Nei tungsten carbide ndiyo yakanakira chishandiso zvinhu

Tungsten carbide(WC) musanganiswa unoumbwa nerefractory metal tungsten uye isiri-metallic kabhoni, ine hunhu hwehupamhi hwepamusoro, yakanyanya kunyungudika, simba repamusoro, kuoma kwepamusoro, kupisa kwekushisa, kusaita ngura, kusapfeka uye kunaka kwemagetsi nekupisa. , saka yakanakira carbide chishandiso zvinhu.

Nekudaro, nekuda kwedambudziko rehunyoro uye kusasimba kusimba kweiyo nyore WC poda, zvinowanzodikanwa kuwedzera huwandu hwakakodzera hwebinder senge cobalt (Co), nickel (Ni), chromium (Cr), molybdenum (Mo), titanium ( Ti), mhangura (Cu) uye zvimwe zvinhu kana uchigadzira yakakwirira yakazara kuita carbide maturusi.

Kunyanya, neWC poda sechikamu chakaoma uye Co sechikamu chebinder chakanyanya kukodzera kucheka maturusi.Iyo ine yakanaka yekupisa conductivity, iyo yakanaka yekucheka kupisa kupisa kubva pamuromo wechishandiso, kuderedza tembiricha yekupisa uye kudzivirira kupisa uye kupfava kwechishandiso tip;ine yakakwira flexural simba uye kukanganisa kuoma, izvo zvinogona kunyatso kudzikisa mukana wekucheka kana uchicheka;ine yakanakisa kucheka kupikisa (kure kupfuura simbi yakakwira), uye inogona kukuya inopinza.

simende carbide bladeneWC poda sechikamu chakaoma uye Ni sechikamu chekubatanidza chakanyatsokodzera zvikamu zvinodzivirira kuora.Kupokana kwayo necorrosion kwakasimba kupfuura yetungsten uye cobalt carbide maturusi, zvichiita kuti ive yakakodzera kushandisirwa munzvimbo dzine akasiyana corrosive media.Pamusoro pezvo, WC-Ni cemented carbide seals inokodzerawo kunyorera mukupisa kwakadzika, tembiricha yepamusoro, vacuum uye yakanyanya kudzvanywa.

Iyo inoumbwa neWC, TiC uye Co ine hunhu hwekuoma kwakakwirira, kunaka kwekudzivirira kupisa, kusimba kwakanyanya kwekumanikidza, yakanaka oxidation kuramba, kushata kwemafuta ekupisa uye zvichingodaro, izvo zvakakodzera kugadzira simbi.

Zvinofanira kucherechedzwa kuti chaiwo muviri zviratidzo zvehard alloyichachinja nechiyero chakasiyana chemidziyo.Kana akaturikidzana kana akawanda akaturikidzana e carbide, carbide uye mamwe maomesheni akaomarara akapfapfaidzwa pamusoro peiyo yakaoma alloy, iyo yakakwira kupfeka kuramba uye kuomarara kweiyo alloy kunowedzera kuenderana, saka inonyanya kukodzera kucheka kwekukurumidza. .
