Daim ntawv thov kev cuam tshuam ntawm nano lanthhanum oxide nyob rau hauv lubricating roj

When the maximum card-free bite load PB value of the base oil lubricating oil is 362N, the diameter of the grinding spot is 0.720mm, and the friction factor is 0.1240, the nano-La2O3 particles are added, and the PB value increases as the mass fraction of the nanoparticles increases. Tus nqi siab tshaj plaws ntawm 510N tau mus txog thaum qhov loj feem yog 0.4% -0.8%. Thaum cov ntsiab lus tseem ceeb tshaj 0.8%, tus nqi PB txo qis. Qhov chaw ntawm txoj kab uas hla d thiab qhov kev sib txhuam tau mus txog qhov muaj nuj nqis tsawg kawg nkaus ntawm 0.454mm thiab 0.0881 ntawm qhov feem ntawm 0.8%. Zaj duab piv txwv no qhia tau hais tias qhov sib ntxiv ntawm Nano-La2O3 hais mus rau cov roj hauv cov roj thiab kev sib txhuam kom txo tau cov roj ntawm lubricating, thiab cov roj zoo ntxiv yog 0.8%. Piv nrog rau cov roj hauv paus, nws tus nqi PB tau nce los ntawm 40.8%, lub cheeb ntawm cov kev sib txhuam tsis tau raug txo los ntawm 29%.

Kev ntsuas mechanism ntawm nanoparticts raws li roj nplua nyeem ntxiv

(1) polishing txheej txheem. Nano-La2O3 hais tuaj yeem ua si "polishing" lub luag haujlwm ntawm kev sib txhuam sub-nto, ua kom txhuam hniav thiab txo qhov sib txhuam.

(2) Scrolling mechanism. Nyob rau saum npoo ntawm txoj kev sib txhuam sib txhuam, nano-la2o3 hais ua si ib lub "lub luag haujlwm micro-bearing", txo cov khoom thauj khoom nqa khoom nqa.

(3) Kho lub tshuab kho. Nano-la2o3 hais tuaj yeem sau cov pits thiab ua lub luag haujlwm hauv kev sau thiab kho.

(4) zaj duab xis sib haum tshuab. Nyob rau hauv kev txiav txim ntawm kev sib zog ua haujlwm, Nano-La2O3 hais tawm los ntawm cov kev tiv thaiv siab, uas tuaj yeem tiv thaiv kev sib txhuam.
