Electro Spark Surface Deposition Machine
   

Hi,

We are working on feed crushing blade coating. We applied hot coating WC/Co+NiCrBSi %50 but not get enough service life. I saw some brazing application and an electro spark surface coating machine.

It's name is Rocklinizer. It works on 3 different electrode. TitaniumCarbide, TungstenCarbide.

Is any body try to use this machine?


Is any body know the bonding strength ?


What is the correct application this like surface parts? (Feed crushing blade, crushing hammer, farming blades ect)


I check some doc. about this machine. I thing may be work well on this like application.

Thanks for your reply.

RE: Electro Spark Surface Deposition Machine
My experience with electrospark deposition is that it is extremely slow and applies a very thin layer of tungsten carbide on the part. I have never seen bond strength data. It would probably take you a week to coat your crusher parts with this machine.

Why did you choose the WC/Co-50NiCrBSi coating material? An 86WC10Co4Cr coating would provide better wear protection because it has a much higher carbide concentration.
