  INFO ON ROKIDE SPRAY SYSTEM
Posted by: ehasan - 08-31-2006, 04:18 AM - Forum: Surface Engineering Threads - Replies (11)

Dear Members,

We are having an existing Thermal Spray system from CASTODYN DS8000. We priarily use the system for Spraying CERAMIC COATINGS. We are planning to expand our capacity and are evaluating a new product ROKIDE MASTER JET from SAINT-GOBAIN.

The System uses CERAMIC STICK/RODS.

We would like to know the follwoing:-

1. Is it better then the conventional Powder Spray Torch.
2. The capital cost is higher then the conventional system But is it economical on maintenance & running cost.

We will appreciate feed backs on the matter to make a final decision.

Thanks
ehasa

  TBC disbonding
Posted by: darende - 08-25-2006, 12:52 PM - Forum: Surface Engineering Threads - Replies (9)

Dear,

Aircraft engine combuster has been made from 5 panels and all of them has to be TBC coated. Recently just 1 panel's TBC ( 360 degrees ) has been disbonded completely after engine testing, while bond coat was in place and at good condition. We have already performed all quality tests requested by OEM manual.

Anybody can help me to understand the root cause

  Plasma spray or HVOF ?
Posted by: Julio VALLES - 08-23-2006, 03:21 PM - Forum: Surface Engineering Threads - Replies (11)

First of all, thank's for giving me access to this forum.

For some applications, I've got problems to decide which thermal spray process is most adequate...
Are there any established preferences/rules to use plasma spray or HVOF for the following coatings :

1) abradable coatings
2) coatings on composite and polymer substrates

Or does it depend on the coated materials (HVOF best for metal, carbide cermets..., plasma spray best for high t? ceramics...)

  Dissimilar Metal Corrosion Protection
Posted by: BELLAMARE - 08-23-2006, 12:32 AM - Forum: Surface Engineering Threads - Replies (4)


Hello Group,

Is there a coating solution in order to avoid dissimilar metal corrosion between stainless steel and hard anodize aluminum?

I would like to coat stainless steel nuts with a "non-metallic product" to isolate it from being in contact with aluminum alloy.

I do not have the possibility of simply using plastic washers...

I will appreciate any of your suggestion?

Would Endura coating serie 300 with Teflon seal work for example?

Thank you for your help,

Cheers,

Charles

  thermal spray coating installation manufacturers
Posted by: J?r?me - 08-21-2006, 12:27 PM - Forum: Surface Engineering Threads - Replies (1)

Dear Gordon,

I'm currently exploring the market for a thermal spray coating installation. This will be used for aircraft engine parts but also some automobile racing ones.

Could you give me a list of well-known and experienced manufacturers who can provide me a turn-key installation for such coatings ?

Thanks !

  Fusing of cast iron
Posted by: Arturas - 08-16-2006, 11:55 AM - Forum: Surface Engineering Threads - Replies (1)

Hello,
I have such problem: I need to regenerate and to increase wear resistant of parts (Working conditions: transporting of steel sticks (temperature 900C))whish are made from grey cast iron. I tried to did it by using fusing of self fluxing coatings, but there appears cracks of coating and distortion of part.
I find material "Metco 439NS"SadAs-sprayed coatings are partially fused and require no further fusing, which makes them ideal for use with substrates that can not tolerate the fusing temperatures required by the self-fluxing alloys). Maybe it is solution????? And how to understand partially fused? (What temperature, properties of coating , adhesion resistant to impacts and so on????
Thanks
Regards, Arturas
