Daim ntawv thov cov nyhuv ntawm nano lanthanum oxide nyob rau hauv lubricating roj

Thaum lub siab tshaj plaws daim npav tsis pub tom load PB tus nqi ntawm lub hauv paus roj lubricating roj yog 362N, txoj kab uas hla ntawm qhov chaw sib tsoo yog 0.720mm, thiab qhov sib txhuam yog 0.1240, nano-La2O3 hais ntxiv, thiab PB tus nqi nce ntxiv. qhov loj feem ntawm nanoparticles nce. Qhov siab tshaj plaws tus nqi ntawm 510N yog mus txog thaum qhov loj feem yog 0.4% -0.8%. Thaum cov ntsiab lus ntau dua 0.8%, PB tus nqi txo. Qhov chaw txoj kab uas hla D thiab qhov sib txhuam qhov tseem ceeb mus txog qhov tsawg kawg nkaus qhov tseem ceeb ntawm 0.454mm thiab 0.0881 ntawm ib feem ntawm 0.8%. Cov duab qhia tau hais tias qhov sib ntxiv ntawm nano-La2O3 hais rau cov roj hauv paus tuaj yeem txhim kho cov kev tiv thaiv kev hnav thiab kev sib txhuam txo kev ua haujlwm ntawm cov roj lubricating, thiab qhov zoo tshaj qhov ntxiv yog 0.8%. Piv nrog rau cov roj hauv paus, nws tus nqi PB tau nce los ntawm 40.8%, txoj kab uas hla ntawm qhov chaw abrasive raug txo los ntawm 36.9%, thiab cov coefficient ntawm kev sib txhuam yog txo los ntawm 29%.

Mechanism tsom xam ntawm nanoparticles li lubricant additives

(1) Polishing mechanism. Nano-La2O3 hais tuaj yeem ua lub luag haujlwm "micro-polishing" ntawm kev sib txhuam sub-surface, ua rau kev sib txhuam nto smoother thiab txo kev sib txhuam.

(2) Scrolling mechanism. Nyob rau saum npoo ntawm kev sib txhuam khub, nano-La2O3 hais ua si lub luag haujlwm "micro-bearing", txo kev sib txhuam thiab txhim kho lub peev xwm nqa.

(3) Kho mechanism. Nano-La2O3 hais tuaj yeem sau rau hauv qhov pits thiab ua lub luag haujlwm hauv kev sau thiab kho.

(4) Zaj duab xis tsim mechanism. Nyob rau hauv qhov kev txiav txim ntawm kev sib txhuam kev nyuaj siab, nano-La2O3 hais nrog cov kev ua haujlwm siab saum npoo yog muaj zog adsorbed los ntawm cov khoom, tsim cov yeeb yaj kiab tiv thaiv, uas tuaj yeem tiv thaiv kev sib txhuam nto.
