The difference between Nickel plating, galvanized, chrome plated


Galvanized appearance of silver white, for the iron substrate is anodic coating, a better electrochemical protection. Nickel appearance Silver yellow, for the iron substrate is a cathodic coating, and a higher void ratio, so a single anti-corrosion coating is not high. Chromium-plated decorative chrome and hard chrome appearance blue and white. The above three are only surface treatment technology, stainless steel is the fundamental material is different. Single from the appearance of nickel closest to the color of stainless steel. Chrome the most expensive, followed by nickel, zinc the cheapest, which also distinguish between hanging plating, barrel plating and so on. Hanging expensive, rolling plating.

Nickel, galvanized, chrome effect and difference

Galvanized appearance of silver white, for the iron substrate is anodic coating, a better electrochemical protection. Nickel appearance Silver yellow, for the iron substrate is a cathodic coating, and a higher void ratio, so a single anti-corrosion coating is not high. Chromium-plated decorative chrome and hard chrome appearance blue and white. The above three are only surface treatment technology, stainless steel is the fundamental material is different. Single from the appearance of nickel closest to the color of stainless steel.

Nickel, tin, zinc, chrome how to distinguish from the surface.

To distinguish from the color and surface gloss.

 1, galvanized. Galvanized sheet metal you must have seen, generally some sharp patterns of spots, relatively speaking, the surface of the most rough. A lot of stalls to write the White Iron Project, is galvanized sheet metal. For buckets, central air conditioning pipe.

2, nickel plating. Like a corner of the coin color, the surface of the most delicate, mirror effect.

 3, tin. Like a dollar coin color. The surface is delicate, if you see the tea or other tin box, which is silver, that is the true nature of tin. Generally used for tin.

 4, chrome. More yellow than tin. The same surface thickness and tin plating.

Chromium, nickel, galvanized difference, the use of the advantages and disadvantages.

Are used in the metal surface. Chromium is mainly to improve the surface hardness, beautiful, rust-proof. Chromium coatings have good chemical stability and do not act on bases, sulfides, nitric acid and most organic acids but are soluble in hydrohalic acids such as hydrochloric acid and hot sulfuric acid. Because of chromium does not change color, the use of long-term to maintain its reflectivity and superior to silver and nickel. The process is generally electroplating nickel plating is mainly wear-resistant, anti-corrosion, rust-proof, the general thickness is thin, the process of sub-plating and chemical two types of galvanized is mainly beautiful rust-proof. zn is a lively metal, with acid reaction, so poor corrosion resistance, but the cheapest in three addition silver plating, anodizing and so on.

Zinc plating, nickel plating, chrome plating and the difference between the respective use of the other chrome after zero.

I only know chrome and galvanized. Here to talk about the difference between the two: two different metal elements, galvanized surface is a bit cyan, chrome-plated surface is bright white (like stainless steel color), the general is mainly galvanized anti-corrosion. There are two kinds of chrome is a decorative, one is to increase the hardness and so on. Plating can be divided into three categories, namely, decorative plating (nickel-plated - chrome, gold and silver as the representative), protective electroforming (represented by galvanized) and functional electroplating One of the functional electroplating products that make use of electroplating.
