Qaybaha Disilicide Molybdenum

Molybdenum Disilicide (MoSi2) waa walax musharrax ah oo rajo leh oo loogu talagalay codsiyada qaab dhismeedka heerkulka sare. Waa meel dhalaalaysa (2030 °C) walxo leh iska caabin oksaydh oo aad u wanaagsan iyo cufnaan dhexdhexaad ah (6.24 g/cm3). Waa mid aan milmi karin asiidhyada intooda badan, laakiin waxay ku milmaan nitric acid iyo hydrofluoric acid. Raadiyeyaasha labada nooc ee atamka aad uma kala duwana, elektronegativity waa mid aad u dhow, waxayna leeyihiin astaamo la mid ah kuwa biraha iyo dhoobada. Molybdenum Disilicide waa mid firfircoon oo waxay samayn kartaa lakabka silikoon dioxide dusha sare ee heerkul sare si looga hortago oksaydh kale. Waxaa loo isticmaalaa in beeraha qalabka daahan anti-oxidation heerkulka-sare, walxaha kululaynta korontada, filimada electrode isku dhafan, qalabka qaab-dhismeedka, qalabka isku dhafan, qalab u adkaysta, qalabka isku xidha dhoobada qaab-dhismeedka iyo beeraha kale.

Molybdenum Disilicide waxaa lagu dabaqi karaa warshado kala duwan oo kala duwan: 1) Tamarta iyo warshadaha kiimikada: MoSi2 waxaa loo isticmaalaa sidii curiyaha kuleylka korantada, kulaylka sare ee aaladda reactor-ka, gaaska gubi, heerkulbeeg heerkul sare ah iyo tuubada ilaalinta, weelka dhalaalaysa (oo loo isticmaalo dhalaalinta sodium, lithium, lead, bismuth, tiin iyo biraha kale) . 2) Warshadaha Microelectronics: MoSi2 iyo Silicides kale oo birta refractory Ti5Si3, WSi2, TaSi2, iwm waa musharrixiinta muhiimka ah ee albaabada wareegga isku dhafan ee baaxadda weyn iyo isku xirnaanta. 3) Warshadaha Aerospace: MoSi2 oo ah maaddada heerkul sare ee ka hortagga oksaydhka, gaar ahaan sida walxaha qaybaha matoorka marawaxadaha, sida daabyada, mashiinnada, qolalka gubashada, tuubooyinka iyo aaladaha wax lagu xidho, ayaa si ballaadhan oo qotodheer u ahaa Cilmi-baadhis iyo codsi. . 4) Warshadaha baabuurta: Molybdenum Disilicide MoSi2 waxaa loo isticmaalaa rotors turbocharger baabuurta, weelka valves, balaastigga iyo qaybaha mishiinka.

Qalab qani ah oo qani ah ayaa ku takhasusay soo saarista Bartilmaameedka Sputtering waxayna soo saari karaan qaybaha Molybdenum Disilicide iyadoo loo eegayo qeexitaanka macaamiisha. Wixii macluumaad dheeraad ah, fadlan nala soo xiriir.
