I've obtained both the Sept and Oct issue of Auto Sport and also the Oct issue of F1 Sokuho. I haven't read all of it and won't be able to translate any of it until later in the week but here are some parts that I've read.
It uses a patented process called Kumamoto "K" Plating and a new material was developed together with Honda for 2020. Both the material and process are proprietary and not available anywhere else in the world. It has been introduced to the cylinders to withstand damage from the piston rings. According to Kakuda Tetsushi, it has opened up a new world of potential for the Honda PU.
Kumabou holds the patents for electroless nickel plating and also the anodic oxide coating of aluminum called Alumite.
Not saying that is specifically what Honda RA620H is using but since that is what they specialize in I imagine it is along those lines of technology. It's quite different to Mercedes patented Nanoslide technology that uses arc spray of molten metal.
Ok this is their own "recipe" to the chrome ceramic it seems. The major Eurocompanies make a bunch of similar coatings. Aluminum oxide cermamics are filled in to the microcracks. It is for elasticity and hardness at the same time.
When i was in power industry was not uncommon to see companies offering new materials saying "we are the only ones in the world that make this!" but the other companies offering the same materials come and say the same.
For example federal mogul has at least three methods for these sorts of materials. Arc spray Is only one. The chrome ceramic is not arc sprayed.
Mmm, what you're saying is a possibility, but you're adding the ceramic part as pure speculation.
There is no mention of ceramic in any of that article whatsoever, not even a vague allusion to it. So the underlying tone of playing down an achievement and convinced "its done everywhere else" is sort of in poor taste.. especially considering it's entirely based on your own guesswork don't you think?
All these years, and I didn't know you can read Japanese.
The article itself is extremely vague. Even Ispano admits he is doing guesswork based on patent searches.
Why would Honda tell the public their secrets anyway? And how do they know other companies have not developed similar?
In materials science even a little difference of a tenth of a percent or slight change of process is patentable and be said proprietary. It is normal for many companies to do this. For example the non-galling alloy "Waukesha". Other company's made similar alloys but slightly tweaked. Essentially the same thing.. but not exactly the same.
My reasoning if that they are using chrome a this level you won't use chrome by itself. The trend in the new tech is to impregnate ceramics for better mechanical wear. Research and you will see. Honda won't say exactly this of course.
plating on current engine if translation is correct.
