i need help in selecting the correct coating material for our application.
We want to apply a ceramic coating on Vehicle Exhausts by Plasma Spraying.
The actual mechanic attributes of the coating are not important, as we do the coating only for aesthetics.
Important points are only:
- The coating needs to be dark grey-black. The darker the better
- The coating needs to be heat resistant. Our exhausts are usually at around 400 degrees Celcius, but can reach up to 800 degrees for a short time.
- The coating needs to be ready "as sprayed". Due to the shape and tolerances in shape/size of our exhausts, it's not feasible to grind/polish the coating after it has been applied also application of a sealer is not an option.
The manufacturer of our Plasma Spray equipment suggested us a ceramic 60% Aluminium Oxide 40% Titanium Dioxide
We tested it and we're very happy with the surface quality/roughness as well as with it's heat resistance.
The only problem is that this material is rather light gray/blueish, we can not accept the color.
I would greatly appreciate suggestions for other possible coating materials which we could try.

Hello, have anyone experience with spraying molibdenum by plasma? I use reference parameters for f4mb gun, which are a little bit changed due to better morphology but i've achieved a small hardness below 500HV. Any suggestions? I've checked the range of paremeters 600-630A, 40-47Ar, 8,5-10 H2.
My name is Max Caprez from Industrial Technologies. We are a company that designs and manufactures molded masking. We have been in business 20 years and work primarily in the aerospace and medical industries. We are located in Akron, Ohio USA.
We design low cost molds and tooling for a specific part and manufacture masking from said mold.
We make masking for abrasive blasting/peening/thermal spray.
We have many years of experience in the masking of medical implants and understand how to work with companies during the process validation.

I have a cracking problem in a ceramic material 87- 13 Aluminium dioxide- Titanium dioxide plasma spray (Metco 7M system).
The parameters used are the next:
Standoff 4-5 in
Feed rate 110
Feed rate 30 gr/min
Flow 80 ( Ar) 100 psi pressure
Flow 20 (H2) 50 psi pressure
Using the attached photo, What canbe the reason of the cracking problem? it could be a coating overhating?
We produce high-velocity thermal spray equipment in the USA, looking for agents/distributors in India, Japan, Korea, and Mexico.

I've developed a JP5000 barrel, that so far, is lasting 45 times longer than OEM and is still running. My company is in the business of making TS consumables. My question is why would I want to make this barrel and is there a real need for it. Our company would loose business if we sold it, because we would sell fewer barrels.

Hello, i need an opinion about BST, how deep can penetrate the glue into the coating? The metalic coating manufactured by plasma or hvof (dense with max. porosity 5%). I wonder about the legitimacy of testing the coating with thickness about 150-200um. Is it possible that the glue can penetrate until the base material? In my opinion is not possible, but i've met with different opinion. Additionally i need to understand how deep can penetrate the sealant, for example METCOSEAL.
