I had the same problem when I was spraying Metco 45 chemical is
same as yours. We used 9MB Ar/H2 gas. the Oxide cluster is
identical to Gordon posted pictures. Alex and Ben, did you use the
front cooling jets? Maybe reduce the pressure of the front jet
will make it better. If the turbulent theory correct, (a
speicalist from PW told me the same thing and I do agree with
it)why increasing dwell time work? If reduce velocity, You
get higher porosity which is impt to this coat. You got the
optimize it. I am also very interested to learn it if someone make
it work.
Gordon, to your experience, does it happen to all hard-to-melt
coating?
Thanks, Hong
