    The end of microcoils?

    The early stages of titanium oxidation are very highly correlated with specific changes in the visible color one perceives when looking at the oxide film in normal daylight. If this doesn't happen, then no significant oxidation has occurred.

    The oxidation kinetics of titanium at 400F will be extremely sluggish. The oxide will develop very slowly. Why not conduct your own study? You could take some wire and put it in your kitchen oven (perhaps with and without an adjacent pan of distilled or deionized water to study the effect of...

    Catfish Atty Mods the next Chapter

    :( Yeah, I got two Vectors in the mail yesterday. I pulled the first one out and tore it apart and realized this probably wasn't going to be my next BF atty. Oh well, they're darn nice drippers.

    I think its important to include the effect of repeated, relatively high current pulsing of the coils for the appropriate number of cycles to simulate several weeks of use. This type of cycling could have significant effects on the development and reliability of the oxide film on the coil. Oxide...

    Here's another paper on thermal oxidation and corrosion of Grade 2 Ti. A key takeaway from these papers is that a continuous, adherent oxide film on Ti provides enhanced corrosion resistance. Although not directly applicable to vaping (Ringer's solution is NOT similar to Looper e-liquid), it...

    Good morning everyone. I found a link to a pretty fascinating research paper on thermal oxidation of Grade 2 titanium. The goal of the study was to identify a process to form an oxide film which might enhance the corrosion resistance of titanium in biomedical applications. Lots of good SEM...

    So has Pedro met the post requirements yet to post for himself? Just wondering.

    The bar keeps getting set higher and higher. At what point can we have a discussion about this?

    I think I know what to say. But I will keep it to myself to avoid inflaming this discussion any further.

    Sorry, I was busy dripping on my Velocity/Smpl rig. What did you say? :thumb:

    You guys are killing me. I would so love to BS about TiXN coatings on Fe and Ni alloys. Stop it now. :thumb:

    This paper is about some cheap over-fired cartomizer. What is the connection to hand-wound coils?

    Some people want to be reassured that everything is all "puppies and kitties and sugar and spice". Some people want to be reassured that they ARE paranoid and the world IS out to get them. And some people simply want to understand the world and find their own way through it in a way that makes...

    Props for sharing so much personal history in this thread. Because I am a current long-time employee of a major corporation, I am contractually bound not to represent myself as a spokesperson for my employer. Voluntarily disclosing too much about my prior employment history, publications and...

    LOL. You have NO idea what that short-lived, misclicked post was referring to. But whatever. It's the interwebs and you can assign any meaning to it that you like. Thanks for your input. I'll be sure to give it the consideration I think it deserves.:smokie:

    I'm going to leave my comments as they stand for tonight. Here's hoping eventually everyone makes an informed decision on how they want to choose and treat their coils.

    Is WHAT really necessary? I was simply pointing out that it could very likely be someone other than the Pedro Carvalho we have been discussing who created this account. And that they could be trolling this 31 page thread just to see what sort of response they can get.

    Actually, all of them will undergo some of these changes, but let's move on. Why do these oxides present a problem? Can you elaborate? There's actually a pretty huge body of scientific data that documents the temperature of formation of hexavalent chromium for different alloys in different...

    Did anyone notice that there is a new user, named "Pedro Carvalho", who joined e-cigarette-forum tonight? And he is currently watching this thread? Probably just some troll...

    I don't know where to start. Don't think I will right now. Which I'm sure several (if not more) of you will appreciate.
