Amashubhu ensimbi ane-Chrome platedzimbozwe ungqimba lwensimbi ebusweni bensimbi yepayipi lensimbi ngokusebenzisa i-electroplating.Inhloso ebaluleke kakhulu yamapayipi ensimbi ane-chromium ukuvikela.Amapayipi ensimbi ane-Chromium plated anokuqina okuhle kwamakhemikhali futhi awasabeli ku-alkali, ama-sulfide, i-nitric acid, nama-asidi amaningi aphilayo.Amapayipi ensimbi ane-Chromium plated angancibilika ku-hydrochloride acid (efana ne-hydrochloride acid) ne-hot sulfuric acid.Okwesibili, i-chromium Plating inokumelana kahle nokushisa, futhi amapayipi ensimbi ane-chromium plated akhipha umbala kuphela lapho izinga lokushisa lingaphezu kuka-500 degrees Celsius.Ngaphezu kwalokho, i-coefficient yakhe ye-friction, ikakhulukazi i-coefficient eyomile, iphansi kakhulu kuzo zonke izinsimbi, futhi amapayipi ensimbi ane-chrome anokumelana okuhle kakhulu nokugqokwa.Kububanzi bokukhanya obubonakalayo, amandla okubonisa e-chromium angaba ngu-65%, phakathi kwesiliva (88%) ne-nickel (55%).I-Chromium ayiwushintshi umbala, futhi amapayipi ensimbi ane-chrome angakwazi ukugcina amandla awo okubonisa isikhathi eside uma esetshenziswa, okungcono kunesiliva ne-nickel.Kunezinhlobo ezintathu zezinqubo ze-chrome plated.
1. Ukuvikela - Ukuvikelwa Kokuhlobisa I-Chromium Plating - Ukuhlobisa I-Chromium Plating, ngokuvamile eyaziwa ngokuthi I-Chromium Ehlobisayo, inonamathela omncane futhi okhanyayo ovame ukusetshenziswa njengongqimba lwangaphandle lwe-electroplating enezendlalelo eziningi.Ukuze kuzuzwe izinjongo zokuvikela, ungqimba oluphakathi nendawo oluwugqinsi olwanele kufanele lugqitshwe kuqala ku-zinc esekelwe noma i-substrate yensimbi, bese ungqimba olumaphakathi olukhanyayo luka-0.25-0.5 kufanele lubekwe phezu kwalo μ Ungqimba oluncane lwe-chromium lwe-m.Izinqubo ezivame ukusetshenziswa zifaka i-Cu/Ni/Cr, i-Ni/Cu/Ni/Cr, i-Cu Sn/Cr, njll. Ngemva kokupholisha ubuso bomkhiqizo nge-chromium plating yokuhlobisa, kungatholakala ukucwebezela kwesibuko esiluhlaza okwesibhakabhaka.Ayishintshi umbala ngemva kokuchayeka isikhathi eside emkhathini.Lolu hlobo lokumboza lusetshenziswa kabanzi ukuvikela nokuhlobisa izingxenye ezifana nezimoto, amabhayisikili, imishini yokuthunga, amawashi, izinsimbi, kanye nehardware yansuku zonke.Isendlalelo se-chromium esihlotshisiwe sinekhono eliphezulu elikhanyayo lokukhanya futhi singasetshenziswa njengesibonisi.Ukufaka ama-micro pores noma ama-microcracks e-chromium ku-nickel enezingqimba eziningi kuyindlela ebalulekile yokunciphisa ukushuba okuphelele kokumboza nokuthola uhlelo lokuhlobisa olunokuvikela okuphezulu kokubola.Futhi kuyisiqondiso sokuthuthukiswa kwezinqubo zesimanje ze-electroplating.
