1. Core Testing Pain Points of Heat Treatment & Pwm Manufacturing Rhiav
Pwm, iav thiab nws pib qhov chaw kho cua sov cov chaw ua haujlwm nyob rau saum npoo ntawm cov txheej txheem xws li carburizing, nitriding thiab chrome plating los txhawb kev hnav tsis kam, tab sis cov cuab yeej siv tshuaj ntsuam hardness tsis tuaj yeem ua tiav cov txheej txheem kev soj ntsuam qhov tob, ua rau peb qhov kev puas tsuaj loj thiab kev soj ntsuam kev pheej hmoo.
Ua ntej, macro Rockwell lossis Brinell testers siv cov kev ntsuas hnyav uas nkag mus rau txheej txheej nyias, ntsuas cov txheej txheem tawv tawv tsis yog txheej txheej tawv, ua rau kev txiav txim siab tsis zoo ntawm cov txheej txheem quenching. Ntau cov tuam txhab lag luam tsis pom qhov tsis txaus carburizing qhov tob ua ntej xa khoom loj, ua rau cov neeg siv khoom txawv teb chaws rov qab los thiab cov nqi them hnyav. Qhov thib ob, phau ntawv kho qhov muag analog testers vam khom rau tus neeg teb xov tooj pom kev txiav txim siab me me indentation diagonals; Kev ntsuas qhov sib txawv tuaj yeem ncav cuag 5%-8% vim tib neeg qhov muag tsis pom kev sib txawv, tsim cov ntaub ntawv tsis sib xws ntawm cov ntaub ntawv tsis sib xws los ntawm European thiab Asmeskas pib OEM auditors. Thib peb, cov ntaub ntawv uas tau muab faib ua cov ntaub ntawv tsis tuaj yeem ua kom tsis tu ncua hardness gradient curves ntawm nto mus rau cov khoom tseem ceeb. Cov neeg soj ntsuam yuav tsum tau ua tiav txheej -ib-txheej HV faib kab kos los txheeb xyuas cov kev kho cua sov kom ruaj khov, thaum cov khoom siv analog tsis siv cov ntaub ntawv tsis siv neeg ua haujlwm.
Export-cov neeg muag khoom kho cua sov qhia tau hais tias cov ntaub ntawv tsis tiav txheej hardness traceability yog qhov laj thawj tseem ceeb rau TÜV thiab SGS kev tshuaj xyuas tsis yog-kev sib raug zoo, ncaj qha txiav ntev- lub sij hawm txiav txim siab ntau txoj hauv kev.
2. Cov Kev Ntsuas Tshwj Xeeb Microhardness Rau Nto Strengthened Workpieces
Cov tsis tshua muaj -load microhardness cov cuab yeej txhawb nqa ultra- lub teeb ntsuas lub teeb xws li 10gf txog 1000gf, zoo tagnrho rau kev sim txheej thickness ntawm 1μm mus rau 200μm yam tsis tau tho lub hauv paus hlau substrate. Nruab nrog 400 × siab- txhais lub hom phiaj kho qhov muag thiab nws pib- tsom lub koob yees duab digital, lub kaw lus cia li ntes cov pob zeb diamond indentations thiab suav cov kab pheeb suab ntev nrog qhov tseeb txog 0.1μm, tshem tawm tib neeg kev nyeem ntawv yuam kev. Cov tsim-hauv metallurgical tsom xam software npaj ntau- cov ntaub ntawv ntsuas cov ntsiab lus kom tso tawm qhov kev xav tau hardness gradient curves, qhia meej meej cov txiaj ntsig carburizing qhov tob thiab kev hloov pauv ntawm qhov nyuaj.
