Number of cycles/passes at a time
Hello SEF members,

Plasma spraying on rotating components: 
Initially I perform 5 to 8 cycles on the component and then measure the thickness. Based on the measured thickness I perform remaining cycles to achieve required thickness. 
Based on last two years data, it is observed that 13 to 15 cycles are required to achieve the required thickness.

Are there any risks if I perform directly 13 cycles at a time to achieve the thickness?

Thank you
Arjun

Hi Arjun,

Temperature of part and coating during process will be the main consideration.

Hi Gordon,

Thank you so much for your feedback.
Temperature of the part I will monitor and update here.
Can you please elaborate more about 'coating during process'?

Thank you
Arjun

Hi Gordon,

Temperature of the part reached to maximum 140 C.

Thank you

Dear Arjun,

As per Mr. Gordon's recommendation, it's always beneficial to maintain the part temperature below the standard limit. While the standard specifies 150°C, in my experience, I have gone up to 230°C without encountering any issues. However, I strongly advise keeping the temperature under 150°C. You can achieve 13 passes at a time by improving part/substrate cooling.

Best regards,
Demion Krishan
