1. Qalabka taayirka duubista ee isku dhafan ee labaad ee Chromium oo bir ah oo tayo sare leh
Gacanta birta chromium ee sare leh ee dhoobada ah waxaa laga sameeyay bir chromium oo sare leh oo ah walxo matrix ah, iyada oo loo marayo hab gaar ah, bir chromium oo sare leh iyo walxo dhoobo malab ah oo malab ah oo isku dhafan, walxaha dhoobada ah ee dhoobada ah ee ZTA, ka dibna iyada oo loo marayo habka shubista ciidda, isku-darka dhoobada ee birta chromium ee sare leh iyo qaabaynta birta ductile ee labaad. Halabuurka kiimikada ee walaxda birta chromium ee sare leh waxaa lagu muujiyay Shaxda 1 ee hoose.
Shaxda 1: Halabuurka kiimikada ee duubista birta chromium-ka ee sare (wt%)
| Alaab | C | Si | Mn | S | P | Cr |
| Taayirada duubista ee isku-dhafka dhoobada ah ee birta chromium sare leh | 2.8-3.2 | 0.5-1.0 | 0.5-1.2 | ≤0.05 | ≤0.05 | 20-26 |
| Birta Ductile | 3.2-3.9 | 2.5-2.7 | 0.3~0.5 | ≤0.04 | ≤0.04 |
2. Hantida farsamada
Taayirka isku-dhafka dhoobada ah ee birta chromium ee sare waa qaab-dhismeed isku-dhafan oo labaad oo ka kooban birta chromium ee sare, walxaha dhoobada ah ee ZTA iyo birta ductile, taas oo ka dhigaysa gacanta roll-ka isku-dhafka dhoobada ah ma aha oo kaliya inay leedahay xoog iyo adkaansho sare, laakiin sidoo kale waxay leedahay adkeysi sare, taasoo hubinaysa iska caabbinta xirashada iyo badbaadada gacanta roll-ka. Adkaysiga walxaha dhoobada ah ee ZTA wuxuu ka sarreeyaa HV2100, halka adkaysiga birta chromium ee sare ee M7C3 carbide uu ka sarreeyaa HV1400, iyo adkaysiga matrix-ka birta chromium ee sare wuxuu ka sarreeyaa HV750, sidaas darteed, iyadoo xaaladdu tahay mid cadaadis sare leh oo laba jir ah oo la xoqo, sababtoo ah farqiga u dhexeeya agabka, cimriga adeegga ee gacanta roll-ka isku-dhafka dhoobada ah waa 1.5-3 jeer ka badan gacanta caadiga ah ee chromium ee sare ee birta roll-ka. Astaamaha birta chromium ee sare iyo birta ductile waxaa lagu muujiyay Shaxda 2 ee hoose.
Shaxda 2: Hantida Farsamada
| Alaab | Xoogga jiidista /Mp | Adkaanta Saamaynta J/cm2 | Adkaanta/HRC | Heerka Kordhinta (%) |
| Chrome Sare | ≥800 | ≥4 | ≥60 | --- |
| Birta Ductile | 500~650 | ---- | 147~241(HB) | 4~10 |
3. Naqshadeynta qaab-dhismeedka taayirka duubista ee isku-dhafka ah ee birta chromium-ka ee sare leh
Naqshadeynta qaab-dhismeedka ee gacanta birta chromium ee birta chromium ee sare leh waxaa lagu muujiyay Jaantuska 1 iyo Jaantuska 2 ee hoose. Aagga malabka cas waa aagga qaybinta walxaha dhoobada ee u adkaysta xirashada ZTA. Walxaha dhoobada ah waxaa lagu qaybiyaa matrix-ka dahaarka chromium ee sare leh qaab-dhismeedka malabka, lakabka dhoobada ahna wuxuu daboolayaa aagga xirashada shaqada ee gacanta duubista oo dhan. Aagga cagaaran ee ka baxsan lakabka dhoobada waa bir chromium oo sare leh, aagga buluuggana waa bir ductile ah.
