Nā ʻano o ka lubricant i hana ʻia mai ka flake graphite

Nui nā ʻano lubricant paʻa, ʻo ka flake graphite kekahi o lākou, aia pū kekahi i loko o nā mea hoʻemi friction i ka pauka metallurgy i ka mea mua e hoʻohui i kahi lubricant paʻa. Loaʻa i ka flake graphite kahi ʻano lattice papa, a maʻalahi ka hāʻule ʻana o ka kristal graphite papa ma lalo o ka hana o ka ikaika friction tangential. Hōʻoia kēia i ka flake graphite ma ke ʻano he lubricant he coefficient haʻahaʻa o ka friction, maʻamau 0.05 a 0.19. I ka vacuum, emi ka coefficient friction o ka flake graphite me ka hoʻonui ʻana o ka mahana mai ka mahana o ka lumi a i ka mahana hoʻomaka o kona sublimation. No laila, ʻo ka flake graphite kahi lubricant paʻa kūpono i ka mahana kiʻekiʻe.
He kiʻekiʻe ke kūpaʻa kemika o ka flake graphite, he ikaika ka ikaika o ka hoʻopaʻa ʻana i ka molekala me ka metala, e hana ana i kahi papa o ka ʻili lubrication ma luna o ka ʻili metala, e pale pono ana i ke ʻano kristal, a e hana ana i nā kūlana friction flake graphite a me ka graphite.
ʻO kēia mau waiwai maikaʻi loa o ka flake graphite ma ke ʻano he lubricant e hoʻohana nui ʻia ai i nā mea o nā ʻano like ʻole. Akā ʻo ka hoʻohana ʻana i ka FLAKE graphite ma ke ʻano he lubricant paʻa he mau hemahema nō hoʻi ia, ʻo ka mea nui i ka vacuum flake graphite friction coefficient he pālua ia o ka ea, hiki ke hoʻohana ʻia a hiki i nā haneli manawa, ʻo ia hoʻi, ua hoʻopilikia nui ʻia ka lubrication ponoʻī o ka flake graphite e ka lewa. Eia kekahi, ʻaʻole lawa ka pale ʻana o ka flake graphite ponoʻī, no laila pono e hui pū ʻia me ka matrix metala e hana i ka mea lubrication ponoʻī paʻa metala/graphite.
