Dacrotising on Brass

2001

I have come across a surface treatment process called "Dacrotising" on brass pipes used in the automobile radiators. I would like to know what is this process? What are its advantages vis-a-vis nickel-chrome plating?

I would be thankful to you if you can provide the relevant information.

Hi, Rajiv. You can find out more about Dacrotising from the supplier Metal Coatings International, but basically, Dacrotising is a process of coating a part with aluminum and zinc flakes. Beauty is in the eye of the beholder, but it's a functional coating rather than a coating that competes aesthetically with nickel-chrome.

Nickel-chrome is a barrier layer coating whereas Dacrotising is a sacrificial coating. So, if the part is subject to being seriously scratched, the Dacrotising is probably a better choice. If not, it depends on the environment, but either coating might last a decade or more. Good luck.
