黄金和镀金之间的差异|比较类似术语之间的差异

Thekey differencebetween gold and gold plated items is thatwe call pure gold or goldalloysas gold whereas gold plated means that a coating of gold is applied on the surface of another metal.

黄金是一种金属人知道因为旧t times. It has become a precious metal due to its brightness, softness,腐蚀resistance in most chemical natures,ductilityand scarcity. Many people confuse the gold with gold plated items. Plated gold is a coating of gold which is fused on another metal. The price of gold and the need to imitate gold make the need for gold-plated items. Jewellery is the most common items made of gold.

What is Gold?

黄金是一种柔软，可延展和延性金属。由于这种金属的柔软度，我们可以将其与其他金属（如铜）合金。在那里，我们可以在卡拉特（Karat）用黄金合金中给予黄金百分比。24K（24卡拉斯）金是纯金（未与任何其他化学元件合金）。22k黄金具有22个黄金的部分，而重量则有另一个合金元素的两个部分。因此，我们表达黄金的内容和24的合金元素。通常，我们将所有合金称为黄金。

此外，我们需要在其上盖上该物品的黄金含量。但是，由于其柔软度，24K黄金不适合使用实用的日常使用。尽管纯金的耐腐蚀性非常出色，金合金中黄金的含量降低，但对腐蚀的耐药性会降低。因此，黄金比例高的黄金耐用性更高。

这种金属是一种脆弱的金属，我们可以从中制作出非常薄的碎片，例如金色的叶子。由于黄金是具有高电导率的金属之一，因此它可用于在电子行业生产电路。但是，由于黄金的花费，黄金物品已成为黄金物品的一种选择。

什么是镀金？

镀金意味着在另一种金属的表面上施加金涂层。要应用涂层，我们至少需要10k黄金。对于这种黄金镀层过程的最常见技术是电镀。在那里，我们将钾 - 黄金氰化物溶液作为用于电镀的浴缸。除此之外，我们还可以使用电镀和浸入电镀技术。

The plating of this metal wears off quickly depending on the usage. Gold plated items are also prone to corrosion due to the base metals beneath the coating. Moreover, the metals under the coating of jewellery can cause allergies to some people.

Furthermore, the durability of gold plated items depends on the following factors:

黄金层的厚度
the gold content of the gold layer
the quality of the metal that we use beneath the gold layer

Apart from that, we can distinguish gold from gold plated items by carrying out appropriate tests. Gold and gold plated items are difficult to differentiate because of their same appearance. But we can identify them with tests. Therefore, we can use these available tests to identify whether the items are fake or not in the case of jewellery. However, people use gold plated items widely as a substitute for gold.

镀金和黄金有什么区别？

黄金是一种柔软，可延展和延性金属。镀金意味着在另一种金属的表面上施加金涂层。Therefore, the key difference between gold and gold plated items is that we call pure gold or gold alloys as gold whereas gold plated means that a coating of gold is applied on the surface of another metal. Another important difference between gold and gold plated metals is that the durability of gold is higher than that of gold plated metals. Moreover, gold is more expensive than gold plated metals.

概括– Gold vs Gold Plated

Gold is a highly expensive metal. Therefore, as a substitution, we can use gold plated items rather than using items made of pure gold. The key difference between gold and gold plated items is that we call pure gold or gold alloys as gold whereas gold plated means that a coating of gold is applied on the surface of another metal.
