Dear Gordon,
We are studying the Co28Mo17Cr3Si powder by plasma spray. But the result was not good, the unmelts and oxides didn?t meet requirement. We used 9MB Gun and 728 nozzle.
Can you help us,
How to solve this problem?
How should we do?
Thanks,
Best regards,

Posted by: karunanidhi - 09-02-2006, 12:34 PM - Forum: Surface Engineering Threads - Replies (1)

hi friends


its my pleasure to join with u, even though i had been in thermal spray society for a more than 1 year , i failed to join with u.

i feel proud to be in the thermal spray society , but one thing i am not able to under stand, wat are the limiting factors for wide spread of thermal spray around the world, especially in developing countries,
eventhough it was existed since the year 1910.

wat are the thing we can do for this.

i wish u all think abt it and reply as early as possible.

  Polymer Coating
Posted by: ehasan - 08-31-2006, 04:22 AM - Forum: Surface Engineering Threads - Replies (5)

Dear Members,

We are ineterested in setting up of Polymer Spraying unit for Rolls. Our primary intentions are for Coating with TEFLON/HALAR or similar products. We understand the coating can be carried out by ELCTROSTATIC SPRAY GUNS and subsequently baking in oven.

Our problem is how do we exercise the above baking procedure when the Roll dia is 1.0 m & 7.0 m in length. Will appreciate if someone can throw some light on the matter.

Thanks
Ehasan.

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

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
