Àgwà nke mmanụ e ji flake graphite mee

anyị

E nwere ọtụtụ ụdị mmanụ siri ike, flake graphite bụ otu n'ime ha, ọ bụkwa ihe eji ebelata esemokwu ntụ ntụ na mbụ iji tinye mmanụ siri ike. Flake graphite nwere nhazi lattice dị larịị, ọdịda nke kristal graphite dịkwa mfe ime n'okpuru ọrụ nke ike esemokwu tangential. Nke a na-eme ka graphite flake dị ka mmanụ nwere obere coefficient nke esemokwu, nke na-abụkarị 0.05 ruo 0.19. Na oghere ikuku, coefficient esemokwu nke flake graphite na-ebelata ka okpomọkụ na-abawanye site na okpomọkụ ụlọ ruo na okpomọkụ mmalite nke sublimation ya. Ya mere, flake graphite bụ mmanụ siri ike zuru oke na okpomọkụ dị elu.
Nkwụsi ike kemịkalụ nke flake graphite dị elu, o nwere ike njikọ molekul siri ike na ígwè, na-emepụta oyi akwa nke ihe nkiri mmanụ n'elu ígwè ahụ, na-echebe nhazi kristal nke ọma, ma na-emepụta ọnọdụ esemokwu flake graphite na graphite.
Njirimara ndị a dị mma nke flake graphite dị ka mmanụ na-eme ka e jiri ya mee ihe n'ọtụtụ ihe dị iche iche. Mana iji flake graphite dị ka mmanụ siri ike nwekwara adịghị ike nke ya, ọkachasị na vacuum flake graphite friction coefficient bụ okpukpu abụọ nke ikuku, mmebi nwere ike ịdị ruo ọtụtụ narị ugboro, ya bụ, ikuku na-emetụta mmanụ flake graphite n'onwe ya nke ukwuu. Ọzọkwa, iguzogide iyi nke flake graphite n'onwe ya ezughị ezu, yabụ a ga-ejikọta ya na matrix metal iji mepụta ihe siri ike na-eme ka mmanụ sie ike nke metal/graphite.
