Kukho iintlobo ezininzi ze-solid lubricant, i-flake graphite yenye yazo, ikwakwi-powder metallurgy friction materials kwi-first to add a solid lubricant. I-Flake graphite inesakhiwo se-lattice esine-layered, kwaye ukungaphumeleli kwe-grafite crystal kulula ukwenzeka phantsi kwesenzo samandla e-tangential friction. Oku kuqinisekisa ukuba i-flake graphite njenge-lubricant ine-coefficient ephantsi ye-friction, ngokuqhelekileyo ukusuka kwi-0.05 ukuya kwi-0.19. Kwi-vacuum, i-coefficient ye-friction ye-flake graphite iyancipha ngokunyuka kobushushu ukusuka kubushushu begumbi ukuya kubushushu bokuqala be-sublimation yayo. Ke ngoko, i-flake graphite yi-solid lubricant efanelekileyo kubushushu obuphezulu.
Uzinzo lweekhemikhali ze-flake graphite luphezulu, lunamandla amakhulu okubopha iimolekyuli ngesinyithi, lwenza umaleko wefilimu yokuthambisa phezu komphezulu wesinyithi, lukhusela ngokufanelekileyo isakhiwo sekristale, kwaye lwenza iimeko zokungqubana kwe-flake graphite kunye ne-graphite.
Ezi mpawu zibalaseleyo ze-flake graphite njenge-lubricant zenza ukuba isetyenziswe kakhulu kwizinto ezahlukeneyo. Kodwa UKUSEBENZISA i-FLAKE graphite njenge-lubricant eqinileyo kuneziphene zayo, ikakhulu kwi-vacuum flake graphite friction coefficient iphindwe kabini kuneyomoya, ukuguguleka kunokuba ngaphezulu kwamaxesha amaninzi, oko kukuthi, ukuzithambisa kwe-flake graphite kuchaphazeleka kakhulu ngumoya. Ngaphezu koko, ukumelana nokuguguleka kwe-flake graphite ngokwayo akwanelanga, ngoko ke kufuneka idityaniswe ne-metal matrix ukwenza izinto ezizithambisayo zesinyithi/i-graphite.
