Kev kho cua sovyog ib qho tseem ceeb ntawm cov txheej txheem tseem ceeb hauv kev tsim cov txheej txheem forging, uas ua lub luag haujlwm txiav txim siab hauv lub neej tuag. Raws li cov kev cai tshwj xeebforging tshuab, kev kho cua sov thev naus laus zis yog tsim los ua kom lub zog (hardness) ntawm cov pwm ua kom zoo nrog lub zog, qhov tawv tawv ntawm lub cev pwm thiab pwm bore yog tsim nyog thiab sib xws, cov nplej zoo thiab sib xws, tsis muaj oxidation thiab decarburization, txo qhov seem ntawm kev ntxhov siab thiab deformation, uas tuaj yeem txhim kho lub neej thiab ruaj khov ntawm pwm. Kev siv thev naus laus zis kho cua sov tshiab tuaj yeem siv cov khoom siv muaj peev xwm thiab txhim kho lub neej pwm ntawm tus nqi me me. Piv txwv li, rau high-carbontxias forging tuag, txais yuav qis-kub quenching kom tau ntau lat Martensite tuaj yeem txhim kho toughness, txo pwm deformation thiab quenching tawg, thiab yog li txhim kho pwm lub neej. Kev kho cua sov lub tshuab nqus tsev muaj qhov zoo ntawm tsis muaj oxidation, decarburization, degassing, cov cua sov tsis sib xws thiab me me deformation, uas yog qhov zoo rau kev txhim kho lub neej ntawm cov neeg tuag.

Cov nyhuv ntawm kev kho deg ntawm kev ntxiv dag zog rau saum npoo ntawm pwm bore thiab ua rau lub neej ntawm pwm tsis yog tsuas yog zoo kawg nkaus, tab sis kuj yog tus nqi qis. Tau siv thiab muaj peev xwm siv cov pwm saum npoo ntawm qhov cuab lub zog ntawm bore nto kho txoj kev muaj deformation (stee peening, extrusion thiab dov, thiab lwm yam) ntxiv dag zog rau, nto theem transformation ntxiv dag zog rau, nto expansion ntxiv dag zog thiab ion implantation ntxiv dag zog rau lub cev. vapor deposition thiab deg kev hloov technologies xws li membrane technology xws li tshuaj vapor deposition, thiab electrochemical deposition (electroplating) technology thiab thermal spraying. txheej txheej.
