I apologize for any confusion that I may have caused, but I misspoke. We can deposit either silicon CARBIDE or graphite or any other secondary particles such as teflon, silicon nitride, aluminum oxide, or PEEK resin in the Composite Electro Coat.
The initial development of this product was to provide a lower cost to pure silicon carbide counterseats used on mechanical seals. What we are finding is that this plating is also ideal against other dynamic sealing applications, such as C seals or other. Advantage here is extreme hardness and therefore long life.
By dispersing graphite (or teflon) in the nickel-base plating, we get excellent dry running capabilities, as carbon is considered "self lubricating". Depending on your application, it may be possible to combine two or more secondary particles.
The plating thickness is directly related to the length of time in the bath. Most of our platings have been in the 0.025mm to 0.06mm range prior to grinding. Higher thicknesses are possible as well.
Depending on your application, the high carbon steel washers may need to be ground. We have found the initial coating to be somewhat uneven, and needs to be ground to an acceptable level.
If you would like more information, please advise.
