1. ISO txheem System Offramework: tus qauv yam tsawg kawg nkaus rau cov khoom siv hluav taws xob
ISO / TC 261 thiab ASTM F42 ua haujlwm ua ke los tsim cov qauv kev tsim khoom. Qhov system no npog txhua yam ntawm cov ntaub ntawv thiab cov hau kev los tswj kom zoo rau kev ua cov khoom siv zog. Thaum nws los txog rau cov yam ntxwv ntawm cov khoom siv zog zog, peb yuav tsum tau them sai sai rau cov qauv hauv qab no:
Cov lus qhia tshwj xeeb rau cov khoom siv
ISO / ASTM 52901 {{- 16 "Kev ua tiav cov khoom siv yuav tsum tau muab cov ntaub ntawv ntxiv rau lawv cov txheej txheem siv los ua cua sov kho lawv. Nickel {{6- Raws N07718), piv txwv li tus qauv F3055-148% kom tiv thaiv kom tsis txhob muaj qhov kub siab. Titanium alloy (Ti6al4V) yuav tsum ua raws F2924-14 tus qauv, nrog cov ntsiab lus pa ntawm tsis muaj ntau tshaj 0.13% los xyuas kom huv si lub neej.
Kev tswj ntawm cov txheej txheem
Cov "kev tshwj xeeb rau cov hlau hmoov txaj melted txheej txheem" (is / {{[{{1} {{1} ± 10 μ m) nyob rau hauv lub sijhawm tiag tiag. Piv txwv li, ge tau tuaj yeem tswj hwm qhov loj ntawm cov nplej hauv cov roj turbine tuaj rau hauv 5 m ua tsaug rau cov qauv no. Qhov no tau txhim kho qhov siab-kub lub neej ntawm cov ntu los ntawm 30%.
Kuaj xyuas kom zoo
ISO / ASTM 52902 {{- 19 "kev ntsuas ntawm cov khoom luam ntawv" hais tias xoo hluav taws xob ct scanning yuav tsum tau nrhiav kom pom kev tsis zoo sab hauv. Lub paj hlwb yuav tsum tsawg dua 0.5%, thiab ntau qhov loj tshaj plaws loj tshaj plaws yuav tsum tsis pub ntau tshaj 50 μm. Raws li tus qauv no, siemens lub zog tau txiav tus nqi ntawm kev tawg tsis xws nyob hauv cov roj ntau lawm hauv 2.3% rau 0.07%.
2. Txoj kev ua raws cai rau kev ua cov khoom siv hluav taws xob
1. Tsim theem: Topology Optimization raws li ISO 52911
Thaum tsim cov cuab yeej siv zog, ob qho tib si sib xyaw ua haujlwm thiab tsim kev lag luam tsim nyog yuav tsum tau coj mus rau hauv tus account. ISO 52911-1 "Cov Lus Qhia Tsim Kev Tsim Laser Melting ntawm cov ntaub hlau hlau" hais tias
Kev ntxhov siab ntxhov siab: Peb siv cov hom phiaj lossis Abaqus kom ua cov khoom siv cua nab kuab kom paub tseeb tias cov khoom siv uas muaj sijhawm ntau dua 30% ntawm cov khoom siv tau tawm los lub zog.
Cov Qauv Txhawb: Ua raws ISO 52911 - 2 "qauv kev txhawb nqa zoo li nws tuaj yeem yog txo qis txoj hauv kev deformation tom qab kev kho mob. Piv txwv li, thaum ua lub siab siab lub nkoj rau nuclear reactors, ib tsob ntoo zoo li txhawb nqa cov qauv lever los ntawm 42%.
Cov hom ntaub ntawv: kom paub tseeb tias txhua tus ntawm geometric tus yeeb yam (zoo li 0.2mm yuag phab ntsa) thiab cov txheej txheem laser) thiab cov qauv amf) thiab cov qauv siv laser)
2. Kev luam ntawv: ISO 52900 drives kaw - lub voj tswj ntawm cov txheej txheem
Txhawm rau ua cov cuab yeej siv zog, tsib {- © qib qib kev tswj kom haum yuav tsum muab tso rau hauv qhov chaw:
Calibration ntawm cov khoom siv: "Laser Focussing Qhov Tseeb Qhov Tseeb" GB / T 39445-2020 μ ± 2 ± 2 ± 2 ± 2 ± 2) Yuav tsum tau kuaj xyuas ua ntej pib hnub.
Kev tswj cov ib puag ncig: kom muaj nickel - Raws li cov ntsuas kub ntawm 50 ppm lossis tsawg dua thiab tsawg dua.
Saib rau online: Siv lub pyrometer infrared infrared tus pas ntsuas kub los ua kom lub qhov muag ntawm qhov kub ntawm Molten pas dej nyob rau hauv tiag tiag lub sijhawm (nrog qhov tsis raug ntawm ± 5 degree). Siv cov txheej txheem kev kawm siv tshuab kom kwv yees thaum tsis xws luag yuav tawm.
Txhawm rau kom tsis txhob hmoov agglomeration thiab tsis zoo interlayer tsev, ua kom pom kev faib tawm (d {{} μg) kuaj raws li ISO / ASTM 52907-19.
Kev siv cov txheej txheem: ua ntej luam tawm txhua pob, nws yog ib qho tseem ceeb rau kev kuaj cov tshuaj Tensile (ASTM ET8) thiab kev ua kom paub meej tias qhov kev ua tau zoo ua tiav cov kev cai.
3. Cov theem tom qab kev ua: ISO 52921 kev txhim kho kev ua haujlwm txhim kho
Feem ntau, cov khoom siv hluav taws xob feem yuav tsum mus dhau ob peb qho post - txheej txheem txheej txheem:
ISO / ASTM 53301-18 hais tias Inconel 718 xav tau kho tshav kub thaum 1150℃thiab hnub nyoog ntawm 720℃kom ncav cuag txoj kev tawv ntawm HRC 42-45.
Txhawm rau ua kom cov nplaim hluav taws xob ntxiv rau corrosion, nws yog tua Peened (Almen Lub Zog 0.016A-0.022a) lossis Ultrasonicness 5-10 μm). Qhov no ua tau raws li NACE MR0175 txheem.
Tsis - phasuctive kev kuaj: Ultrasonic phased kev xeem yuav tsum tau ua raws li {6db thiab ib lub tiaj-hauv qab lub cheeb ntawm tsawg dua 0.8mm.
