Iko kushandiswa kwe nano lanthanum oxide mumafuta ekuzora

Kana iyo yakanyanya 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 hwema 0.454mm uye 0.0881 pachikamu chikuru che 0.8%. Mufananidzo wacho unoratidza kuti kuwedzera kwenano-La2O3 zvimedu kumafuta epasi kunogona kuvandudza mashandiro 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-kupolisha" 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 chekumanikidza kudzvinyirira, nano-La2O3 zvimedu zvine basa repamusoro pepamusoro zvakashongedzwa zvine simba nezvimedu, zvichigadzira firimu rinodzivirira, iro rinogona kuchengetedza friction pamusoro.
