Zɛnki-Aluminiyɔmu sɔgɔlenw ka baarakɛcogo sariya

Gɛlɛya ni sɛgɛnba-Matirisi min bɛ se ka kɛlɛ: Zɛnki-aluminiyɔmu sɔgɔlen bɛ ni aliminiyɔmu 27% ɲɔgɔn ye. Solidification kɔfɛ, aliminiyɔmu-zinc intermetallic compound reinforcement phases caman bɛ sɔrɔ, o bɛ gɛlɛya ni sɔgɔli fanga ɲɛ kosɛbɛ (fo ka se 400–430 MPa ma), o bɛ kɛ sababu ye ka mikroskɔpi dɛmɛnan sabatilen di sɔgɔsɔgɔninjɛ waati, ani ka dɔ bɔ sɛgɛn na.

Yɛrɛ-Tulukɛcogo:
Grafite-bushings (busi) minnu bɛ don grafite la, grafite saniyalenba- bɛ don matiriyali sanfɛyɔrɔw la (a bɛ 20%–30% datugu sɔgɔsɔgɔninjɛ yɔrɔ la). Fɔɔnɔ waati la, grafite bɛ wuli ka taa furuɲɔgɔnma-yɔrɔ sanfɛla la funteni ni masin-wale kɔrɔ, ka tuluma-filimu dɔ dilan min bɛ to senna, ka sɔgɔsɔgɔninjɛ hakɛ dɔgɔya ka se 0,06–0,12 ma, ka tulu-tulu sɔrɔ min tɛ tulu bɔ.
