Khoom cim npe

Pt-iridium hlau yog platinum-raws li binary alloy uas muaj selenium. Nws yog ib qho kev daws teeb meem tas li ntawm qhov kub thiab txias. Thaum maj mam txias mus rau 975 ~ 700 ºC, cov khoom theem decomposition tshwm sim, tab sis cov txheej txheem sib npaug ntawm cov txheej txheem maj mam maj mam. Nws tuaj yeem txhim kho corrosion kuj ntawm platinum vim nws yooj yim volatilization thiab oxidation. Muaj Ptlr10, Ptlr20, Ptlr25, Ptlr30 thiab lwm yam alloys, nrog siab hardness thiab siab melting point, siab corrosion kuj thiab tsis tshua muaj kev sib cuag, cov tshuaj corrosion tus nqi yog 58% ntshiab platinum, thiab oxidation poob yog 2.8mg / g. . Nws yog cov khoom siv hluav taws xob sib cuag classic. Siv rau kev sib tiv tauj siab ntawm aero-engines, hluav taws xob tiv tauj ntawm relays nrog siab rhiab heev thiab Wei motors; potentiometers thiab conductive nplhaib txhuam ntawm precision sensors xws li aircraft, missiles thiab gyroscopes

Khoom siv:

Dav siv nyob rau hauv tshuaj nroj tsuag, filaments, spark plugs

(1) Lub txim hluav taws xob tau muab teev los ntawm cov neeg pluag mus rau qhov zoo, ua raws li Jin alloy spark plugs (lub neej expectancy ntawm 30,000 km), platinum spark plugs (lub neej expectancy ntawm 60,000 km), kub spark plugs (lub neej expectancy ntawm 40,000 km) thiab platinum. lub txim taws (lub neej expectancy ntawm 80,000 km)

(2) Siv nyob rau hauv lub txim plug kev lag luam thiab aviation, tshuaj lom neeg kev lag luam, siv lead ua, electromechanical thiab lwm yam kev lag luam (ignition electrode, kub kub thermocouple, hluav taws xob tiv tauj cov ntaub ntawv, filament, siab kub kuj hlau, thiab lwm yam)
