Cov ntaub ntawv twg yog cov hnav feem ntau hnav - tiv taus 3D luam tawm hlau qhov chaw?

Hauv kev lag luam lag luam, cov hnav tsis kam ntawm 3D -}}}}}} Cov luam tawm cov nyiaj txiag yog ncaj qha rau cov khoom siv lifespan, ua haujlwm zoo, thiab muaj kev nyab xeeb. Thaum ntsib nrog cov txheej txheem nyuaj lossis tus kheej cov cai yuav tsum tau, koj xaiv lub "vaj ntxwv ntawm cov khoom siv khoom siv? Cov kab lus no ntsuas cov xaiv qhov tseem ceeb ntawm peb kev xam pom: cov khoom siv, kev siv cov xwm txheej, thiab cov txheej txheem sib xws, thiab kev sib haum xeeb.

1. Tus tub ntxhais ntawm kev hnav tsis kam: cov khoom siv tau txiav txim siab txog qhov kev ua tau zoo sab saud

Ib hlau txoj kev tiv thaiv yog qhov tseem ceeb nws lub peev xwm los tiv thaiv kev hnav, uas yog ze ze rau nws lub hardness, kev nruj, microstructure, thiab tshuaj lom neeg ruaj khov. Hauv 3D luam ntawv, peb cov ntaub ntawv hauv qab no yog cov kev xaiv piav txog kev coj tawm tsam vim lawv cov txiaj ntsig zoo:

1. Cobalt - chromium alloys: "hnav {{} illSive Duo" ntawm cov ntawv thov kho mob thiab muaj kev lag luam

Cobalt - chromium alloys (CIP) muaj npe rau lawv lub zog siab, corrosion tsis kam, thiab biocompatibility. Lawv lub hardness tuaj yeem ncav cuag hrc 40 -}}} tshaj plaws ntawm cov hlau tsis muaj zog stainless. Hauv kev kho mob teb, 3D -} printing lub hauv caug thiab duav prosthes nthuav tawm cov khoom muaj zog ntawm tib neeg cov lus tsa suab thiab kev sib txhuam. Hauv kev siv cov ntawv thov, li qub thiab cov twj tsim los ntawm cov ntawv sau ua kom cov nqi tsis muaj dej uas muaj cov xuab zeb. Piv txwv li, cov tuam txhab roj siv cobalt-Chromium alloy luam cov khoom drilling cov khoom, ua tiav lub sijhawm peb zaug ntau dua li cov ntaub ntawv ib txwm muaj.

2. High {{{{{}} silicon alloys: ib qho "hnav {{{} {}}} kub ib puag ncig

Siab - tsov ntxhuav alloys, xws li alsi60, muaj ntau yam ntawm cov khoom sib xws ntawm kev sib faib, muaj ntau lub hardness ntawm matrix. Cov ntaub ntawv no ua tau zoo nyob rau hauv high- kub, siab siv nyob rau hauv dav hlau cav sib txuas thiab aerodynamic qhia cov khoom. Nws cov coj tsis kam qia los ntawm "cov nyhuv tawv me me" ntawm cov pob zeb ua kom zoo li cov me me los ua kom muaj kev sib cuag tshwj xeeb los tiv thaiv kev sib tsoo.

3. Cuab Yeej Steel: ib qho "hnav - tiv taus cov txiv neej tawv tawv" rau hnyav- duty {

Siv H13 {- Ua haujlwm tuag taus, piv txwv li, nrog lub hardness ntawm li {}} kub lub zog nrog kev nkees nkees ua hauj lwm. Hauv 3D luam ntawv, cuab yeej hlau, los ntawm kev ua kom zoo dua faib cov khoom tawg thiab kev kho cua sov} Ib lub tsheb tsim khoom siv 3D -}}} cov luam tawm pwm ua los ntawm H13 steel. Tom qab 100,000 txuas ntxiv tuag-cam khwb cia mus los mus los, cov kab noj hniav saum npoo du, nrog hnav tsawg dua 0.01mm.

Ii. Daim Ntawv Thov Kev yoog raws: Cov hnav Kuj Drives Cov Khoom Siv

Hnav kuj tsis yog ib qho metric; Nws yuav tsum muaj kev nkag siab zoo nyob rau hauv lub teeb ntawm kev ua haujlwm ib puag ncig:

Rau siab -}} kub fresh (xws li {}} {} chromium alloys yog nyiam. Cov ntaub ntawv no tswj hwm lawv lub hardness saum 800℃thiab haum rau cov khoom xws li cov cua tshuab tshuab hluav taws xob tshuab hluav taws xob tuaj thiab roj av tshuab txuas ntxiv.

