8/17/2023 0 Comments Chromium oxide paste![]() Ken I plan to use my chromium oxide wheel after using the PA-70 leather wheel or the SJ wheel. Strictly out of curiosity, what are the advantages of using chromium oxide instead of PA-70? I will scrape off the excess paste and then see if the results get better after I have honed some more knives. That also explains why I have not gotten the results that I hoped for. I read that the amount of paste I bought should last a life time so I wondered why I had already used half of it. So the problem is that I have applied too much. So do not reapply it too often, only once in 4-6 months.Īhaaa.

I think that the Tormek oil does not dilute the chromium oxide very well. To make chromium oxide creamy, you can dilute it with liquid vaseline. I am relieved that you didn't write that I should buy a new wheel. What am I doing wrong? and what must I do now to get a well working chromium oxide wheel and how should I do it in the future? During use it can get a lot worse than shown on the picture and even though I regularly stop and wipe it away, I believe it is not supposed to be like this. The wheel now looks like this (3rd attached picture) and if you look closely you can see that the 'paste' sort of rolls off. I have done this several times prior to using the wheel and now I am unsure if it was the right thing to do. See 2nd attached picture.Īs I had no way of getting it out of the can, I applied a little of the oil that came with the leather wheel and with the help of a toothbrush I was able to dissolve (dilute?) some of the 'paste' and apply it to the wheel. Not like paste at all but more like a block of honing compound. ![]() When I received and opened the can of paste it was to my surprise very hard. I then ordered some chromium oxide paste, which I can no longer find online, but it is shown in the 1st attached picture. I bought a new leather wheel with the purpose of dedicating it to chromium oxide. Basically, it oxidizes as it is cut.I have run into some problems, so I hope you can help me. Following from the numbers in the first paragraph, that occurs in less than 100 nanoseconds. By ~10 L of exposure to oxygen there is a continuous oxide on the surface at 300K. Overall, there is not a huge difference between the two papers. They see chemisorption of oxygen in the first 1-2 L, nucleation and lateral growth of oxide islands up to 10 L, and continued growth of an oxide film above 10 L. Quantity Add to cart Share this: ChrOx is a great way to get a few more shaves out of your straight razors, or polish the bevel after a honing session. Palacio et al., "AES, XPS and EELS study of the initial oxidation of polycrystalline chromium", Surface Science 182(1-2) 41-55 (1987). 8.95 SKU MAG-CHRO-OX We currently have 54 in stock. At normal atmospheric pressure, with 20% oxygen in air, 1 Langmuir of oxygen hits the surface in about 6.6 nanoseconds (yes, nanoseconds).Īnother paper that could be of interest is C. It roughly corresponds to one monolayer equivalent of gas hitting the surface. One Langmuir is the exposure of a surface to a gas pressure of $10^$ Torr for one second. First, a definition of the Langmuir unit, used in the graph in the question, which is not often run across except by vacuum (particularly UHV) folks.
