Nyanzvi yehunyanzvi inofanirwa kuziva kuti pamusoro peiyo yekubatanidza yekubatanidza inotaridzika yakatsetseka, asi 5-10 micron bulge inogona kuramba ichionekwa pasi pemaikorosikopu.Muchokwadi, hapana chinhu chakadai sechinhu chakachena chesimbi mumhepo uye kunyangwe simbi yakachena kwazvo, kana yangoiswa mumhepo, inokurumidza kuumba yekutanga oxide firimu yemamicrons mashoma.Semuenzaniso, mhangura inongotora 2-3 maminetsi, nickel anenge 30 maminetsi, uye aruminiyamu inongotora 2-3 masekonzi kuumba oxide firimu rine ukobvu anenge 2 microns pamusoro payo.Kunyangwe kunyanya yakagadzikana yakakosha goridhe goridhe, nekuda kweiyo yakakwirira pamusoro pesimba, iyo nzvimbo yekumusoro ichagadzira dhizaini ye organic gasi adsorption firimu.Connector contact resistance components zvinogona kukamurwa kuva: concentrated resistance, film resistance, conductor resistance.Kazhinji kutaura, zvinhu zvikuru zvinokanganisa iyo yekubatanidza yekubatanidza kuramba bvunzo ndeaya anotevera.
1. Positive stress
Iko kudzvanywa kwakanaka kwekubatana isimba rinoitwa nepamusoro pekubatana kune mumwe nemumwe uye perpendicular kune yekusangana kwepamusoro.Nekuwedzera kwekumanikidza kwakanaka, iyo nhamba uye nzvimbo yekuonana micro-mapoinzi zvishoma nezvishoma inowedzera, uye yekuonana madiki mapoinzi shanduko kubva kune elastic deformation kuenda kupurasitiki deformation.Kurambana kwekubata kunodzikira sezvo kudzikira kweconcentration resistance.Iyo yakanaka yekubata kumanikidza inonyanya kuenderana neiyo geometry yekusangana uye zvinhu zvemukati.
2. Chimiro chepamusoro
Iyo yepamusoro yekubata ifirimu yakasununguka yepamusoro inogadzirwa ne mechanical adhesion uye deposition yeguruva, rosin uye mafuta pamusoro pekubatana.Iyi bhaisikopo repamusoro firimu iri nyore kuisirwa mukati meiyo midiki magomba eiyo yekubata kumeso nekuda kweiyo tunhu, iyo inoderedza nzvimbo yekubata, inowedzera kuramba kwekubata, uye haina kugadzikana zvakanyanya.Yechipiri ifirimu rekusvibisa rakagadzirwa nekushambadza kwemuviri uye makemikari adsorption.Iyo simbi yepamusoro inonyanya kuvekemikari adsorption, iyo inogadzirwa nekutama kwerekitironi mushure mekushambadza kwemuviri.Naizvozvo, kune zvimwe zvigadzirwa zvine kuvimbika kwepamusoro zvinodiwa, senge aerospace yemagetsi ekubatanidza, panofanirwa kuve neakachena kugadzirwa kwemamiriro ekunze mamiriro, yakakwana yekuchenesa nzira uye inodiwa yekuisa chisimbiso matanho, uye kushandiswa kwemayuniti kunofanirwa kuve nekuchengetera kwakanaka uye kushandiswa kwekushanda kwemamiriro ekunze.
