Maxay yihiin ulaha isku dhafan ee tungsten carbide?

Usha isku dhafan ee Tungsten carbide waxay ka samaysan tahay talooyinka carbide sibidhka iyo Ni/Ag(Cu)daawaha. Talooyinka carbide had iyo jeer waa tungsten carbide la jajabiyey grits, xidhashada carbide xidhashada, sida xidhashada qaab xiddigaha carbide, gashto qaabka Ahraamta carbide, gelisa qaabka shark, iyo wixii la mid ah. Mararka qaarkood, talooyinka carbide waxay noqon karaan budada carbide tungsten. Doorashada dhaqaalaha waa tungsten carbide grits la jajabiyey. Haddii aad rabto in aad ka sii adkaysato kaarbiid grits, gashad carbide ayaa ka fiican. Si kastaba ha ahaatee, kaarbiide sibidhka/la jajabiyey oo leh gees fiiqan ayaa leh iska caabin aad u fiican iyo awood goynta sidoo kale.

Adaggu waa 89-91 HRA, binder binder waa Ni iyo aluminium naxaas ah, xooggu wuxuu gaari karaa ilaa 690MPa, qallafsanaanta HB≥160.

Si kooban, inta badan ulaha isku dhafan ee la sameeyay iyadoo la adeegsanayo miraha Tungsten Carbide oo la shiiday oo ku xidhan matrix nikkel bronze ah, (Cu 50 Zn 40 Ni 10) oo leh dhibic dhalaalaysa (870°C).

Waa maxay sababta loo isticmaalo tungsten carbide grits sida walxaha ugu muhiimsan

Dhammaanteen waan ognahay carbide tungsten wuxuu leeyahay qallafsanaan sare,Carbide Tungsten wuxuu leeyahay waxqabad wanaagsan oo goynta Birta.Tungsten carbide grits waxay leeyihiin sifooyin iska caabin ah. Tungsten carbide grits waxay ilaalin kartaa dusha sare ee qalabka ay ku xiran tahay xirashada nabarrada. Tungsten carbide talooyin raisexawaarihii qodista iyo goynta,ilaalinta cabbirka buuxa ee xasiliyayaasha, hagta masaxadaha fadhiga muhiimka ah, iyo aaladaha kale ee godka hoostiisa laga soo dejiyo.

Cabbirrada hadhuudhka ee grits carbide:

1/8-1/16 in. (3.2-1.6 mm)

3/16-1/8 in. (4.8-3.2 mm)

1/4-3/16 in. (6.3-4.8 mm)

3/8-5/16 in. (9.5-7.9 mm)

5/16-1/4 inji (7.9 -6.3 mm)

3/8-1/4 inji (9.5-6.3 mm)

1/2-5/16 in. (12.7-7.9 mm)

Darajooyinka ulaha isku dhafan

Laba darajo oo waaweyn waxay ku xiran yihiin Saamiga kala duwan ee tungsten carbide grits

1. Darajada goynta:70% carbide tungsten + 30% xidhe

2. Xiro darajada:60% carbide tungsten + 40% xidhe

Waxaad dooran kartaa darajooyin kala duwan iyadoo ku xiran codsigaaga.
