He aha nā ʻanuʻu o ka pauka metallurgy?

Hoʻomaʻamaʻa ʻili ʻana i ka lepo metallurgy(ma hope o ka mālama ʻana i ka wela, ka ʻoki ʻana a me ka hoʻoliʻi ʻana)
He kūpono no ka hoʻoheheʻe ʻia ʻana o ka pauka ferrous a me ke kila kila pauka metallurgy

1. Wehe i ka aila a wehe i ka adhesion ma ke kiʻekiʻe wela, no laila e kahe ka aila a me nā adhesives i ke kino mai nā pores ili a carbonize i kahi mahana o 200-220 ° c no 1 hola.
2. E hoʻopaʻa i ka lua a hoʻolapalapa i ka wai hoʻolapalapa o ka wai deionized no 5 mau minuke a i ʻole he zinc stearate no 20 mau minuke.
3. E ʻōwili a holoi me ka ʻaila a me ka wai (ultrasonic).
4. E hoʻomoʻa i ka solution passivation MJ0045 i ka mahana lumi a i ʻole me ka hoʻomehana kūpono no 10-15 mau minuke.
5. ʻO ka holoi ʻana a me ka hoʻomaloʻo ʻana (2-3 mau makahiki ka pale ʻana i ka ʻeleʻele o ka metala pauka i hoʻokumu ʻia i ka hao, ka pale ʻana o ka paʻakai paʻakai o ka pauka kila kila no nā hola he 48)
6. E like me nā koi hiki ke hoʻokomo i loko o kaʻaila (passivated surface a laila hoʻokomo i kaʻaila), e hana i ka spraying.Electrophoresis a me ka electroplating.
