I would like to ask for a help with application of abradable coatings.
We have two powders with compostion: NiSi13BNAlC and Ni20Cu20BN10CSiO2. Unfortunately I don't have more information so far.
Could anybody suggest which application to use for spraying, plasma or comb.flame spray?
Are powders with Boron Nitride suitable for plasma spray or combustion flame spray is preffered?

Thanks in advance.

RE: Abradables
Hi Karlos

These powder compositions don't fit with the common or traditional abradable powder products I'm familiar with, so I assume they are special products. From your information I don't think it is possible to predict which process they are design to be used with. The powder construction/particle size would be the main indicator to process required. Combustion powder spray, plasma and even HVOF could all be possible processes depending on how the powder is manufactured and graded.

Interesting compositions, I would also be interested to know more on these products.