Rau cov xov xwm corrosive ib puag ncig: titanium alloys (xws li Ti6al4V) yog qhov zoo rau cov khoom siv marine thiab cov khoom siv tshuaj lom neeg vim lawv lub zog tiv taus cov acids thiab alkalis. Cov yeeb yaj kiab oxide tsim ntawm lawv cov npoo sib chwv nrog corrosive media, thaum tswj lub zog siab thiab hnav tsis kam.

Rau qis - muaj kev ntxhov siab, siab} Alloys Lasing (xws li alsi10mg) ua tiav cov qauv lus dag los ntawm kev luam ntawv 3D. Qhov no tswj hwm lub nra thaum siv cov kev ntsuas sab hauv los faib cov kev ntxhov siab, xws li cov khoom siv hluav taws xob ntau thiab cov khoom siv hluav taws xob.

III. Txheej Txheem Syergy: 3D Luam Ntawv Tshuab Ua Ntej Tshaj Tawm Cov Khoom Siv Zoo

Cov khoom siv tsis kam yog muaj txiaj ntsig zoo ntawm kev tswj hwm ntawm 3D cov qauv luam ntawv:

Hmoov qhov loj me Xaiv qhov loj me: hmoov nplua (15 -} {4 4}} precision seem, tab sis nyhav rau agglomerate yooj yim. Coarse hmoov (53 -}}}}} 150μm) muaj cov cua zoo thiab haum rau cov khoom loj. Piv txwv li, thaum luam tawm cobalt-chromium alloy nrog hmoov zoo, nto roughness tuaj yeem tsawg li ra 3.2μm, txo cov coefficient ntawm kev sib txhuam.

Laser Parameter optimization: siab - Melting He point materials {5} {} {} {} {} { Tsawg lub zog siv hluav taws xob ua ke nrog kev ntsuas qeeb nrawm yog tsim rau txhuas alloys, tiv thaiv kev ntxhov siab thermal.

Post -}}}}}}}}}}}}}}}}}}} Kev txhaj tshuaj xws li tua cov npuaj teg thiab cov khoom sib xyaw ua ke, txuas ntxiv txhim kho cov khoom tiv thaiv. Piv txwv li, kev qaug zog lub neej ntawm cov cuab yeej steel tuaj yeem txuas ntxiv los ntawm 50% tom qab kev tua cov npawg. IV. Pitfalls zam kom tsis txhob: Cov lus tsis zoo hauv kev hnav - Cov khoom tiv thaiv xaiv

Hyth 1: qhov siab dua lub hardness, cov kev hnav ntau dua- tiv taus nws yog

Qhov kev sib raug zoo ntawm hardness thiab hnav tsis kam yog tsis yog linear. Piv txwv li, ntshiab titanium muaj qis dua nyuaj dua li stainless hlau, tab sis vim yog tus kheej kho lub peev xwm ntawm nws cov yeeb yaj kiab oxide olide, nws yeej muaj cov coj zoo dua. Kev xaiv kom xaiv tau zoo heev raws li kev sib txhuam hom (swb / yob / cuam tshuam).

HYTH 2: Cov hmoov txawv teb yuav tsum tau ua zoo dua li cov khoom ua haujlwm

Cov tuam txhab hauv tsev tau ua tiav cov kev sib tawg hauv qhov siab - purity hmoov ntau lawm tshuab. Piv txwv li, ib lub chaw tsim khoom tsim alsi60 siab- silicon aluminium alloy hmoov nrog lub purity ntawm 99.9%. Nws cov khoom faib tawm silicon yog cov khoom siv hluav taws xob ntau dua li cov khoom lag luam txawv teb, thiab nws txhawb nqa cov khoom siv 3D luam tau ntau dua.

MYTH 3: Nqis - Cov ntaub ntawv tiv thaiv tsis tuaj yeem ua tiav cov txheej txheem nyuaj

3D luam ntawv cov tseem ceeb tshaj plaws yog nws txoj kev ywj pheej "tsim kev ywj pheej." Los ntawm cov todology optimization, cobalt - chromium alloys tuaj yeem luam tawm cov ris tsho sab hauv, txo cov khoom siv sib txuas lus ua kev tsim.

Xaus: Hnav tsis kam yog cov khoom ntawm cov tshuab engineering.

Cov hnav tsis kam ntawm 3D {{{-}}}}}}}}}}}}}}}}} cov txiaj ntsig ntawm cov khoom sib xyaw, thiab cov txheej txheem - kev siv tshuab. Tsis muaj ib qho yog ib qho yog qhov siv tau yooj yim, tab sis los ntawm kev tshawb fawb cov ntaub ntawv xaiv thiab ua kom ua tau zoo, nws yog qhov ua tau kom ua tiav qhov kev coj ua kom tsis kam rau ib puag ncig ib puag ncig. Rau cov tuam tsev lag luam, ntau dua li kev taug qab cov "hnav feem ntau {{} {} {} {} {} {
