Iko kushandiswa kwe nano lanthanum oxide mumafuta ekuzora

Kana iyo yakakura kadhi-isina kuruma mutoro PB kukosha kweiyo base mafuta ekuzora mafuta iri 362N, dhayamita yenzvimbo yekukuya iri 0.720mm, uye friction factor iri 0.1240, iyo nano-La2O3 zvidimbu zvinowedzerwa, uye kukosha kwePB kunowedzera se chikamu chikuru che nanoparticles chinowedzera.Nhamba yepamusoro ye510N inosvika apo chikamu chemazana chiri 0.4% -0.8%.Kana zvirimo zvakakura kupfuura 0.8%, kukosha kwePB kunoderera.Iyo nzvimbo yedhayamita D uye friction factor yakasvika pahushoma hunokosha hwe 0.454mm uye 0.0881 pachikamu chikuru che 0.8%.Mufananidzo wacho unoratidza kuti kuwedzera kwenano-La2O3 zvimedu kumafuta epasi kunogona kuvandudza maitiro e-anti-kupfeka uye friction yekudzikisa kwemafuta ekuzora, uye iyo yakakwana yekuwedzera huwandu ndeye 0.8%.Kuenzaniswa nemafuta ekutanga, kukosha kwayo kwePB kwakawedzera ne40.8%, dhayamita yenzvimbo inoputika yakaderedzwa ne36.9%, uye coefficient of friction yakaderedzwa ne29%.

Mechanism yekuongorora nanoparticles semafuta ekuwedzera

(1) Kupukuta michina.Nano-La2O3 zvimedu zvinogona kutamba "micro-polish" basa pane friction sub-surface, zvichiita kuti friction pamusoro iite mushe uye kuderedza kukwesha.

(2) Kuscrolling mechanism.Pamusoro peiyo friction pair, iyo nano-La2O3 zvidimbu zvinotamba "micro-bearing" basa, kuderedza kukweshera uye kugadzirisa mutoro wekutakura.

(3) Kugadzirisa nzira.Nano-La2O3 zvimedu zvinogona kuzadza makomba uye kuita basa mukuzadza nekugadzirisa.

(4) Mafirimu ekugadzira nzira.Pasi pechiito che frictional pressure stress, nano-La2O3 zvimedu zvine basa repamusoro pepamusoro zvakashongedzwa zvakasimba nezvimedu, zvichigadzira firimu rinodzivirira, rinogona kuchengetedza friction surface.
