Lub zog tshiab ntawm cov hlau yog 100 lub sijhawm ntau dua li cov kub loj dua cov hlau

Cov kws tshawb nrhiav ntawm Sandia National Laboratory tau pom lub tshuab sim ua lub computer siv los kwv yees kev hnav tsis tau dhau los ntawm lawv cov platinum alloys, ib yam li ib puag ncig ntsuas khoom siv los ua kom pom tseeb.

Lub platinum alloy tsim los ntawm cov kws tshawb fawb Asmeskas yog thawj cov hlau ua hlau uas yog tib yam li pob zeb diamond thiab sapphire thiab muaj hnav tsis kam.

Ib pab neeg tshawb fawb los ntawm Sandia National Laboratory hauv New Mexico ntseeg tias cov khoom siv no yog 100 lub sijhawm ntev dua li lub zog loj dua hlau thiab yog cov hlau hnav tshaj plaws hauv ntiaj teb.

GG quot; Peb pom tias koj tuaj yeem hloov kho rau qee cov alloys uas yuav ua tiav kev txhim kho ntau hauv kev ua tau zoo ntawm ntau cov khoom siv hlau tiag tiag," hais tias cov kws tshawb fawb cov ntaub ntawv xov xwm Nic Argibay, uas tshaj tawm Cov Ntawv Tshawb Fwm Kev Tshawb Fawb hauv cov ntaub ntawv tsis ntev los no. Cov.

Txawm hais tias cov hlau muaj zog, lawv hnav thaum xeb tawm tsam lwm cov hlau tshwj tsis yog tias lawv tau nruab nrog cov thaiv lossis tiv thaiv kom zoo xws li cov roj lub cev muaj zog. Rau cov khoom siv hluav taws xob, cov txheej no feem ntau yog ua los ntawm kub lossis lwm yam khoom muaj nqi, thiab nws yuav hnav dhau sijhawm.

Argibay tau hais tias Sandia platinum txheej tiv thaiv tuaj yeem txuag kev lag luam hluav taws xob ntau dua $ 100 lab hauv cov khoom txhua xyoo thiab ua kom cov khoom lag luam ruaj khov thiab txhim khu kev qha.

GG quot; Cov khoom siv coj los tiv no yuav ua rau muaj kev ntseeg tau zoo rau ntau yam ntawm cov cuab yeej peb tau tshawb," hais tias Sandia engineer Chris Nordquist uas tsis koom nrog txoj kev tshawb nrhiav no." Cov caij nyoog rau kev sib xyaw thiab kev txhim kho yuav nyob ntawm lub cuab yeej, tab sis cov khoom siv no yuav muab lwm lub cuab tam los daws qhov tam sim no kev ntseeg tau cov kev txwv ntawm cov khoom siv hlau microelectronic."

Txawm hais tias lawv cov sib xyaw ntawm 90% platinum thiab 10% kub tsis yog qhov tshiab, txoj kev xav hauv qab nws yog. Argibay thiab nws tus kws sau yawg Michael Chandross tau tawm tsam kev txawj ntse, uas tau txiav txim siab tias lub peev xwm ntawm cov hlau los tiv thaiv kev txhuam yog nyob ntawm nws cov hardness. Ntawm qhov tsis sib xws, lawv ntseeg hais tias kev coj hnav muaj feem xyuam nrog kev tiv thaiv tshav kub ntawm cov hlau, thiab lawv tau tsim lub alloy coj los ua qhov no.

GG quot; Ntau cov tsoos tsoos tau raug tsim los txhim kho lub zog ntawm cov khoom los ntawm kev txo qhov me me hauv qhov loj me," hais John Curry, Sandia' s lub sij hawm tom qab teem caij sib tham thiab sau ua ntej ntawm daim ntawv." Txawm li ntawd los, thaum lub siab hnyav thiab qhov kub thiab txias, ntau cov alloys yuav dhau los ua tuab lossis muag muag, tshwj xeeb tshaj yog thaum rog rog. Peb tau pom tias nrog peb cov platinum alloys, cov neeg kho tshuab thiab thermal stability zoo heev, thiab thaum lub sijhawm swb, Peb tsis pom ntau yam pauv hauv microstructure nyob rau lub sijhawm ntev-kev ntxhov siab.
