Kev kho cua sov

Annealing: Qhov no yog txheej txheem ntawm cua sov lub workpiece mus rau qhov kub thiab txias, tuav nws rau qee lub sijhawm, thiab maj mam txias nws. Annealing feem ntau yog siv los ua kev kho mob ua ntej rau quenching, txhawm rau txhim kho cov khoom siv kho tshuab thiab lub cev ntawm cov khoom, tshem tawm cov kev ntxhov siab sab hauv, thiab txhim kho plasticity thiab toughness.

Normalization: Zoo ib yam li annealing, normalization kuj heats lub workpiece mus rau ib tug haum kub thiab txias nws nyob rau hauv huab cua. Nws lub hom phiaj tseem ceeb yog ua kom cov nplej zom, tshem tawm cov carbide network, thiab qee zaum siv los ua kev kho cua sov zaum kawg rau qhov tsis tseem ceeb.

quenching: quenching yuav tsum tau cua sov lub workpiece mus rau ib tug tej yam kub thiab ces sai txias nws nyob rau hauv dej los yog lwm yam quenching xov xwm. Lub hom phiaj tseem ceeb ntawm cov txheej txheem no yog ua kom lub zog ntawm cov hlau, tab sis nws kuj ua rau cov khoom embrittlement.

Tempering: Tempering yog nqa tawm tom qab quenching, tuav lub sij hawm ntev ntawm qhov tsim nyog kub saum toj no chav tsev kub tab sis qis dua 710 ℃, thiab ces txias kom txo tau lub brittleness ntawm quenched steel qhov chaw thiab txhim kho cov khoom ntawm cov khoom.

Kev kho cua sov saum npoo: suav nrog cov nplaim hluav taws kub, induction cua sov, laser, electrolysis thiab lwm txoj hauv kev, lawv tsuas yog siv los hloov cov khoom ntawm lub cev thiab tshuaj lom neeg ntawm cov khoom los txhim kho hnav tsis kam, corrosion kuj thiab lwm yam khoom.

Kev kho cua sov: suav nrog cov txheej txheem xws li carburizing, nitriding, carbonitriding, sulfurizing, boronizing, thiab metalizing, uas tsim cov txheej txheem nrog cov khoom tshwj xeeb ntawm cov khoom siv tshuaj lom neeg.
