Iringi yepiston yenye yeendawo eziphambili ze-injini. Izinto eziphathekayo zeringi yepiston kufuneka zibe namandla afanelekileyo, ukuqina, ukuqina kunye nokumelana nokudinwa, ukuxhathisa okugqwesileyo, ukumelana nobushushu kunye nokumelana nokugqwala. Ngophuhliso lweenjini zale mihla ukuya kwisantya esiphezulu, umthwalo ophezulu, kunye nokukhutshwa okuphantsi, ngelixa iimfuno zezixhobo zeringi zepiston zisiba phezulu nangaphezulu, unyango lwangaphezulu lukwaxhomekeke kwiimfuno eziphezulu. Ithekhnoloji entsha yonyango lobushushu sele isetyenziswa okanye isetyenziswa kunyango lobushushu lwemisesane yepiston, efana ne-ion nitriding, iiseramiki zomphezulu, i-nanotechnology, njl.

Piston ring ukuntywiliselwa unyango ceramic bubushushu obuphantsi plasma chemical deposition technology umphunga (PCVD ngokufutshane). Ifilimu ye-ceramic enobunzima bee-micrometers ezininzi ikhuliswe kumphezulu we-metal substrate. Ngexesha elifanayo xa i-ceramic ingena kwi-metal surface, i-ion zetsimbi nazo zingena kwi-ceramic Ifilimu ingena ngaphakathi kwaye yenza i-diffusion yeendlela ezimbini, ibe "ifilimu edibeneyo ye-cermet". Ngokukodwa, inkqubo inokukhulisa i-metal composite ye-ceramic imathiriyeli kwi-substrate yesinyithi enzima kwizinto ze-semiconductor ezifana ne-chromium ukuba isasazeke kuyo.

Le "ifilimu edibeneyo ye-ceramic ye-ceramic" ineempawu ezilandelayo:

1. Ukukhula kubushushu obuphantsi obungaphantsi kwe-300℃ ngaphandle kwempembelelo embi kwindandatho yepiston;

2. Intsimbi ebusweni bendandatho yepiston ihamba ngeendlela ezimbini zokusasazwa kunye ne-boron nitride kunye ne-cubic silicon nitride kwi-vacuum plasma state, eyenza izinto ezisebenzayo kunye ne-gradient gradient, ngoko idibene ngokuqinileyo;

3. Ngenxa yokuba ifilimu ye-ceramic ebhityileyo kunye nentsimbi yenze i-oblique gradient esebenzayo, ayidlali kuphela indima ekubopheni ngokuqinileyo umaleko wenguqu, kodwa iphinde iguqule amandla omgca we-ceramic bond, iphucula ukuxhathisa ukugoba, kwaye iphucula kakhulu umphezulu. ubunzima kunye nokuqina komsesane;

4. Kungcono ukumelana nobushushu obuphezulu;

5. Ukomelezwa kwe-antioxidant umthamo.

Ngenxa yokuba ifilimu ye-ceramic inomsebenzi wokuzithambisa, i-piston ring efakwe kwi-ceramic piston ring inokunciphisa i-coefficient ye-friction ye-injini nge-17% 30%, kwaye ubungakanani bokunxiba phakathi kwayo kunye ne-friction pair iyancipha nge-2/ / 5 1/2, kwaye inokuncitshiswa kakhulu. Ukungcangcazela kwe-injini kunye nengxolo. Kwangaxeshanye, ngenxa yokusebenza kakuhle kokutywinwa phakathi kwefilimu yeceramic kunye nelayini yesilinda se-injini, umndilili wokuvuza komoya wepiston nawo wehle nge-9.4%, kwaye amandla e-injini anokonyuka nge-4.8% 13.3%. Kwaye wonge amafutha 2.2% 22.7%, i-oyile ye-injini 30% 50%.
