Coating & Sintering Process – Etape decisive ka ɲɛsin kelenya ma

1. Coating fɛɛrɛ sumalen

Fɛɛrɛ ɲuman minnu bɛ kɛ iziniw kɔnɔ : Taabolo faralen ɲɔgɔn kan – dip coating + blade coating – a bɛ tali kɛ kosɛbɛ. O bɛ dip coating ka jisuma bɛɛ lajɛlen ɲuman fara ɲɔgɔn kan ni blade coating ka surface flatness outstanding ye, ka fibre encapsulation fanga ni surface precision balansi.

2. Jalen & Sintering cogoyaw

Dip + blade faralen ɲɔgɔn kan taabolo ye izini sariya ye PTFE finiw na minnu ka funteni ka bon. Nin ye kun ye : dip coating dɔrɔn bɛ ‘meniscus effect’ (meniscus effect) lase – finimugu bɛ bonya a dawolow la, ka fin a cɛmancɛ la ka a sababu kɛ emulsiɔn sanfɛla tension ye ni fini bɛ bɔ baarakɛyɔrɔ la.
