Nto hardness thiab kev sib txuam ntawmNcej Kev Nco Ntsoovyog cov khoom tseem ceeb ntawm kev xav tau thiab tshuaj xyuas kev kuaj xyuas. Lub cev tawv ntawm lub cev qhia pom cov hnav tsis kam, thiab lwm yam, lub resilience ntug dej D hardness D hardness tus nqi HSD yog siv los qhia.
Lub hardness xav tau ntawm cov ncej forgings feem ntau yog raws li qhov nyuaj ntawm cov menyuam ua haujlwm lossis ob qho tib si yuav tsum khaws kev sib raug zoo. Raws li cov kev tshawb fawb ntawm kev sib cuag cov me nyuam qaug zog, lub hardness ntawm cov kev pab txhawb nqa yuav tsum yog 10-25 hs units qis dua li ntawm kev ua kom qaug zog hauv thaj chaw tiv toj. TawvNcej Kev Nco NtsoovMuaj cov coj qis kev coj tawm tsam thiab muaj feem cuam "tev duab" tshwm sim txheej ntawm cov npoo av tsim cov khoom tawg yooj yim thiab tom qab ntawd ua rau cov xim av me; Thaum Hardness yog dhau lawm, txoj hmoo ntawm brittle spalling nce. Raws li cov pob txha lov tawv muaj nqi ntawm hardened txheej yog tsawg, ib zaug tshwm sim, nws yuav kis tau sai, uas ua rau muaj mob hnyav, ua rau muaj mob hnyav. Siab dua ua tau yuav ua rau muaj kev phem kev puas tsuaj thiab hnav ceevNcej Kev Nco Ntsoovthiab luv luv lub sijhawm sib tsoo ntawmNcej Kev Nco Ntsoov.

Nyob rau hauv xyoo tsis ntev los no, lub hardness ntawmNcej Kev Nco Ntsoovntawm txias thiab kub dov zeb tau feem ntau tau txhim kho, centrifugal composite thiab tau txhawb nqa qib kub thiab tau txhawb nqa cov tshuab hluav taws xob siab thiab siab tshaj plaws txwv tsis pub cov khoom txias Hlau qaws. Lub hardness theem ntawmNcej Kev Nco Ntsoovtau mus txog 70-83. Qhov tam sim no cov ntaub ntawv forgings thiab tsim cov cuab yeej siv hluav taws xob tuaj yeem ntsib lub hardness forgings. Nyob rau tib lub sijhawm, kev siv lub hardness siab coing forging thev naus laus zis kuj tau sau ntau yam kev paub.
Tus superLoj Ncej Kev Nco NtsoovNtawm phaj zeb loj loj nyob rau hauv loj thiab hnyav nyob rau hauv ceeb thawj, thiab cov dov nrawm yog ntau me dua uas ntawm sawb zeb. Yog li no, hnav tsis kam thiab cov kev xav tau nyuaj kuj tseem txo qis dua.
