Ungabubamba kanjani ubukhulu be-chrome plating ukuze uthole ukunemba kwe-piston rod machining

I-Precision piston rod okwamanje isetshenziswa ezimbonini eziningi emkhiqizweni, kungenxa yokuthi induku ye-piston isetshenziswa kabanzi, ngakho-ke abantu bokukhethwa kwezinto zokukhiqiza induku ye-piston nakho kubhekwe kakhulu ekukhethweni kwezinto zokukhiqiza ezahlukahlukene, bese ukukhiqizwa kwayo. ukusebenza kahle kwenduku yepiston nezici nazo zihlukile.

I-45 # insimbi iyinsimbi yesakhiwo se-carbon, ipholile futhi ishisa ukusebenza kokucubungula, izakhiwo zemishini, amandla aphezulu.45# insimbi ekucimeni ngaphandle kokufudumeza ngaphambili, ubulukhuni obukhulu kune-HRC55 kwabaqeqeshiwe, futhi ngemva kokwelashwa kokushisa, bese ukucisha kungafinyelela ku-HRC42-46, ukuze induku yepiston enembayo ibe nezakhiwo ezinhle zomshini nobulukhuni.

I-40Cr iyinsimbi ephakathi kwe-carbon tempered, ngemuva kokwelashwa okushisa okufanele, ungathola ukuqina okuhle, ipulasitiki.Futhi ingaba nezakhiwo ezinhle eziphelele zemishini ngemva kokwelashwa kokushisa, ukuqina okuhle komthelela ophansi wokushisa.Ngaphezu kwalokho, le nsimbi ifanelekela i-cyanidation kanye nokwelashwa kokucisha imvamisa ephezulu ngaphezu kokwelashwa kokuthambisa.

Insimbi ye-GCr15 iwuhlobo lokuqukethwe kwengxubevange engaphansi kwekhabhoni chromium enensimbi enensimbi, enokuqina okuphakeme uma kuqhathaniswa, ngemva kokwelashwa kokushisa kungatholwa ngemva kokuqina okuphezulu nokufana okufanayo.Futhi uma icishwa kanye nokwelashwa okufudumele kokushisa okuphansi, ingaba nobunzima obuphezulu, ukuhlelwa okufanayo kanye nezindawo zokukhathala ezithinta kakhulu ezinolaka.

I-Sus304 inokumelana nokugqwala okuphakeme kuqhathaniswa, ingaba kuzinga lokushisa eliphansi, izinga lokushisa legumbi kanye nezinga lokushisa eliphakeme ipulasitiki ephezulu kanye nokuqina kanye nokwakheka okungcono okubandayo nokushisela.Ngenxa yokuthi i-austenite yayo ayinalo ushintsho lwesigaba lapho ishiswa, izinduku zepiston ezinembayo azikwazi ukuqiniswa ukwelashwa kokushisa futhi zingaphathwa ngokushisa kuphela ukuze kuqiniswe ukumelana nokugqwala kwensimbi.

Ugqinsi lwe-chrome plating yenqubo ye-piston rod enembayo kufanele inqunywe ngokuhambisana nokwangempela.Enqubweni yokucwenga ye-piston ye-chrome, ukujiya kongqimba lwe-chrome kunobudlelwano obuseduze nobulukhuni bobuso benduku.Uma kwenziwa i-chrome plating, lokhu kunganqunywa ngokuya ngezidingo zekhasimende ukuze kuzuzwe ukusebenza okuhle kwekhwalithi.
