Hi Joanwang
Quote:Any idea about how to determine the thermal spraying turns ?
Not sure if I understand, but if is about speeds and feeds, cycles/passes of the spray gun these thread should help:

If you mean improving production rate rather than work quality, you can really only achieve this by increasing spray rates or improving deposit efficiency. Improving quality though, will help production rates if part rejection rate is lowered
If you mean being able to spray a part continuously rather than having wasteful periodic pauses for part cooling, then optimising speed and feeds (deposit per pass) and careful use of auxiliary cooling to enable continuous spraying will be beneficial to both production and quality. Achieving a constant part temperature throughout the spraying process is ideally the best situation, although much easier said than done
Making the effort to get close will yield benefits.
