自动刷镀工艺英文参考文献和翻译 Abstract
An automatic brush plating system was developed to eliminate the disadvantages resulting from the operator in conventional brush plating.
With this system, Ni/nano-Al2O3 composite coatings on 45 steel substrates were prepared from an electrolyte containing 20 g/l nano-Al2O3
particles. For comparison, Ni/nano-Al2O3 composite coatings were also prepared manually. Microstructure, surface morphology, microhardness,
modulus and wear resistance of two Ni–matrix composite coatings were investigated comparatively. Our present study shows that coating
prepared automatically is much more dense, smooth, and uniform than that prepared manually. The former exhibits better mechanical and anti-
wear properties than the latter.

1. Introduction
Charles Dalloz and Georges Icxi designed the brush plating
process in 1937 [1].本文来自六)维,论(文'网,毕业论文 www.lwfree.cn 加7位QQ324_9114找源文 An important milestone in the development
of brush plating process was that the first North American
commercial specification was issued for brush plating in
1956, thus formally recognizing brush plating process as a
viable electroplating process. Today, brush plating has gained
widespread applications in engineering, especially for repair
and maintenance.
Brush plating, also known as selective plating, or swab
plating, is a very useful and portable method of contact plating.
In its simplest form, the brush plating process resembles paint-
ing. Brush plating equipment includes power packs, solutions,
plating tools, anode covers, and auxiliary equipment. The
power pack has two leads. One is connected to the plating
tool and the other is connected to the workpiece to be plated.
The anode is covered with an absorbent material which holds
the solution. The operator dips the plating tool in the solution
and then brushes it against the surface of the workpiece that is
to be finished. When the anode touches the work surface a
circuit is formed and an electrodeposit is produced. Plating2991
