Ka hopena noi o ka nano lanthanum oxide i ka aila lubricating

I ka loaʻa ʻana o ka 362N ka nui o ka pahu pahu pahu ʻai ʻole o ka ʻaila lubricating ʻaila 362N, ʻo 0.720mm ke anawaena o ka wahi wili, a ʻo ke kumu friction he 0.1240, hoʻohui ʻia nā ʻāpana nano-La2O3, a piʻi ka waiwai PB e like me. piʻi ka hapa nui o nā nanoparticles.Loaʻa ka waiwai kiʻekiʻe loa o 510N i ka wā he 0.4% -0.8% ka hapa nui.Ke ʻoi aku ka nui o ka ʻike ma mua o 0.8%, e emi ana ka waiwai PB.ʻO ke anawaena kiko D a me ke kumu friction i hiki i nā kumu waiwai liʻiliʻi o 0.454mm a me 0.0881 ma kahi hakina nui o 0.8%.Hōʻike ke kiʻi i ka hoʻohui ʻana o nā ʻāpana nano-La2O3 i ka ʻaila kumu hiki ke hoʻomaikaʻi i ka hana anti-wear a me ka hoʻohaʻahaʻa friction o ka ʻaila lubricating, a ʻo ka helu hoʻohui maikaʻi loa he 0.8%.Ke hoʻohālikelike ʻia me ka ʻaila kumu, ua hoʻonui ʻia kona waiwai PB e 40.8%, ua hoʻemi ʻia ke anawaena o ka wahi abrasive e 36.9%, a ua hoʻemi ʻia ka coefficient o friction e 29%.

Mechanism kālailai o nanoparticles like lubricant additives

(1) ʻO ka hana hoʻoliʻiliʻi.Hiki i nā ʻāpana Nano-La2O3 ke pāʻani i kahi "micro-polishing" ma ka friction sub-surface, e hoʻomaʻamaʻa i ka ʻili friction a hoʻemi i ka friction.

(2) ʻO ka ʻōnaehana ʻōwili.Ma ka ʻaoʻao o ka lua friction, pāʻani nā ʻāpana nano-La2O3 i kahi "micro-bearing", e hōʻemi ana i ka friction a hoʻomaikaʻi i ka hiki ke amo.

(3) Hoʻoponopono hana.Hiki i nā ʻāpana Nano-La2O3 ke hoʻopiha i nā lua a pāʻani i kahi hana i ka hoʻopiha a hoʻoponopono.

(4) Mekini hana kiʻiʻoniʻoni.Ma lalo o ka hana o ka frictional pressure stress, nano-La2O3 particles with high surface activity is strong adsorbed by particles, forming protective film, hiki ke pale i ka friction surface.
