Greeting from Venture Engineering Thailand.

I would like to ask for some helps on Calender roll-WC17Co HVOF Coating. I have to admit that this was my first time spraying this kind of roll. 
The issue is after the roll was operated for 3 days, as you can see from the picture, there are some marks on the surface distributed all over the roll (like the coating bounce off). 
Moreover, there are cracks appear on the coating surface. (We did PT and it was fine before delivery). 
Now we have to re-coat it but we still have no idea what are these problems are coming from (especially, marks on the surface).

Pictures and Videos

Here are the coating details

1. HVOF coating (JP-5000)
   
2. WC17Co powder (particle size 15-45um and 15-53um)
   
3. We did HVOF coating for 400um in thickness
   
4. We sprayed 15-45um powder for 200 microns and the rest were 15-53um powders (we ran out of 15-45um powders so we had to use substituted powder)
   
5. The operator changed feed rate back and forth throughout the operation
   
6. Using slide way instead of handheld (but the gun was vibrated quite hard as you can see from the video)
   
7. Temperature control on roll surface was 100 C
   
8. Time interval of each ignition was 1-2 hours (as the cooling water was really hot, we had to wait)
   
9. Grind to 200 microns with roughness of 0.1 Ra
   

1. This is the Queen Calender roll
   
2. In the middle of King and Middle roll
   
3. It is working with doctor blade
   
4. The roll is in contact with chemical compound
   

I have a Metco Type 5P ThermoSpray gun for sale. Open to sensible offers and can offer secure postage at the buyers expense.

The gun appears complete and has the secure case with manual etc. Not been used for some time and I am selling on behalf of an elderly family member.

Happy to share images of what I have and answer any questions.

Hello All, 

Any suggestions on what is the best solution for high temperature (800C to 1000C) Electron-beam physical vapor deposition (EB-PVD) masking for gas turbine aircraft engine? Preferably some sort of tape, so it is easy to use.

Greetings All,
We have an application that requires Stellite 31 via HVOF. Looking for feedback on best powder for this application.

Thanks 
Dan

Hello everyone,

we have an issue with one of our PVD coatings: AlTiN.
In literature and on PVD suppliers websites you can see that AlTiN coatings can reach hardness around 3000-3500 HV (~30-35 GPa), but our coating has a hardness around 1500-1800 HV, does anyone have any idea why?

Some info:
-Target: AlTi 67/33 at%
-Deposition method: cathodic arc
