Adwumayɛ Nnyinasosɛm a ɛfa Zinc-Aluminum Alloy Bushings ho

High Hardness and Wear-Resistant Matrix: Zinc-aluminum aduru no kura bɛyɛ 27% aluminium. Afei solidification, aluminum-zinc intermetallic compound reinforcement phases dodoɔ bi na ɛba, na ɛma hardness ne tensile ahoɔden tu mpɔn kɛseɛ (ɛkɔ 400–430 MPa), ɛma microscopic support structure a ɛyɛ den wɔ friction mu, na ɛtew wear so.

Ankasa-Srade Adwinnade:
Wɔ graphite-embedded bushings mu no, wɔde graphite a ɛho tew kɛse -ahyɛ matrix no ani pores mu (ɛkata 20%–30% wɔ friction area no so). Wɔ friction mu no, graphite dan kɔ mating shaft no ani wɔ ɔhyew ne mfiri adeyɛ ase, yɛ srade film a ɛkɔ so, na ɛtew friction coefficient so kɔ 0.06–0.12, na ɛma oil-free lubrication.
