Hi Jaydev Choudhary
Quote:i want to know that what is maximum thickness of coating possible with thermal spray process
I have seen coatings up to about 75mm (3 inch) thick. These were purely curiosity/artistic with no real practical application.
Depending on spray material, substrate, process characteristics - coating thickness limitations can vary widely from about 0.25mm up to an unknown limit.
Quote:what is maximum temperature any thermally sprayed substrate can withhold?
Can you be a bit more specific with your question? are we talking about coating process temperatures or service temperatures?
Its a bit like being asked how long is a piece of string
