Laser Hardening txheej txheem: Theem Transformation, Melting thiab Shock Hardening piav qhia

Laser hardening yog ib qho ntawm cov kev siv tshiab ntawm laser tshuab hauv kev tsim khoom. Nws siv lub teeb laser los ua kom sov saum npoo ntawm cov hlau ua haujlwm hauv zos thiab nrawm, kom lub ntsej muag hardness, hnav tsis kam thiab corrosion kuj tau txhim kho mus rau qhov sib txawv thiab kev pab cuam lub neej ntev. Lub hauv paus theoretical yog kev sib cuam tshuam ntawm cov hluav taws xob laser thiab cov khoom siv - thiab cov txiaj ntsig tshwj xeeb yog nyob ntawm peb yam: lub zog laser, lub zog ceev, thiab lub sijhawm raug.

Txhawm rau ua tiav cov ntsiab lus ntawm metallurgical mechanism thiab nws cov precision, saib peb phau ntawv qhialaser nto hardening piav qhia.

Nyob ntawm seb lub zog laser xa thiab nqus tau li cas, laser hardening poob rau hauv peb cov txheej txheem sib txawv.

1. Theem Transformation Hardening

Lub laser scans lub workpiece nto thiab heats nws sai tshaj qhov kub tseem ceeb. Thaum lub beam txav mus, qhov txias substrate ua cua sov tam sim ntawd, quenching cheeb tsam thiab ua rau martensite los yog bainite transformation. Qhov no yog cov txheej txheem siv dav tshaj plaws, xa cov txheej txheem nruj tswj hwm tsis muaj kev hloov pauv ntawm chemistry.

2. Melting & Solidification Hardening

Thaum lub zog muaj zog ntau dua, txheej txheej saum npoo melts thiab rov ua dua -solidifies sai heev. Qhov ua tau zoo, homogeneous qauv muab kev txhim kho hardness thiab txhim kho corrosion kuj piv rau cov khoom- lub xeev transformation ib leeg.

3. Shock Hardening

Qhov khaus, luv luv laser mem tes tsim ib qho kev poob siab uas ua haujlwm- tawv tawv los ntawm cov yas deformation. Cov txheej txheem no qhia txog compressive residual kev nyuaj siab, uas yog tshwj xeeb tshaj yog muaj txiaj ntsig rau kev txhim kho qaug zog.

Peb cov txheej txheem tsis yog sib koom ua ke - lawv txawv tsuas yog hauv laser lub zog thiab lub zog ntom ntom, thiab tuaj yeem hloov kho kom haum rau cov khoom siv thiab qhov xav tau hardening qhov tob.

Laser hardening yog tshwj xeeb tshaj yog zoo nyob rau hauv xya scenarios uas cov pa kev kho cua sov tawm tsam:

1. Loj workpieces uas nyuaj rau haum rau hauv lub qhov cub kho cua sov.
2. Cov khoom uas yuav tsum tau kho tsuas yog nyob rau thaj chaw hauv cheeb tsam xws li grooves, qhov thiab npoo.
3. Cov khoom uas nyuaj rau kev ua haujlwm nrog kev kho cua sov.
4. Precision qhov chaw nrog nruj txwv ntawm kev kho cua sov distortion.
5. Nto hardening ntawm cam khwb cia hlau workpieces.
6. Cov khoom ua rau tawg raws li kev kho cua sov.
7. Cov khoom uas tsis ncav cuag hardness yuav tsum tau los ntawm cov pa kev kho cua sov.

Raws li ceev ceev, tsis yog - txheej txheem sib cuag, laser hardening yuav tsum tsis muaj quenchant sab nraud, ua kom tsawg workpiece distortion thiab lub voj voog ceev ceev. Piv nrog cov nplaim taws tawv thiab carburizing, nws siv siab - laser cua sov uas yuav tsum tau muaj tsawg dua cov kauj ruam thiab khiav ceev dua. Cov txheej txheej tawv tawv yog sib xws, thiab qhov tawv tawv feem ntau yog 15-20% siab dua li cov pa tawv tawv. Cov cua kub qhov tob thiab trajectory yog yooj yim los tswj, yooj yim kho, thiab amenable heev rau automation.

Laser nto hardening yog dav siv nyob rau hauv kev lag luam xws li pwm, mechanical manufacturing, roj av, tshuaj lom neeg kev lag luam, lub teeb kev lag luam, cuab yeej kho vajtse, thiab automotive qhov chaw vim nws zoo heev tshav kub kev kho mob kev kawm. Ntawm lawv, cov hlau alloys yog cov khoom siv dav tshaj plaws hauv kev lag luam, nrog cov txheej txheem microstructures uas tuaj yeem tswj tau los ntawm kev kho cua sov laser los hloov lawv cov khoom siv kho tshuab, lub cev, thiab tshuaj lom neeg thiab ua tiav kev ua haujlwm sib txawv. Tej workpieces muaj xws li pwm, iav, ncej, threads, qhia rails, lub tog raj kheej liners, cov khoom tseem ceeb tub rog, thiab lwm yam.

Laser hardening ua tiav qhov chaw ntxiv dag zog los ntawm peb lub tswv yim - theem hloov pauv, melting -solidification thiab poob siab - xaiv los ntawm tuning lub zog, lub zog ceev thiab lub sij hawm raug. Rau kev sib piv kom muaj nuj nqis ntawm cov txheej txheem tiv thaiv induction, nplaim taws thiab carburizing txoj kev, nyeem peb phau ntawv qhia ntawmqhov zoo ntawm laser nto hardening.
