Chii chinonzi Cast Tungsten Carbide Powder

Cast tungsten carbide poda ine WC uye W2C eutectic chimiro chinoratidza kusviba kwegrey kutaridzika. Cast tungsten carbide poda inogadzirwa nemaitiro epamberi: simbi tungsten uye tungsten carbide hupfu zvinosanganiswa uye kurongedzerwa muchikepe chegraphite. Pamwe chete, vanopiswa muchoto chinonyunguduka pa2900 ° C uye vanobatwa kwenguva yakati kuti vawane casting block inosanganisira WC uye W2C eutectic phases ine saizi yezviyo ye1 ~ 3 μm.

Inoratidza kupfeka kwakatanhamara uye kupikisa kuramba, pamwe nekuomarara kwenzvimbo, pakupisa kwakanyanya. Saizi ye tungsten carbide particle inotangira kubva 0.038 mm kusvika 2.362 mm. Kuoma: 93.0 ~ 93.7 HRA; micro-kuoma: 2500 ~ 3000 kg / mm2; kuwanda: 16.5 g/cm3; kunyungudika: 2525°C.

Zvishandiso zveakakandirwa tungsten carbide grits

1. Pfeka pamusoro (kusapfeka-resistant) zvikamu uye machira. Zvikamu uye machira anosangana neshungu, abrasion, cavitation, uye kukukurwa kwechikamu senge maturusi ekucheka, maturusi ekukuya, maturusi ekurima, uye akaomeswa machira.

2. Diamond Tool Matrix. Yedu yakagadzirira-ku-infiltrate kana inopisa-press cast tungsten carbide poda inoshandiswa sehupfu hwematrix kubata uye kutsigira mudziyo wekucheka madhaimani. Mubati anobvumira kuratidzwa kwedhaimani kwakakwana kunodiwa kuti zvishandiswe zvakanaka zvematurusi.

Kugadzira Nzira dzekukandira tungsten carbide poda

1. Thermal Spray Process. Cast tungsten carbide girts inogona kuve yekupisa yakapfapfaidzwa kuti igadzire akaomesesa mabhanhire panzvimbo inoda kuwedzera kupfeka kuramba.

2. Kupinda. Cast tungsten carbide, coarse tungsten metal, kana tungsten carbide poda zvinopinzwa nesimbi inoyerera (e.g. copper-based alloy, bronze) kuita chikamu. Yedu yakakandwa tungsten carbide poda ine yakatanhamara yekupinda nekugona uye kupfeka hunhu hunobvumira vatengi vedu kugadzirisa mhinduro yemakwikwi yekuwedzera hupenyu hwesevhisi uye dhizaini inoshanduka.

3. Upfu Metallurgical (P/M). Cast tungsten carbide poda inotsikirirwa kuita zvikamu kuburikidza nekupisa nekutsikirira.

4. Plasma Transferred Arc (PTA) Welding. Nekuda kwekunakisisa weldability yecast tungsten carbide poda, inowanzoiswa kune zvinhu kuburikidza nePTA welding process.

5. Dip Coatings. Majasi akadai seanowanikwa mumaelectrode, maturusi ekuchera, uye zvikamu zvinosanganisirwa nekugadzirisa abrasive media zvakanyudzwa-yakaputirwa necast tungsten carbide inopa kupera kwepamusoro nekuoma kwakanyanya uye kusakara.