2. I-chromium eqinile (i-chromium engagugi) inobulukhuni obuphakeme kakhulu nokumelana nokugqokwa, okunganweba impilo yesevisi yezinto zokusebenza, njengamathuluzi okusika nokudweba, ukucindezela nokubumba isikhunta sezinto ezihlukahlukene, ama-bearings, shafts, amageji, amagiya. , njll., futhi ingasetshenziswa futhi ukulungisa ukubekezelelana kobukhulu bezingxenye ezigugile.Ugqinsi lwe-chromium plating eqinile ngokuvamile luyi-5-50 μ m.Kungase futhi kunqunywe ngokuvumelana nezidingo, ezinye eziphakeme njenge-200-800 μ M. Ukufakwa kwe-chromium eqinile ezingxenyeni zensimbi akudingi ukunamathela okuphakathi.Uma kunezidingo ezikhethekile zokumelana nokugqwala, izambatho ezihlukene eziphakathi nazo zingasetshenziswa.
3. Ungqimba olumhlophe lwe-chromium olucwebezelayo lumhlophe qhwa, lunokucwebezela okuphansi, ukuqina okuhle, i-porosity ephansi, nombala othambile.Ukuqina kwayo kuphansi kune-chromium eqinile kanye ne-chromium yokuhlobisa, kodwa inokumelana nokugqwala okuphezulu, ngakho-ke ivame ukusetshenziswa kumathuluzi wokulinganisa namaphaneli wezinsimbi.Ukuze kuthuthukiswe ubulukhuni bayo, ungqimba lwe-chromium eqinile, eyaziwa nangokuthi ungqimba oluphindwe kabili lwe-chromium, lungagcotshwa phezu koqweqwe olumhlophe olune-milky, oluhlanganisa izici zakho kokubili okunamathelayo okumhlophe kwe-chromium okumhlophe kanye ne-chromium eqinile.Ivame ukusetshenziselwa izingxenye zokugqoka ezidinga kokubili ukumelana nokugqoka kanye nokumelana nokugqwala.
4. I-chromium plating enezimbotshana (i-chromium enezimbotshana) isebenzisa izici zokuqhekeka okuhle kongqimba lwe-chromium ngokwayo.Ngemuva kokucwenga i-chromium eqinile, ukwelashwa ngomshini, kwamakhemikhali, noma kwe-electrochemical porosity kuyenziwa ukuze kuqhubeke ukujula nokwandisa inethiwekhi yokuqhekeka.Ingaphezulu lesendlalelo se-chromium limbozwe ngama-grooves abanzi, angagcini nje ngokuba nezici ze-chromium engagugi, kodwa futhi igcina ngempumelelo imidiya yokugcoba, ivimbele ukusebenza okungagcotshisiwe, futhi ithuthukise ukungqubuzana nokumelana nokugqoka kwendawo yokusebenza.Ivamise ukusetshenziselwa ukuhlanganisa ubuso bezingxenye zokungqubuzana kwe-Sliding ngaphansi kwengcindezi enkulu, njengegumbi langaphakathi lombhobho wesilinda wenjini evuthayo, indandatho yepiston, njll.
⑤ I-Plating black chromium i-chromium enamathelayo inokukhanya okufanayo, ukuhlobisa okuhle, nokuqedwa okuhle;Ukuqina kuphakeme kakhulu (130-350HV), futhi ukumelana nokugqoka kuphakeme izikhathi ezingu-2-3 kune-nickel ekhanyayo ngaphansi kobukhulu obufanayo;Ukumelana nokugqwala kwayo kuyafana nokufakwa kwe-chromium okujwayelekile, ikakhulukazi kuya ngokuqina kongqimba oluphakathi nendawo.Ukumelana nokushisa okuhle, akukho ukushintsha kombala ngaphansi kuka-300 ℃.Ungqimba lwe-chromium emnyama lungagcotshwa ngokuqondile phezu kwensimbi, ithusi, i-nickel, nensimbi engagqwali.Ukuze kuthuthukiswe ukumelana nokugqwala kanye nomphumela wokuhlobisa, ithusi, i-nickel, noma i-alloy ye-copper tin ingasetshenziswa futhi njengesendlalelo esingezansi, futhi i-chromium emnyama ingafakwa phezu kwayo.Ukufakwa kwe-chromium emnyama kuvame ukusetshenziselwa ukumboza isivikelo nokuhlobisa izingxenye zamathuluzi endiza kanye nensimbi ye-Optical, amaphaneli okumunca amandla elanga kanye nezidingo zansuku zonke.
