Impeta ya piston ni kimwe mu bice by'ibanze bya moteri. Ibikoresho byimpeta ya piston bigomba kugira imbaraga zikwiye, gukomera, gukomera no kurwanya umunaniro, kwihanganira kwambara neza, kurwanya ubushyuhe no kurwanya ruswa. Hamwe niterambere rya moteri zigezweho zigana umuvuduko mwinshi, umutwaro mwinshi, hamwe n’ibyuka bihumanya ikirere, mugihe ibisabwa kubikoresho bya ring piston bigenda byiyongera kandi hejuru, kuvura hejuru nabyo birasabwa byinshi. Ubuhanga bwinshi kandi bushya bwo kuvura ubushyuhe Bwakoreshejwe cyangwa burimo gukoreshwa mugutunganya ubushyuhe bwimpeta za piston, nka ion nitriding, ceramics yo hejuru, nanotehnologiya, nibindi. Iyi ngingo iragaragaza cyane cyane kwinjiza ceramic ceramic kuvura impeta ya piston.

Piston ring immersion ceramic kuvura ni tekinoroji yo hasi ya plasma ya chimique yohereza imyuka (PCVD mugihe gito). Filime yubutaka ifite ubunini bwa micrometero nyinshi ikura hejuru yicyuma cya substrate. Muri icyo gihe, ubwo ceramic yinjiye mu cyuma, ion z'icyuma nazo zinjira muri ceramic Filime yinjira imbere kandi ikora ikwirakwizwa ry'uburyo bubiri, ihinduka "firime ya cermet". By'umwihariko, inzira irashobora gukura ibyuma bigize ceramic ceramic kubintu byubutaka bwicyuma bigoye kubikoresho bya semiconductor nka chromium gukwirakwira.

Iyi "firime ceramic compte firime" ifite ibintu bikurikira:

1. Gukura ku bushyuhe buke buri munsi ya 300 ℃ nta ngaruka mbi ku mpeta ya piston;

.

3. Kubera ko ceramic yoroheje ya firime nicyuma bigize ibintu bikora bya oblique gradient, ntabwo bigira uruhare muguhuza byimazeyo urwego rwinzibacyuho, ahubwo binanahindura imbaraga zuruhande rwububiko bwa ceramic, biteza imbere kunama, kandi bitezimbere cyane hejuru gukomera no gukomera kw'impeta;

4. Ibyiza byo kwambara ubushyuhe bwo hejuru birwanya;

5. Kongera ubushobozi bwa antioxydeant.

Kuberako firime ya ceramic ifite imikorere yo kwisiga, impeta ya piston yatewe impeta ya piston ceramic irashobora kugabanya coefficente ya friction ya moteri kuri 17% 30%, kandi ubwinshi bwimyambarire hagati yayo na couple yo guterana bugabanukaho 2 / / 5 1 / 2, kandi irashobora kugabanuka cyane. Kunyeganyega kwa moteri n'urusaku. Muri icyo gihe, kubera imikorere myiza yo gufunga hagati ya firime ceramic na moteri ya moteri ya moteri, impuzandengo yo guhumeka ikirere cya piston nayo yagabanutseho 9.4%, kandi ingufu za moteri zirashobora kwiyongera kuri 4.8% 13.3%. Kandi uzigame lisansi 2.2% 22.7%, amavuta ya moteri 30% 50%.
