Lebelo le Phahameng la Oksijene Fuel Ho Fafatsa Tungsten Carbide Powder Coating

Tlhaloso e Khutšoanyane:

Lebelo le phahameng la Oxygen Fuel Spraying Coating

Melemo ea Tekheniki:

1, Mekhoa e meraro ea ho sebetsa: moruo, Phahameng, Ultra

Mohaho o ts'oanang oa ho roala ka mokhoa o ts'oanang le sekhahla se phahameng (porosity ka tlase ho0.2%)

Decarb e nyane kapa e se nang letho (e sa bonahaleng ke XRD)

Ho thatafala hoa holimo (ho feta 1600 HV0.3), liphapang tse fokolang ho ea ka libaka (50-60HV vs.150-200 HV bakeng sa HVOF e tloaelehileng)

Ho se mamelle ho eketsehileng

Matla a phahameng le thepa e hanyetsanang le cavitation

Ge tiile ka 50um e teteaneng ea WC tlas'a 200MPa ea khase ea naetrojene

Hsekhahla sa ho fafatsa ka matla: 5-10um/pass

Cbofokoli ba ho oting bo ka lokisoa sebakeng sa heno.

Lihlahisoa tsa silicon carbide

Ke is khetho e nepahetseng bakeng sa lisebelisoa tsa boenjiniere tse phahameng tsa mocheso.Ka lebaka la thepa e hlahelletseng, Silicon Carbide Ceramic e boetse e tsejoa e le thepa ea ho tiisa ka mechine e molemo ho feta tšepe, tungsten carbide, al2o3 ceramics joalo-joalo Ho feta moo, e boetse e na le melemo ea thepa ea ho itlotsa le coefficient e tlaase ea likhohlano.

Mokhoa oa ho itokisa oa ho roala ka tungsten carbide

Thepa ea tungsten carbide e nka HVOF e fafalitsoeng ka cobalt e thehiloeng ho tungsten carbide alloy powder kapa nickel-based tungsten carbide alloy powder le chromium-based tungsten carbide alloy powder.Boima bo ka fihla HV1200 le ho hanyetsa mocheso o phahameng oa likhato tse 850, e le hore likarolo tsa valve li hanyetsane le ho apara, ho senya le ho hanyetsa mocheso o phahameng, anti-oxidation.Ho feta ts'ebetso ea matsoho, chromizing, carburizing, quenching le tempering, le ts'ebetso, katleho ea tlhahiso e ka eketsoa ka makhetlo a fetang 2, theko ea tlhahiso e ka fokotseha ka ho feta 50%, 'me bophelo ba tšebeletso bo ka eketsoa ka makhetlo a mangata. .
