Isiphumo sokusetyenziswa kwe-nano lanthanum oxide kwioli yokuthambisa

Xa ubuninzi bekhadi-free bite umthwalo PB ixabiso lesiseko yeoli yokuthambisa ioli yi-362N, ububanzi bendawo yokugaya yi-0.720mm, kwaye i-friction factor yi-0.1240, iinqununu ze-nano-La2O3 zongezwa, kwaye ixabiso le-PB landa njengoko inxalenye enkulu ye-nanoparticles iyanda.Ixabiso eliphezulu le-510N lifikeleleke xa i-mass fraction i-0.4% -0.8%.Xa umxholo mkhulu kune-0.8%, ixabiso le-PB liyancipha.Ububanzi bendawo D kunye ne-friction factor ifikelele kumaxabiso amancinci angama-0.454mm kunye ne-0.0881 kwi-fraction mass ye-0.8%.Umzobo ubonisa ukuba ukongezwa kwe-nano-La2O3 i-particle kwi-oyile yesiseko kunokuphucula ukusebenza kwe-anti-wear and friction yokunciphisa i-oyile yokuthambisa, kunye neyona mali yokongeza i-0.8%.Xa kuthelekiswa neoli yesiseko, ixabiso layo le-PB linyuswe ngu-40.8%, ububanzi bendawo enqabileyo yancitshiswa ngu-36.9%, kwaye i-coefficient of friction yancitshiswa nge-29%.

Uhlalutyo lwe-Mechanism ye-nanoparticles njengezongezo ze-lubricant

(1) Indlela yokugudisa.Iincinci ze-Nano-La2O3 zinokudlala indima "ye-micro-polish" kwi-friction sub-surface, okwenza ukuba indawo ye-friction ibe lula kunye nokunciphisa ukungqubuzana.

(2) Indlela yokuskrola.Kwindawo yokudibanisa i-friction, i-nano-La2O3 i-particle idlala indima "ye-micro-bearing", ukunciphisa ukuxhatshazwa kunye nokuphucula umthamo wokuthwala umthwalo.

(3) Indlela yokulungisa.Iinqununu ze-Nano-La2O3 zinokuzalisa imigodi kwaye zidlale indima ekuzaliseni nasekulungiseni.

(4) Indlela yokwenza ifilimu.Ngaphantsi kwesenzo soxinzelelo loxinzelelo lwe-frictional, i-nano-La2O3 iinqununu ezinomsebenzi ophezulu ophezulu zikhangiswa ngamandla ngamaqhekeza, zenza ifilimu ekhuselayo, enokukhusela umphezulu we-friction.
