my customer needs to spray the part called : Hot cut dies plastic compound as per drawing attached.
please let me know if any of you have ever done this kind of spraying job.
your early reply is highly appreciated.
Kermetico Inc., USA started delivery of the Convertible HVAF and HVOF system.
33+ kg/hour (73+lbs./hour) tungsten carbide spray rate, up to 50 microns per pass resulting in gas-impermeable, ductile coatings both for HVAF (5-25, 10-30) and HVOF (15-45, 20-53) cut powders.
The first system is at work in the company design shop in Benicia, California, the second one is just shipped to the first customer.

I need an help in how to remove lines appearing between mount and coating in microstructure taken in 200X .
Powder used is stellite-12(HVOF spray)
Polishing method : Final polishing usind DAC (0.5-1micron diamond paste)
Note: If i replace the final polishing method using Chem pad and OPS solution then i dont get lines which i got using diamond paste (Water soluble)
I have a question on the tolerance capability level for thermal spray processes
.I would like to know, what is the best tolerance (i.e. +/- 0.00x) that can be achieved with HVOF or Air Plasma?
For my process
1. APS - I could achieve a deposition rate in the range of 0.001"~0.003" per pass.
2. HVOF - I could achieve a deposition rate in the range of 0.00025 ~0.0005
Any information would be appreciated!
I'm having trouble to reveal a true microstructure of Al12Si (arc wire sprayed). I believe porosity level more than it should, anyone has any polishing method for this coating?
Any help is greatly appreciated, Thanks
This AlSi (Aluminium 12% Silicone) top coat is applied onto NiAl bond coat (Dual Wire Electric Arc Coatings)
I have plunger which surface it is necessary to be rebuild with fully corrosion resistant coating. Coating thickness should be from 0,5 up to 1,5mm (There is different wear depth). Hardness should be 30-40HRC. Working conditions - pressure about 70atm, water, it works in pair with bronze B10 hub. Dimensions of plunger - diameter about 500mm length 10000mm.
I think about electric arc wire spray process and material SS420 ... but influence of porosity.... and how it works with bronze I don't know. Does anyone have ideas, experience....?
