[0045] A corrosion-resistant TiO 2 -ZrO 2 The liquid phase deposition preparation method of coating comprises the following steps:
[0046] 1) Take 200 mL of distilled water, divide it into four parts, 20 mL, 80 mL, 70 mL and 30 mL, and dissolve 4.04 g (NH 4 ) 2 TiF 6 (mass content 98%), 2.49 gH 3 BO 3 (mass content 99.5%), 5.80 gZr(SO 4 ) 2 4H 2 O (mass content 98%) and 11.18 g (NH 4 ) 2 S 2 o 8 (The mass content is 98%). get (NH 4 ) 2 TiF 6 Aqueous solution, H 3 BO 3 Aqueous solution, Zr(SO 4 ) 2 aqueous solution and (NH 4 ) 2 S 2 o 8 Aqueous solution; the resulting solution was left to stand and filtered to remove particles visible to the naked eye, and then used.
[0047] 2) will (NH 4 ) 2 TiF 6 aqueous solution and H 3 BO 3 After the aqueous solution was mixed, it was filtered again to obtain a clear solution A.
[0048] 3) Zr(SO 4 ) 2 aqueous solution and (NH 4 ) 2 S 2 o 8 The aqueous solutions were mixed to give clear solution B.
