    Corrosion resistant coating for 4140 shaft

    Tbuelna and EdStainless, Thank you for the thoughtful replies. I have used CERAM-KOTE for an actuator on a subsea XMASS tree. What we did was applied it (ceram-kote) thick then precision ground to final dim's. This was applied onto INCONEL 718, so the base material was already corrosion...

    Partial Pressure

    For O&G, a lot of concerns center around partial pressure of H2S when selecting material, specifically for sour gas compliance. I think the relevant specification is NACE MR0175.

    Corrosion resistant coating for 4140 shaft

    Thank you both for your suggestion. As indicated in the original post, our goal is to select a different coating for the existing 4140 shaft to provide better corrosion resistance. That said, would any of the following work? 1. Nickel Plating 2. Diamond Like Coating (DLC) 3. Ceramic...

    Corrosion resistant coating for 4140 shaft

    Hello All. The subject of this topic is corrosion resistant coatings for 4140 base material. The application is a shaft of a linear actuator used in a saltwater spray environment (aft deck of a ship). The current shaft is processed with a conversion coating known as QPQ (quench polish...

    Simulation Design Study

    Also, Is there a way to rename your sensors? For example 'Displacement 5' would be much easier to understand if it read 'Displacement - X direction'. Can you rename Scenarios? For example 'Scenario 1' would be much easier to understand if it read 'Load Case 1' or something of value to the...

    Simulation Design Study

    Hello, I am having trouble defining stress/displacement plots using the design study feature of SIM 2010. The problem I am working on involves 10 different load cases applied to the same locations on the model. I am using variables for the x,y,z components of these loads (which vary from load...
