Iyo poda inogadzirwa neagglomeration uye sintering process kuti iite ingangoita spherical particles ine yakanaka fluidity. Simba rayo rekubatanidza rinopfuura 70MPa uye kugona kwekuisa kuri pakati pe30% ne45%, kuratidza kuita kwakanaka kwekupfapfaidza. Hupfu hune huwandu hwakawanda hwe2.5g/cm³, chidimbu chehukuru hwe12-45 microns, uye kuyerera kwemasekonzi makumi matatu / 50 magiramu, iyo inokodzera nzira dzakasiyana dzekupfapfaidza dzakadai seHVAF (high velocity air flame spraying), HVOF (high tembiricha uye high pressure flame spraying) uye APS (air plasma). Iyo yakanyanya tembiricha yekushanda yejasi inogona kusvika 800 ℃, uye kuomarara kwemhando iHV900-1150, kuve nechokwadi chekugadzikana kwayo uye kupfeka kusagadzikana munzvimbo dzakanyanya tembiricha.

Product Performance

Iyo yekuputira yeDG.Cr3C2-25NiCr poda ine zvakawanda zvakanakisa zvivakwa. Kutanga, iyo anti-oxidation mhedzisiro yakakosha uye inogona kunyatso kurwisa oxidation corrosion munzvimbo dzekushisa kwepamusoro. Chechipiri, iyo yekupfekedza inogona kumira kutsvedza kupfeka, abrasive kupfeka, kuvhuvhuta uye corrosive kupfeka, uye yakakodzera kune akasiyana hutsinye mamiriro ekushanda. Uye zvakare, iyo yekupfekedza inopesana nekupisa kupisa gasi corrosion, yakanyanya tembiricha yemvura corrosion uye yakanyanya tembiricha yakasimba corrosion, ichivimbisa kuvimbika kwayo pasi pemamiriro akanyanya.

Nzvimbo dzekushandisa

Pamusana pekushanda kwayo kwakanakisisa, DG.Cr3C2-25NiCr powder inoshandiswa zvakanyanya mundima dzakawanda. Chekutanga, kumucheto kwemberi kweinjini dzendege, kupfekedza kunogona kuchengetedza zvinobudirira zvikamu zveinjini uye kuwedzera hupenyu hwavo hwesevhisi. Kechipiri, pamadziro emukati meiyo boiler mune inodziya magetsi chirimwa, iyo yekuputira inogona kuramba tembiricha yepamusoro uye ngura kuti ive nechokwadi chekushanda kwakachengeteka kwemidziyo. Mukuwedzera, zvikamu zvakakosha zvakadai sema turbine blades uye high-pressure valves zvinowanzoputirwa nemucheka uyu kuti uvandudze kusapfeka kwavo uye kusagadzikana kwekuora.

Spraying process parameters

Mukuita kupfapfaidza, zvakakosha kwazvo kusarudza yakakodzera pfuti yekupfapfaidza uye maitiro paramita. Tichitora Lijia parafini supersonic spray pfuti semuenzaniso, hupfu hwayo hunosvika 15-45 microns, saizi yedhiramu inches 8 inches, parafini inoshandiswa 25L/h, iyo oxygen yekuyerera iri 900L/min, iyo inotakura gasi inoyerera i7.5L/min, iyo poda yekupfapfaidza iri 5. 320-360mm. Aya ma parameter ndeekutarisa chete. Mukushanda chaiko, dzinoda kugadziridzwa zvinoenderana neyakasiyana midziyo kuti iwane yakanakisa yekupfapfaidza maitiro.

mukupedzisa

DG.Cr3C2-25NiCr thermal spray poda yave imwe yezvinhu zvakakosha muindasitiri yemazuva ano nekuda kwekunaka kwayo kemikari uye zvimiro zvemuviri. Kushandiswa kwayo mukupisa kwakanyanya uye nharaunda yekuora kwakakwira kunoratidza basa rakakosha reiyo tekinoroji yekupfapfaidza tekinoroji mukuvandudza mashandiro emidziyo uye nekuwedzera hupenyu hwebasa. Nekuenderera mberi kwekufambira mberi kwehunyanzvi, nzvimbo yekushandisa yeDG.Cr3C2-25NiCr hupfu ichawedzerwazve, ichipa vimbiso yakasimba yekusimudzira maindasitiri akasiyana.
