Dear colleagues
Is there anybody using the cold spray on this site? What it would be your overall feed-back about it? How expensive is the equipment and the running costs compared with HVOF?
Is there somebody spraying Ti for example with cold spray? How does it work? Thank you for your input!
Best regards,
Florin

Hi Gordon and everyone,
I have interphase problems in spraying AMDRY 500F to Ti substrate. I have tried different grit blasting parameters to enhance surface properties and spray parameters to accelerate the splats to have better adhesion. Still the interphase has some oxide stringers and delamination. Can you please advise?

We just recived our SM-F100-Connex internal plasma spray gun (1700mm) from Sulzer Metco and I am curious if anyone here on the forum has any experience in using the Connex spray gun?
Best regards,

| HVAF assisted Twin Arc |

I am exploring a project here in the US that will require the use of HVAF assisted arc technology. I am familiar with the basics of the technology, but have yet to work with the equipment (though I have experience with both HVAF and Twin Arc systems).
The project is field application and TONS of square footage.
The ideal system can support guns that are as far as possible from the fuel source yet still generate densely packed splats and generous spray pattern (thousands of square feet one inch at a time is not reasonable).
Is anyone aware of equipment available for purchase that is suited for this application? UniqueCoat seems to have a solution that might work, but many of the HVAF/Arc systems out there are young and don't have much track record to judge by. It seems that many of the companies that have developed this technology to a point where it works have labeled it proprietary and kept it off of the market.
Help!

Hi everyone,
We are producing hardfacing powder. Our customers ( they have pta machine for hardfacing) have complaint about "cavity problem" on the moulds. they are using nickel based powder (NiCrBSi). Hardness 30-35 rockwell. We dont solve this problem. Otherwise we dont know the problem occuring from us or Customesr PTA machine.
Have a good week for everyone
