  Effects of spraying power on Fe-based amorphous coatings
Posted by: Avarichards - 04-10-2024, 12:07 PM - Forum: Surface Engineering Threads - No Replies

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.

  Silicone rubber masking
Posted by: ArjunAnnam - 02-05-2024, 06:32 AM - Forum: Surface Engineering Threads - Replies (2)

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.

  WC-Co sprayed by APS and HVOF
Posted by: Zhao Yun - 01-31-2024, 08:15 AM - Forum: Surface Engineering Threads - Replies (5)

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℃。

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?

  Coating removal by waterjet stripping
Posted by: ArjunAnnam - 11-27-2023, 11:20 AM - Forum: Surface Engineering Threads - Replies (1)

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

  Purity of process gas
Posted by: ArjunAnnam - 11-21-2023, 05:41 AM - Forum: Surface Engineering Threads - Replies (1)

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
