Umthelela wokusetshenziswa kwe-nano lanthanum oxide emafutheni okugcoba

Lapho inani elikhulu le-PB elilunywa ngaphandle kwekhadi lamafutha okugcoba esisekelo lingu-362N, ububanzi bendawo yokugaya buyi-0.720mm, futhi isici sokushayisana singu-0.1240, izinhlayiya ze-nano-La2O3 ziyengezwa, futhi inani le-PB liyakhula njengoba ingxenye enkulu ye-nanoparticles iyanda.Inani eliphakeme kakhulu lika-510N lifinyelelwa lapho ingxenye enkulu ingu-0.4% -0.8%.Uma okuqukethwe kukukhulu kuno-0.8%, inani le-PB liyehla.Ububanzi bendawo D kanye nesici sokushayisana sifinyelele amanani amancane angu-0.454mm no-0.0881 engxenyeni enkulu engu-0.8%.Umfanekiso ubonisa ukuthi ukungezwa kwezinhlayiya ze-nano-La2O3 kuwoyela wesisekelo kungathuthukisa ukusebenza kokunciphisa ukugqokwa nokunciphisa ukungqubuzana kwamafutha okugcoba, futhi inani eliphelele lokwengeza ngu-0.8%.Uma kuqhathaniswa nowoyela wesisekelo, inani layo le-PB lenyuke ngo-40.8%, ububanzi bendawo eqhumayo behliswa ngo-36.9%, futhi i-coefficient of friction yehliswe ngo-29%.

Ukuhlaziywa kwe-Mechanism ye-nanoparticles njengezithasiselo zokugcoba

(1) Indlela yokupholisha.Izinhlayiya ze-Nano-La2O3 zingadlala indima "yokucwebezela kancane" endaweni engaphansi kwe-friction, yenze indawo yokungqubuzana ibe bushelelezi futhi inciphise ukungqubuzana.

(2) Indlela yokuskrola.Ebusweni be-friction pair, izinhlayiya ze-nano-La2O3 zidlala indima "ye-micro-bearing", ukunciphisa ukungqubuzana nokuthuthukisa umthamo wokuthwala umthwalo.

(3) Indlela yokulungisa.Izinhlayiya ze-Nano-La2O3 zingagcwalisa imigodi futhi zibambe iqhaza ekugcwaliseni nasekulungiseni.

(4) Indlela yokwenza ifilimu.Ngaphansi kwesenzo sokucindezela kokucindezela okungqubuzanayo, izinhlayiya ze-nano-La2O3 ezinomsebenzi ophezulu ongaphezulu zikhangiswa ngokuqinile yizinhlayiya, zakha ifilimu evikelayo, engavikela indawo yokungqubuzana.
