Phekolo ea mocheso ke mokhoa o sebetsang haholo oa ho ntlafatsa le ho fetola thepa ea tšepe e chitja ea 15CrMo alloy round steel. E phetha karolo ea bohlokoa haholo ho tšepahala ha lihlahisoa le moruo. Phekolo ea mocheso ea 15CrMo motsoako oa tšepe e pota-potileng hangata e kenyelletsa phekolo e tloaelehileng ea mocheso (annealing, normalizing, quenching, tempering) le phekolo ea mocheso holim'a metsi (ho tima sefahleho le phekolo ea mocheso oa lik'hemik'hale-carburizing, nitriding, metalizing, joalo-joalo).
Boenjiniere ba mechini, likarolo tse ngata tsa mochini, joalo ka li-crankshafts, likere, li-camshaft tsa lienjine tse tukang tse ka hare, le likere tse fokotsang matla, ha li hloke feela boima bo lekaneng, polasetiki le matla a ho kobeha bohareng, empa hape li hloka botenya bo phahameng ka har'a botenya bo itseng. . Ho thatafala, ho hanyetsa ho apara ho phahameng le matla a phahameng a mokhathala. Mekhoa e fapaneng e boletsoeng ka holimo ea phekolo ea mocheso ka kakaretso e thata ho finyella litlhoko tse ka holimo tsa ts'ebetso ka nako e le 'ngoe,' me tšebeliso ea mocheso oa mocheso ke mokhoa o atlehang ka ho fetisisa oa ho finyella litlhoko tsena tsa ts'ebetso ka nako e le 'ngoe.
Phekolo ea mocheso o holim'a metsi ke mokhoa oa ho phekola mocheso o fetolang thepa ea bokaholimo ba tšepe e pota-potileng ea 15CrMo alloy ka ho fetola sebopeho sa lera la bokaholimo.
Ho tima holim'a metsi ke phekolo ea mocheso e fetolang sebopeho sa bokaholimo ka bonngoe ntle le ho fetola lik'hemik'hale tse holim'a metsi. E ka lemohuoa ka maqhubu a phahameng, maqhubu a mahareng kapa mokhoa oa ho futhumatsa motlakase oa hona joale oa ho futhumatsa kapa mokhoa oa ho futhumatsa lelakabe. Ntho e tloaelehileng ke hore bokaholimo ba tšepe e pota-potileng ea 15CrMo e futhumatsoa ka potlako ho mocheso o timang, 'me ha mocheso o sa fetisetsoe karolong e bohareng ea karolo, o pholile ka potlako, e le hore boima ba holim'a metsi bo phahame, empa core e ntse e na le toughness e phahameng.
Phekolo ea lik'hemik'hale ke mokhoa oa ho phekola mocheso o fetolang sebopeho sa lik'hemik'hale le sebopeho sa bokaholimo ba tšepe ea 15CrMo alloy round steel. Phekolo ea mocheso oa lik'hemik'hale e ka aroloa ka mekhoa e kang carburizing, nitriding, carbonitriding, le metalizing ho latela likarolo tse fapaneng tse kenngoeng holim'a tšepe e pota-potileng ea 15CrMo. E sebetsa haholo bakeng sa ho ntlafatsa le ho ntlafatsa ho hanyetsa ho roala, ho hanyetsa kutu le ho hanyetsa mokhathala oa 15CrMo alloy round steel. Hona joale, phekolo ea mocheso oa lik'hemik'hale e tsoetse pele ka potlako, 'me ho na le mekhoa e mengata ea theknoloji e ncha.
