Thaum lub fais fab laser ceev yog li 103-105 W / cm2. Laser nto tawv ntawm cov ntaub ntawv xws li cam khwb cia hlau, nruab nrab carbon hlau thiab txawm tias qis carbon hlau tuaj yeem ua tiav. Qhov tob ntawm quenching txheej yog feem ntau 0.7 rau 1.1 hli, thiab lub hardness ntawm quenching txheej yog kwv yees li 20% siab tshaj li ntawm cov pa quenching. Laser quenching deformation yog qhov me me. Nws tuaj yeem daws cov teeb meem ntawm saum npoo tawv tawv ntxiv ntawm cov carbon hlau tsawg. Thaum lub sijhawm txheej txheem laser quenching, qhov ntau ntawm superheat thiab supercooling yuav ua rau lub txheej tawv tsis ruaj, qhov cuam tshuam tsis zoo yog qhov siab heev thiab cov compressive kev nyuaj siab yog tsim rau txheej txheej. Ntxiv mus, tus coj tsis kam, qaug zog ua hauj, corrosion kuj, oxidation tsis kam thiab cov zoo li ntawm lub workpiece tau zoo heev. Ntev lub neej ntawm workpiece.
Daim ntawv thov ntawm lub tshuab laser quenching hauv kev ua liaj ua teb tsheb feem ntau suav nrog sab hauv phab ntsa ntawm lub tog raj kheej liner ntawm kev ua liaj ua teb tsheb cav, crankshaft, camshaft, sab nraud valve thiab lub rooj sib tw. Ltalis Fiat siv HPL-10 laser los kho lub sab hauv phab ntsa ntawm lub cav lub tog raj kheej liner, uas txo kev siv roj thiab txuag nqi. Augsburg-Nürnberg Machinery Manufacturing Co., Ltd. tau tsim ib txoj kab hluav taws xob laser rau kev sib tw hauv xyoo 1984 kom tau txais cov hlau loj loj lub tog raj kheej. Cov txheej txheem ntawm quenching txoj siv tau hla lub vev xaib, muab kauv thiab sine nthwv hom, uas zoo heev txhim kho hnav tsis kam ntawm lub tog raj kheej liner: Changchun FAW ua cov haujlwm laser quenching kev kho mob ntawm CAl41 tsheb cav lub tog raj kheej liner, thiab kev hloov kho mais tau nce mus rau 20x100000km : Qingdao Zhongfa Laser Technology Co., Ltd. siv laser network tshuab ua cov txheej txheem saum npoo ntawm lub cav loj lub tog raj kheej, crankshafts, thiab lwm yam, thiab lub neej cia siab tau nce los ntawm 3-5 zaug.
