Phosphating adalah proses perlakuan
terhadap logam (besi, galvanized atau aluminium) menggunakan asam phosphate dan
senyawa lainnya dimana permukaan logam bereaksi secara kimia dengan media asam
phosphate tersebut membentuk lapisan kristal phosphate yang tidak larut yang
melindungi permukaan logam secara keseluruhan.
Mengapa proses phosphating dan metal pre-treatment penting untuk dilakukan ?
a. Membersihkan metal/ logam
(Degreasing)
b. Persiapan untuk proses pengecatan
c. Mengurangi reaksi metal/ cat
d. Meningkatkan ketahanan terhadap korosi
e. Meningkatkan ketahanan terhadap Blister
Faktor-faktor yang mempengaruhi Hasil Phosphating :
-Metode cleaning yang digunakan
-Penggunaan surface conditioning
-Metode aplikasi yang digunakan (Spray atau
dipping)
-Suhu, konsentrasi dan waktu
-Modifikasi
komposisi larutan
a. Spray (Penyemprotan, dengan bantuan mekanik ke arah
benda kerja).
