Which metal coatings are applied using pulse electroplating?

Pulse electroplating can improve the uniformity of the coating. When plating precious metals, there are often minimum thickness requirements or resistance to corrosion specifications. At this point, the coating uniformity is good; to achieve the same minimum thickness, a smaller average coating thickness is required, which helps to save precious metals. Similarly, pulse electroplating can improve the uniformity of the coating and reduce its porosity. In this way, the average coating thickness required to achieve the same resistance level is reduced, which also helps to save precious metals. Due to the high value of precious metals, the benefits gained from conserving them can offset the cost of purchasing expensive pulse power supplies, and may even result in a profit. The power supply used for plating precious metals is also relatively small, and its price is more affordable, which facilitates its wider adoption. In turn, this has promoted research on pulsed electroplating of precious metals. On the contrary, for pulse power supplies used in galvanizing, it is a big question when the equipment investment will be recouped. 　　Therefore, pulse plating is often used when plating precious metals

Anything can be plated, but since pulse power supplies are relatively expensive, they are usually used for plating precious metals.
