Cov Cim Npe Khoom

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

Khoom siv:

Siv dav hauv cov nroj tsuag tshuaj, filaments, spark plugs

(1) Cov roj teeb raug xaiv los ntawm qhov tsis zoo mus rau qhov zoo, ua raws li Jin alloy roj teeb (lub neej ntev txog 30,000 km), platinum roj teeb (lub neej ntev txog 60,000 km), kub roj teeb (lub neej ntev txog 40,000 km) thiab platinum roj teeb (lub neej ntev txog 80,000 km).

(2) Siv rau hauv kev lag luam hluav taws xob thiab kev lag luam aviation, kev lag luam tshuaj lom neeg, siv lead ua, electromechanical thiab lwm yam teb (hluav taws xob hluav taws xob, thermocouple kub siab, cov khoom siv hluav taws xob, filament, hlau tiv taus kub siab, thiab lwm yam)
