Saamaynta daaweynta cryogenic ee hagaajinta tayada carbide sibidhka

Laga soo bilaabo 1980-meeyadii, daaweynta cryogenic ayaa si guul leh loo isticmaalay si loo hagaajiyocarbide sibidhka ah.Daraasado badan ayaa muujiyay in daaweynta cryogenic ay leedahay saameyn togan oo gaar ah oo ku saabsan sifooyinka farsamada, xirashada caabbinta, goynta waxqabadka, qaab-dhismeedka yar-yar, iyo xaaladaha walaaca haraaga ee karbide sibidhka.Iyada oo loo marayo sahaminta joogtada ah ee cilmi-baarayaashu, taxane qiimeyaal wax ku ool ah ayaa la helay.iyo gunaanadka muhiimadda sayniska.

(1) Daaweynta Cryogenic waxay hagaajin kartaa xoogga foorarsiga, xirto iska caabbinta iyo jarida waxqabadkacarbide sibidhka ah, si wax ku ool ah loo kordhiyo nolosha adeegga eeqalabka carbide sibidhka.Iyadoo la falanqeynayo saameynta hababka daaweynta cryogenic ee sifooyinka farsamada ee carbide cemented, waxaa la rumeysan yahay in saameynta hagaajinta ee daaweynta cryogenic aysan si toos ah u beddelin hoos u dhaca heerkulka daaweynta cryogenic iyo kordhinta waqtiga haynta.Waayo, darajooyin gaar ah oocarbide sibidhka ah, waxaa jira habka ugu wanaagsan ee daaweynta cryogenic, kaas oo ku gaari kara saameynta ugu wanaagsan ee qiimaha jaban.

(2) Saamaynta ugu weyn ee daaweynta cryogenic ee qaab-dhismeedka yar yar eecarbide sibidhka ahwaa: ① beddelidda qaab-dhismeedka hadhuudhka ee marxaladda adag - WC;② kor u qaadista isbeddelka martensitic ee marxaladda isku xidhka;③ Qurub carbide oo wanaagsan (wejiga eta) oo ku kala firirsan oo ku degdegay matrixka walxaha.

(3) Isbeddelka martensite ee marxaladda isku-xidhka, roobabka carbides-ka ganaaxa iyo kororka cadaadiska haraaga ah ee dusha walxaha ka dib daaweynta cryogenic waxay si weyn u wanaajin kartaa xoogga iyo xirashada caabbinta carbide sibidhka.Sidaa darteed, hagaajinta sifooyinka macroscopic ee carbide cemented waa natiijada saameynta isku dhafan ee xoojinta isbeddelka wajiga iyo xoojinta cadaadiska.
