Ukwelashwa Okujwayelekile Kwe-Metal Surface

Umqondo wokwelashwa kwendawo yensimbi

Isho inqubo yokushintsha isimo esingaphezulu nezici zengxenye nokuthuthukisa ukuhlanganiswa kwayo nokokusebenza kwe-matrix ukuze kuhlangatshezwane nezimfuneko zokusebenza ezinqunywe kusengaphambili ngokusebenzisa ubuchwepheshe obusha obusezingeni eliphezulu ku-physics yesimanje, ikhemistri, i-metallurgy, nokwelashwa kokushisa.

1. Metal Surface Ukuguqulwa

Iqukethe izindlela ezilandelayo: ukuqina kwendawo, ukuqhunyiswa kwesihlabathi, ukugoqa, ukudweba ngocingo, ukupholisha, ukuqina kwe-laser

(1) ukuqina kwendawo yensimbi

Kuyindlela yokwelapha ukushisa eyenza i-austenitizes ungqimba olungaphezulu futhi iphole ngokushesha ukuze iqine ngaphandle kokushintsha ukwakheka kwamakhemikhali ensimbi.

(2) indawo yensimbi eqhunyiswe ngesihlabathi

I-workpiece surface ithintwa isihlabathi esinesivinini esiphezulu nezinhlayiya zensimbi, ezingasetshenziswa ukuthuthukisa izakhiwo zemishini zengxenye futhi ziguqule isimo esiphezulu. Lokhu kusebenza kungathuthukisa ngempumelelo amandla emishini, ukumelana nokugqoka futhi kuqede ukucindezeleka okusele.

(3) ukugingqika kwendawo yensimbi

Ukucindezela ubuso be-workpiece nge-roller eqinile ekamelweni lokushisa ukuze ubuso be-workpiece bube lukhuni ngokuguqulwa kwepulasitiki ukuze kutholakale indawo enembile nebushelelezi.

(4) indawo yensimbi ebhulashiwe

Ngaphansi kwamandla angaphandle, insimbi iphoqelelwa ngokufa. I-cross-section yensimbi iyacindezelwa ukuze iguqule ukuma nobukhulu bayo. Le ndlela ibizwa ngokuthi ukudweba ngocingo. Ngokwezidingo zokuhlobisa, ukudweba ngocingo kungenziwa kube izintambo ezihlukahlukene, ezifana neqondile, i-crimped, i-wavy, ne-threaded.

(5) ukupholisha ubuso bensimbi

Ukupholisha kuyindlela yokuqeda yokulungisa ingaphezulu lengxenye. Ingathola kuphela indawo ebushelelezi ngaphandle kokuthuthukisa ukunemba komshini. Inani le-Ra lendawo epholishiwe lingafinyelela ku-1.6-0.008 um.

(6) Ukuqiniswa kwe-laser kwezindawo zensimbi

I-laser beam egxilile isetshenziselwa ukushisa ucezu lokusebenza ngokushesha bese lupholisa ngokushesha ucezu lokusebenza ukuthola indawo eqinile neqinisiwe. Ukuqinisa i-laser surface kunezinzuzo zokuguqulwa okuncane, ukusebenza okulula, nokuqinisa kwendawo.

2. I-Metal Surface Alloying Technology

Ngezindlela ezibonakalayo, izinto ezingeziwe zengezwa ku-matrix ukwenza ungqimba lwe-alloy. I-carburizing evamile kanye ne-nitriding kungokwale nqubo. Ibeka insimbi ne-ejenti engenayo egumbini elivaliwe elifanayo, ivule indawo yensimbi ngokufudumeza kwe-vacuum, futhi yenza ikhabhoni ne-nitrogen kungene ku-matrix yensimbi ngendlela yama-athomu ukuze kufezwe injongo yokuhlanganisa.

(1) Ukuba mnyama: Ifilimu ye-oxide emnyama noma eluhlaza okwesibhakabhaka ikhiqizwa ukuze ihlukanise umoya ekugqwaleni kwendawo yokusebenza.

(2) i-phosphating: Indlela yokwelapha yensimbi ye-electrochemical esetshenziselwa ukuvikela izinsimbi eziyisisekelo ngokufaka ama-phosphates ahlanzekile, angancibiliki emanzini phezu kwezinto zokusebenza ezicwiliswe kusixazululo se-phosphating.

Akekho kubo othinta isakhiwo sangaphakathi se-workpiece. Umehluko ukuthi insimbi emnyama yenza ucezu lokusebenza lucwebezele, kuyilapho i-phosphating ingeza ukujiya futhi ithuntuthe ingaphezulu le-workpiece. I-Phosphating ivikela kakhulu kunokumnyama. Mayelana nentengo, ukumnyama kuvame ukubiza kakhulu kune-phosphating.

(3) ubuchwepheshe bokuhlanganisa insimbi

Ukugqoka noma ukumboza kwenziwa phezu kwe-substrate ngezindlela ze-physicochemical. Isetshenziswa kabanzi kumathuluzi okusika i-carbide.

I-TiN coating kanye ne-TiCN enamathela endaweni yensimbi

Ama-microns ambalwa awugqinsi U-Tin Kumathuluzi okusika asika ithusi elithambile noma insimbi ethambile, okokusebenza kuvamise ukuba yigolide.

Izingubo ezimnyama ze-titanium nitride zivame ukusetshenziswa lapho i-coefficient yokungqubuzana incane kodwa ubulukhuni buyadingeka.

Okungenhla isingeniso sethu esifushane sokwelashwa kwendawo yensimbi. Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma nge-imeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
