The following plasma guns are available :

Model F3-30
F100
F210 ( this one was only ever commissioned)

Also have a fair supply of spare parts for these guns.


The powder feeder is a Twin 120 AH (inserts 1.5 DJ NL / 1.5DJ L)


The main power unit is also available, PT820/E

The system is being decommissioned.

To avoid the corrosion damage caused by cavitation and sediment erosion on the turbine blades, Fe-based amorphous coatings were deposited on steel of hydraulic turbine blades using plasma spraying with various spraying power. The effects of spraying power on the microstructure, electrochemical corrosion and wear resistance were systematically studied. Results show that the coatings have remarkable corrosion resistance and wear resistance compared with the substrate. Porosity is the most critical factor influencing the corrosion resistance of coatings. The anti-corrosion performance increases and the wear rate decreases as the spraying power increases. The coatings prepared at 25 kW has excellent corrosion resistance and wear resistance, with a corrosion rate of 0.011 mm·a−1, and a wear rate of only 5.91 mm3·N−1·m−1.

Hello all!
We are producing a very cost effective and high productivity arc spray system from years. Normally we were using in our shops but from two years we are also in market. 

Our system has following advantages;

Mobile 
Non-Stop spraying for days
Very low maintenance need
Usually in stock ready to sell
Very strong referances
CE certificated

Yes, our system is using in market leader boiler producers and market leader oil & gas companies. From now, each machine sprayed tonnes of metals and no any failure about machine. Very easy to use with free training and know-how sharings.

Hello all!

Any recommendations for a plasma (preferably) powder equivalent to SF Aluminum wire?

Thanks!

Hello Forum,

Requesting you to please provide the contact details of the supplier, who can provide the silicone rubber maskants for protection during plasma spraying?
It would be very helpful if the supplier is from India, as we are operating from India.



Thank you
Arjun

Hello All,

Now I have some questions about WC-Co coating:
1. What's the difference of the coating sprayed by APS and HVOF?;
2. How to choose the process, based on the working conditions or something else?
3. Is the coating sprayed by APS sensitive to the environment? I worked out this coating with APS（F4 gun） and sometimes the crack occurs without any change, the preheat temperature is around 80℃。

Dear Collegues
We starting work with 6P-II combustion flame spray with 40-years old metco powder feeder and 2gf flow meter. We are looking for user manual for this torch and starting procedure.
Can You help us in the case of starting procedure becourse during switchin from iginition to work it sometimes turns off. Which vales of pressure are recommended for the beginning
Best regards
Marek

I keep getting an ignition fault on my 9MC console.
I switched out electrode/nozzle and fault continues.
My next step is to switch out the -/+ hoses.

If this doesn't solve issue, what should my next step be?

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
