Terminology yeHard Alloy(2)

Decarbonization

Mushure mekunyudza iyo simende carbide, iyo kabhoni yemukati haina kukwana.

Kana chigadzirwa chacho chaitwa decarbonized, nyama inoshanduka kubva paWC-Co kuenda kuW2CCo2 kana W3CCo3. Iyo yakanaka kabhoni yemukati ye tungsten carbide mune simende carbide (WC) ndeye 6.13% nehuremu. Kana iyo kabhoni yemukati yakadzikira, pachave neinodudzwa kabhoni-inoshomeka chimiro muchigadzirwa. Decarburization inoderedza zvakanyanya simba re tungsten carbide simende uye inoita kuti iwedzere brittle.

Carburization

Inoreva iyo yakawandisa kabhoni yemukati mushure mekunyudza iyo simende carbide. Iyo yakanaka kabhoni yemukati ye tungsten carbide mune simende carbide (WC) ndeye 6.13% nehuremu. Kana iyo kabhoni yemukati yakawandisa, yakadanwa carburized chimiro ichaonekwa muchigadzirwa. Pachave neakakosha yakawandisa yemahara kabhoni muchigadzirwa. Kabhoni yemahara inoderedza zvakanyanya simba uye kupfeka kuramba kwe tungsten carbide. C-mhando pores muchikamu-kuonekwa inoratidza chiyero che carburization.

Kumanikidza

Coercive force isimba remagineti rasara rinoyerwa nekuita magineti mu carbide yakasimwa kusvika panzvimbo yakaguta yobva yaita magineti. Pane hukama hwakananga pakati peavhareji saizi ye simende carbide chikamu uye kumanikidza. Iyo yakatsetseka yeavhareji saizi yechikamu chemagnetized, inokwirisa iyo coercivity kukosha.

Magnetic saturation

Cobalt (Co) ine magineti, nepo tungsten carbide (WC), titanium carbide (TiC), uye tantalum carbide (TaC) isiri-magineti. Naizvozvo, nekutanga kuyera iyo magineti saturation kukosha kwecobalt muchinhu uye wozoienzanisa nehukoshi hunoenderana hweyakachena cobalt sampu, sezvo iyo magineti saturation inobatwa nealloying element, iyo alloying level yecobalt-yakasungwa chikamu inogona kuwanikwa. . Chero shanduko muchikamu chebinder inogona kuyerwa. Sezvo kabhoni ichiita basa rakakosha mukudzora kuumbwa, nzira iyi inogona kushandiswa kuona kutsauka kubva kune yakanaka kabhoni yemukati. Yakaderera magineti saturation kukosha inoratidza yakaderera kabhoni yemukati uye mukana we decarburization. High magnetic saturation values ​​inoratidza kuvapo kwemahara kabhoni uye carburization.

Cobalt Dziva

Mushure mekupisa simbi cobalt (Co) binder uye tungsten carbide, yakawandisa cobalt inogona kuumbwa, inova chiitiko chinozivikanwa se "cobalt pooling". Izvi zvinonyanya kuitika nekuti panguva yeHIP (Pressure Sintering) maitiro, tembiricha yekupisa yakadzikira uye zvinhu zvinoumba kusakwana density, kana ma pores anozadzwa necobalt. Sarudza saizi yedziva recobalt nekuenzanisa mifananidzo yemetallographic. Kuvapo kwedziva recobalt mune simende carbide kunokanganisa kupfeka kuramba uye kusimba kwezvinhu.

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
