrided muaj siab hardness, siab hnav tsis kam thiab zoo corrosion kuj. Sib txawv ntawm carburizing, qhov chaw tom qab kev kho nitriding muaj tsawg deformation. Thaum lub sij hawm cov txheej txheem nitriding, nitrogen atoms tsim nitrides nrog alloying ntsiab nyob rau hauv cov hlau (xws li txhuas, chromium, vanadium, thiab lwm yam), xws li , , , thiab lwm yam. Cov nitrides yog dispersed rau saum npoo ntawm cov hlau, ua rau lub hardness ntawm nto. . Piv txwv li, rau qee qhov siab - precision pwm thiab cov khoom siv tshuab, kev kho nitriding tuaj yeem ua rau lawv qhov tawv tawv ncav cuag HV900 - 1200 (Vickers hardness).

 

Qhov zoo: Qhov kub ntawm nitriding kev kho mob kuj qis (feem ntau ntawm 500 - 600 degree ). Piv nrog rau carburizing, nws yuav tsis ua rau loj deformation ntawm cov hlau, thiab nws yog ntau haum rau qhov chaw nrog complex duab thiab siab yuav tsum tau rau qhov loj qhov tseeb. Ntxiv mus, cov txheej nitrided muaj kev tiv thaiv corrosion zoo thiab tuaj yeem txhim kho lub neej kev pab cuam ntawm cov khoom hauv qhov chaw hnyav.
