Mein Anliegen ist recht einfach. Mich interessiert, was die Kashima
Beschichtung (z.B. auf Fox Fahrwerken) bringt. Nackte Zahlen wie
Reibwerte und Haltbarkeitsinfos sind genauso erwünscht wie
Erfahrungsberichte von Usern die mit/ohne 1:1 vergleichen können.
Ein wenig schwierig wird der 1:1 Vergleich, da Kashima beschichtete
Federelemente wohl mit etwas anderen Druckstufeneinstellungen arbeiten,
um einem durch den geringeren Reibwert verursachten Wegsacken
entgegen zu wirken.
Das Ding ist, viel findet man dazu nicht im Netz.
Hier ein paar Hintergrundinfos des Herstellers:

In the revolutionary Kashima Coat process, lubricating molybdenum disulfide is deposited, via electrical induction, into the billions of micropores on the surface of hard-anodized aluminum. With its debut on the international mountain bike racing circuit, the distinctive gold colored, Kashima coated stanchions maintain better lubrication characteristics, and the lightweight aluminum components treated with Kashima Coat attain a level of hardness and abrasion resistance four times tougher than standard hard-anodized aluminum.

âWhen you are racing on the World Cup level, a huge percentage of races can be won or lost in the preparation of the bike â the seemingly small details that take the bike from good to excellent,â said 2008 Downhill World Champion, Gee Atherton. âThe Kashima coating made the forks so much more reactive to the small hits that I would normally feel on rough terrain. When the forks were skittering over tiny bumps they could soak up the impact much more quickly, without giving me so much feedback through the bars. Thatâs a huge advantage on long courses.â

Bei den Gabeln wurden die FIT-Kartuschen überarbeitet, was noch weniger Reibung zur Folge haben soll. Dazu arbeitet man mit exklusiv von den italienischen Lagerexperten SKF gefertigten Dichtungen. Um der geringeren Friktion gerecht zu werden und etwa ungewolltes Wegsacken an Steilstufen zu verhindern, erhöhte Fox die Druckstufe der Factory-Gabeln.

Basically, the Kashima Coat can lead to a longer lasting fork upper due to better lubrication properties and better wear and scratch resistance than standard fork uppers.

Many will ask what the difference is between Kashima Coat and the Titanium Nitride coating process that other manufacturers have used in the past, and that the machining industry has used on cutting heads for the last few dozen years.
We spoke to Fox Engineer and Executive VP Mario Galasso, and this is what he had to say about it:
âHmmmâ¦.great question.
Hereâs the hmm part. Ti-Nitride is lower friction and harder/more wear resistant than aluminumâ¦IF it is applied properlyâ¦and IF it is used in the right application.
You have to chrome plate or electroless nickel plate the aluminum first. Then Ti-Nitride on top of the chrome or en. Chroming or en-ing aluminum is prone to flaking. And since the chrome or en, and ultimately the ti-nitriding is so much stiffer than the aluminum base metal, it is even more prone to flaking/delamination in applications that see flex loads, like fork upper tubes.
Kashima provides most of the wear resistance and low friction properties of tinitriding, but does it in a very stable, repeatable and less expensive way, with none of the downside delamination/flaking issues associated with tiNitriding aluminium and/or flex load applications. It is also more environmentally friendlyâ

- Angaben Hersteller:
- je nach Aluminium und Schichtdicke sinkt der Reibwert von
0,20(0,21) auf 0,17(0,14) von Kashima Coating gegenüber
Hard Anodisieren. - Korrosionsbeständigkeit liegt je nach Schichtdicke und
Aluminiumlegierung bei 500 bis 1500h - es gibt keine Infos über die Reibpartner
- Härte von Kashima beschichtetem Alu liegt bei bis zu 400HV
- die Diagramme des Datasheet (Anhang) sind auch interessant,
wobei es glaubhafter wäre hätte ein neutrales Labor diese Daten
erzeugt.
