Shot Peening Prior to Carburizing
Shot Peening Prior to Carburizing
(OP)
Anyone have any data indicating the impact of trying to carburize the surface of a 9310 material which has been shot peened PRIOR to carburizing? i.e does shot peened surface act as a mask? Is diffusion process impacted by high residual compressive stresses?
Any input would be welcomed. Thanks!

If you are asking about reprocess, then the "dimpling" has little effect, since the shot peen was on a very hard surface, and there is very little textural change.
There is concern, although I have seen no studies, that shot peening can "mask". I do not see a reason to suspect this, as previous posters state, the sp stress is removed upon heating.
My 2 cents.
