2. Cov Txheej Txheem Kho Kub Hauv Kev Tsim Khoom Siv Iav

Kev kho cua sov yog ib qho txheej txheem tseem ceeb hauv kev tsim cov iav uas txhim kho qhov nyuaj, lub zog, thiab kev tiv thaiv kev hnav. Kev kho cua sov sib txawv raug siv nyob ntawm cov khoom siv thiab cov kev xav tau ntawm daim ntawv thov, Carburizin Induction Hardening Flame Hardening Nitriding Quenching thiab lwm yam.

2.1 Carburizing (Kev Ua Kom Lub Rooj Sib Tw Ruaj Khoov)

Kev ua kom lub zog sib zog (carburizing) yog kev ntxiv cov pa roj carbon rau saum npoo ntawm cov iav hlau uas tsis muaj carbon ntau. Tom qab ua kom lub zog sib zog (carburizing), cov iav raug tua kom ua ib txheej tawv sab nraud thaum tseem ua kom lub plawv tawv.

• Txheej Txheem: Lub iav raug cua sov rau hauv ib puag ncig uas muaj cov pa roj carbon ntau, ua raws li kev quenching.
• Cov txiaj ntsig: Qhov nyuaj ntawm qhov chaw nrog lub zog zoo heev.
• Cov ntawv thov: Cov iav tsheb, cov tshuab kev lag luam, cov khoom siv tsuas.

2.2 Kev ua kom nitriding

Nitriding ua rau nitrogen nkag mus rau saum npoo ntawm cov hlau alloy, tsim kom muaj ib txheej tawv, tiv taus hnav yam tsis tas yuav quenching.

• Txheej Txheem: Lub iav raug cua sov hauv huab cua nplua nuj nitrogen ntawm qhov kub qis.
• Cov txiaj ntsig: Tsis muaj kev cuam tshuam thaum lub sijhawm ua haujlwm, ua rau nws zoo tagnrho rau cov iav precision.
• Cov ntawv thov: Cov iav aerospace, cov khoom siv tsheb ua haujlwm siab, thiab cov tshuab precision.

2.3 Kev Kho Kom Ruaj Khov

Induction hardening yog kev kho cua sov hauv zos uas cov cheeb tsam tshwj xeeb ntawm cov iav tau cua sov sai sai siv cov kauj induction thiab tom qab ntawd quenched.

• Txheej Txheem: Cov teb hluav taws xob ntau zaus ua rau qhov chaw iav sov, ua raws li kev txias sai.
• Cov txiaj ntsig: Muab kev tawv qhov twg xav tau thaum tseem khaws cov tub ntxhais lub zog.
• Cov ntawv thov: Cov iav loj siv rau hauv cov tshuab hnyav thiab cov khoom siv mining.

2.4 Kev Ua Kub

Tempering yog ua tom qab quenching kom txo qhov brittleness ntawm cov iav hardened thiab txo cov kev ntxhov siab sab hauv.

• Txheej Txheem: Cov iav raug rov ua kom sov mus rau qhov kub nruab nrab thiab tom qab ntawd txias qeeb qeeb.
• Cov txiaj ntsig: Txhim kho qhov tawv thiab txo qhov muaj feem yuav tawg.
• Cov ntawv thov: Cov iav uas xav tau kev sib npaug ntawm lub zog thiab ductility.

2.5 Kev Txhaj Tshuaj Peening

Kev txhaj tshuaj peening yog ib qho txheej txheem kho qhov chaw uas ua rau lub zog qaug zog ntawm cov iav. Hauv cov txheej txheem no, cov hlaws me me raug tsoo rau ntawm qhov chaw ntawm cov iav kom tsim cov kev ntxhov siab compressive.

• Txheej Txheem: Cov hlaws dai lossis cov hlau txhaj tshuaj raug tua ntawm qhov ceev ceev rau ntawm qhov chaw iav.
