Isantya esiphezulu se-Oxygen Fuel Ukutshiza iTungsten Carbide Powder Coating

Inkcazelo emfutshane:

Isantya esiphezulu se-Oxygen Fuel yokutshiza iCoating

Izinto eziluncedo kwezobuGcisa:

1,Imowudi ezintathu zokusebenza: ezoqoqosho, eziphezulu, eziphezulu

Ubume obufanayo bokugquma kunye nokuxinana okuphezulu (i-porosity ngaphantsi kwe-0.2%)

Ngaphantsi okanye akukho nanye idecarb (ayibonakali yi-XRD)

Ubulukhuni bokugquma obuphezulu (ngaphezu kwe-1600 HV0.3), iinguqulelo ezincinci kwiindawo zokugquma (50-60HV vs.150-200 HV ye-HVOF eqhelekileyo)

Okungakumbi ukumelana nokunxiba

Ukuqina okuphezulu kunye neempawu ezichasayo ze-cavitation

Giqinile kunye ne-50um engqingqwa ye-WC engaphantsi kwe-200MPa yegesi yenitrogen

Hizinga lokutshiza lobushushu:5-10um/pass

Ci-oating defect inokulungiswa kwindawo.

Iimveliso ze-Silicon carbide

Into mnas ukhetho olufanelekileyo lwezixhobo zobunjineli bobushushu obuphezulu.Ngenxa yeempawu ezibalaseleyo, iSilicon Carbide Ceramic ikwabonwa njengesixhobo sokutywina esisebenza ngoomatshini kangcono kunesinyithi, i-tungsten carbide, i-al2o3 ceramics njl njl

Indlela yokulungiselela i-tungsten carbide coating

I-tungsten carbide coating yamkela i-HVOF etshizwe nge-cobalt-based tungsten carbide alloy powder okanye i-nickel-based tungsten carbide alloy powder kunye ne-chromium-based tungsten carbide alloy powder.Ubunzima bunokufikelela kwi-HV1200 kunye nokumelana nobushushu obuphezulu be-850 degrees, ukwenzela ukuba iindawo zevalve zixhathise ukunxiba, ukubola kunye nokumelana nokushisa okuphezulu, i-anti-oxidation.Ukodlula ukubonwa kwezandla, ukutshiza, ukungcwatywa, ukucima kunye nokuthambisa, kunye nenkqubo, ukusebenza kakuhle kwemveliso kunokunyuswa ngamaxesha angaphezu kwama-2, iindleko zemveliso zinokucuthwa ngaphezulu kwe-50%, kwaye ubomi benkonzo bunokwandiswa ngamaxesha amaninzi. .

I-Microstructure ye-tungsten carbide coating:

Kwi-tungsten carbide coating, ii-athomu zekhabhoni zifakwe kwizithuba ze-tungsten zentsimbi ye-tungsten ngaphandle kokutshabalalisa i-lattice yentsimbi yokuqala, yenze isisombululo esiqinileyo se-interstitial, ngoko ikwabizwa ngokuba yi-interstitial (okanye ifakwe) ikhompawundi.I-tungsten carbide inokwenziwa ngokufudumeza umxube we-tungsten kunye nekhabhoni kwiqondo lokushisa eliphezulu.Ubukho be-hydrogen okanye i-hydrocarbons bunokukhawulezisa ukusabela.Ukuba i-oxygen-containing compound ye-tungsten isetyenziselwa ukulungiswa, imveliso kufuneka ifakwe i-vacuum iphathwe nge-1500 ° C ukususa i-carbon kunye ne-oxygen compounds.I-tungsten carbide kufuneka icutshungulwe ngomatshini kumaqondo aphezulu okushisa ukwenza izixhobo zokusika, izinto zokwakha ze-kilns, ii-jet injini, ii-turbines zegesi, imibhobho, njl.
