Surface preparation before spraying HVOF
Hi Gordon!
I'm a newbie of forum.
I have a shaft with diameter 35 mm. Some scratches have been happened and I plan to spray by HVOF process with Diamalloy 3006.
Please advise me how many of thickness do i have to skim shaft. I have skimmed shaft with a thin layer 01 mm, but i don't know it is correct or wrong.Now the diameter of shaft is 34 mm. Please advise me!
Thanks so much in advance.

Hi Minh,

Typically 200 microns would be sufficient. If you written in the old subjects , you can find some details information. :O
