example 1

[0027] will be relative to 30-40nm α-Al 2 o 3 Dosage of 2% Mgcl 2 α-Al with primary grain size of 30-40nm 2 o 3 Mix ball mill for 6 hours, invert phase at 1300 degrees, make α-Al 2 o 3 Crystal > 99%, the primary grain size is 60-80nm. Then the above powder is mixed according to the ratio of powder: water: maleic acid: o-hydroxybenzenesulfonic acid 45:53:1:1, and dispersed in a rolling ball mill for 80 hours to obtain the electroplating slurry. This slurry is suitable for composite electroplating characterized by corrosion resistance.

example 2

[0029] will be relative to 30-40nm α-Al 2 o 3 The amount of 5% La(NO 3 ) 3 α-Al with primary grain size of 30-40nm 2 o 3 Mix ball mill for 10h, invert phase at 1200°C, make α-Al 2 o 3 Crystal > 99%, the primary grain size is 60-80nm. Then the above powder was mixed according to the ratio of powder: water: maleic acid: triethylbenzyl ammonium chloride 40:57:1:1, and dispersed in a rolling ball mill for 90 hours to obtain the electroplating slurry. This slurry is suitable for composite electroplating characterized by high wear resistance.

example 3

[0031] will be relative to 30-40nm α-Al 2 o 3 The amount of 1% NiCl 2 α-Al with primary grain size of 30-40nm 2 o 3 Mix ball mill for 8h, invert phase at 1500°C, make α-Al 2 o 3 Crystal > 99%, the primary grain size is 60-80nm. Then the above-mentioned powder is mixed by powder: water: maleic acid: o-hydroxybenzenesulfonic acid ratio of 40:58:1:1, and dispersed in a rolling ball mill for 70 hours to obtain nickel-based composite electroplating. slurry.

[0032] The following is an example of using the slurry of the present invention to obtain a nanocomposite electroplating layer:

Abstract

A nano-class composite slurry for electroplating is prepared through mixing alpha-Al2O3 with the oxide is alkali-earth metal and / or transition metal and / or rare-earth metal by ball grinding for 6-10 hr transferring phase at 1200-1500 deg.C, proportionally mixing powder, water and cationic surfactant, and dispersing in ball grinder for 60-100 hr. It can be added to traditional plating liquid to obtain decorative-protective-functional plated layer.

Description

technical field [0001] The invention belongs to the technical field of chemical surface treatment, and specifically relates to a method for various metals and alloys: nickel, zinc, copper, iron, chromium, cobalt, gold, silver, cadmium, tin, lead and other metals and nickel-cobalt alloys, nickel Slurry for nano-composite electroplating, nano-electroless plating and nano-electroforming of iron alloys, lead-tin alloys, nickel-phosphorus alloys, iron-phosphorus, and nickel-boron alloys. technical background [0002] In the development of modern electroplating technology, composite electroplating is the most active part. Since it was successfully researched in the 1930s and put into production in the 1960s, it has developed extremely rapidly and its application fields have continued to expand. In the same period, in terms of decorative electroplating, in order to obtain a highly corrosion-resistant coating, Ambit Corporation of the United States invented multi-layer electroplatin...
