Dear Forum,

We are planning to use waterjet stripping machine to remove the coatings. As we are new to this waterjet stripping method, requesting for your valuable inputs to remove the coatings.

1. Can anyone share the parameters to remove the Ni-Al bond coat from Inconel parts?
2. What can be the good inspection method, to ensure the complete removal of coating?

Thank you
Arjun

Dear Forum,

Currently we are using Argon gas as primary gas in our plasma spray. As per the technical specification, the purity of the gas should be maintained. So we are purchasing the gas cylinders directly from a local vendor and he is ensuring the purity of the gas by testing in their laboratory. 

In future, we are having a plan to install a bulk tank to supply the gas continuously to the machine. Vendor is going to supply the Argon in the form of liquid and this liquid argon will be stored in the bulk tank. By using vaporization process this liquid will be phase changed from liquid argon to gaseous argon and this argon gas will be supplied to the machine.

1. What is the impact on gas purity due to this phase transformation from liquid to gas?

2. What are the ways to check the purity of the gas after conversion? 

Thank you,
Arjun

Dear All

Lately we sprayed WC10Co4Cr using TAFA JP-5000 on paper industry rollers. We only have 2 sets of parameter which are 98g/min and 55g/min. Normally we would use 98g/min parameters with an actual feed rate of 70g/min. The thing is this time we use 98g/min parameter with an actual feed rate of 98g/min as well. After spraying and grinding, there were some metal lumps all over the roller's surface. Now we are looking at two main reasons.

1. We didn't dry off the powder by heat before using it.
2. We used too high feed rate even the Bulletin suggested so. And that caused unmelts parameters due to insufficient heat.

Please find pictures here

Also, find parameters that I mentioned as attached files.

Any reply would be useful. Thanks guys

Hi,

I just discovered this useful forum.  
I am looking for spray parameter booklet for the f4 plasma gun. 

I would be very happy if someone can help

Good day

Hello all,

We're developing a repair that calls for Praxair Ni-248 powder sprayed using HVOF.

Does anyone have a suggested starting point for parameters for a DJ2600 gun?



Thank you in advance!

Dear friends,

We need help for SG-100 plasma spray parameters,

Does anyone work with SG-100 Argon-Hydrogen gun, We need CrO spray parameters, 

Thanks
