    Modeling a rotary Eccentric Shaft

    Thank you, yes that was correct. The drawing was a little vague.

    Modeling a rotary Eccentric Shaft

    Hello all, I'm working on a model in Creo 6.0 of an eccentric shaft for a rotary (Wankel) engine. I'm struggling to model this draft feature on one of the lobes. You can see from the drawing it starts out as a 45 degree draft and then tapers to a 30 deg draft but I've yet figure out how to...

    Underwater stainless and bronze bushing corrosion

    We investigated the 303 parts including wiping them clear of the corrosion and could not see any pitting or wear marks. The corrosion must have started on the bronze bushings and transferred to the SST parts during operation.

    Underwater stainless and bronze bushing corrosion

    You are correct with that assumption on selecting 303! Do you have a recommendation on magnification scale to make this pitting observation?

    Underwater stainless and bronze bushing corrosion

    Water quality depends on the site, but acts as a moderator for nuclear fuel reactivity in the primary system. It can consist of Boron, Iron, Silica, Magnesium, Calcium, Aluminum, Fluoride, Chloride, and Sulfate. Keep in mind the sulfate, chloride, flouride, and silica are in the range of 1-1200...

    Underwater stainless and bronze bushing corrosion

    Forum, I need help trying to determine why the SAE 660 bronze bushings in our underwater nuclear fuel handling tool are experiencing aggressive corrosion rates. The two pictures below are just two examples of some of the types of corrosion we're seeing. From my understanding the blue color is...

    Corrosion on underwater usage for SAE 660 Bronze Bushings, Need Alternatives

    Forum, I need help trying to determine why the SAE 660 bronze bushings in our underwater nuclear fuel handling tool are experiencing aggressive corrosion rates. The two pictures below are just two examples of some of the types of corrosion we're seeing. From my understanding the blue color is...

    Dry Underwater Bushings in High Radiation Fields

    A small update to this thread in effort to gain more traction. I inspected the Graphalloy bushings post deployment after they had spent ~72 hours resting on top of an irradiated fuel assembly. Thankfully no swelling, scarring, or wear was found and will be going back in the field next month...

    Dry Underwater Bushings in High Radiation Fields

    Hello All, I'm looking into broadening my departments horizon on available bushing material for some of our equipment designs. Quick background, I work in the nuclear industry and develop hand operated equipment that interfaces directly with irradiated fuel assemblies. The bushing must be able...