Ntiaj teb no pwm thiab iav kho cua sov labs txais yuavmicro vickers hardness testerkom standardize tag nrho nto txheej soj ntsuam workflows. Cov kws kho mob tsuas yog yuav tsum tau mount polished ntoo khaub lig-section qauv ntawm theem XY; lub tshuab cia li ua tiav ntau- taw tes matrix kuaj los ntawm qhov chaw ua haujlwm sab hauv, txiav ib zaug - qauv ntsuas lub sijhawm los ntawm 10 feeb mus rau tsawg dua 2 feeb. Tag nrho cov txiaj ntsig kev sim khaws cov txheej tuab, HV qhov tseem ceeb thiab cov duab indentation ua ke, ua cov ntaub ntawv tamper-cov ntaub ntawv pov thawj cov ntaub ntawv ua tau raws li ASTM E384 thiab ISO 6507 tus qauv.
Qhov kaw - voj voog hluav taws xob tswj qhov system tswj cov khoom tso tawm ruaj khov nrog ± 0.3% yuam kev, ua kom cov ntaub ntawv rov ua dua rau tib tus qauv hauv cov neeg ua haujlwm sib txawv thiab lub sijhawm, tshem tawm kev tsis sib haum xeeb txog kev kho cua sov cov qauv ntawm cov neeg muag khoom thiab cov neeg yuav khoom hauv qab.
3. Cov Neeg Esxias Sab Qab Teb Pwm Hoobkas Daim Ntawv Thov & Cov Khoom Siv Thib Ob Kev xa tawm tus nqi
Ib tug Nyab Laj txhaj tshuaj pwm kub kho lub Hoobkas muab German yas molding hom hloov kho cov cuab yeej ntsuas analog xyoo tas los los ntawm kev qhia cov cuab yeej digital microhardness. Tsis pub dhau rau lub hlis ntawm kev ua haujlwm ruaj khov, kev txiav txim siab ntawm nitriding txheej qhov tob poob los ntawm 76%, thiab batch rejection los ntawm unqualified nto hardness yog kiag li tshem tawm. Cov ntawv ceeb toom tsis tu ncua hardness gradient tau pab lub Hoobkas dhau ob qhov kev tshuaj xyuas txhua xyoo sib law liag yam tsis muaj kev tshuaj xyuas ntxiv -.
Nrog kev nthuav dav siab -hardness iav ntau lawm xaj, lub Hoobkas tau yuav ib txheej thib ob ntawm micro vickers hardness tester rau kev kho cua sov tshiab QC lab. Ob lub cuab yeej sib koom ua ke cov ntaub ntawv xa tawm cov qauv thiab preloaded kho cua sov parameter cov tsev qiv ntawv; QC cov kws tshaj lij ua haujlwm tsis pub dhau 30 feeb yam tsis muaj kev cob qhia kev tshaj lij ntawm cov tshuab sib txawv.
Rau export tshav kub kho factories tsom rau nto carburizing, nitriding thiab electroplating txheej txheem, tsawg-load siab-precision microhardness kuaj cov cuab yeej daws cov tseem ceeb txwv ntawm macro testers ntawm nyias txheej, raws li nruj thoob ntiaj teb kev soj ntsuam traceability yuav tsum, thiab txo cov khoom raw thiab cov khoom pov tseg uas tshwm sim los ntawm misjudged kub kho zoo.
FAQ
Q1: Cov ntsuas no puas tuaj yeem ntsuas qhov hardness ntawm ultra-thin chrome plating thinner dua 5μm?
A1: Yam tsawg kawg nkaus 10gf micro loads paub qhov chaw- tsuas yog indentation yam tsis tau nkag mus rau cov hlau substrate, raug nyeem plating HV qhov tseem ceeb.
Q2: Puas yog qhov tsim ua - hauv software tsim cov ntaub ntawv qhov tob gradient kab kos rau thib peb - tog neeg soj ntsuam xa?
A1: Ua ntej- teeb tsa daim ntawv qhia cov qauv tso tawm qhov chaw- mus rau -core hardness distribution curves, tag nrho lees paub los ntawm SGS, TÜV thiab thoob ntiaj teb automotive OEM auditors.
