Titanium Nitride brake caliper coating

SkyZ · 03-28-2010, 07:37 PM

hey guys, i had this crazy idea half a year ago of wanting my brake calipers to be shiny gold. I dont know how i got to this but i started searching up coating materials and stumbled upon titanium nitride which is used on drill bits, shines in a similar spectrum to gold (the material) and very heat + scratch resistant (it IS on drill bits).

i didnt want to simply paint it so i thought of ideas. anyways i thot it was an interesting idea and i just wanna for everyone's 2 cents on this.

unfortunately there is a problem with this. As a machinist I am EXTREMELY familiar with TiN coatings and for your sake stop thinking of it as a coating. It is applied as a heat treatment to steel and cobalt(the main binding material for carbide tools) and requires heating the part to extremely high temperatures. FYI steel parts are coated at temperatures just below the transformation temperature of steel which is usually right around 1200 degrees F.

Edit: also it is an excellent thermal barrier so all the heat from your brakes would be trapped in your calipers so don't do it

^^ Great post and very well put. I am a former class A master machinist with a aerospace background, couldn't have said it better my self. Not possible and will not be an option for any T6 6064, 6061, or even any 7-series aluminum calipers out there.

Agreed! And let's hope there aren't any 7000-series calipers out there -- well, at least not on my car!

ah thanks for the heads up. just some crazy idea i had looking at drill bits. cause i know they would be able to TAKE the heat. just didnt think of the trapping heat part or the whats it called specific heat something of aluminum? anyways bear with my off the wall thinking i guess =]. always good to learn more.
