Nikasil Plating, how is it done and what is it?

What is involved in nikasil plating 2 stroke motorcycle cylinders? How long does the process normally take? does all the original plating have to be removed? If anyone could walk me through the process I would appreciate it. I work in the Heat Treating Industry and I am getting quite curious about nikasil platings. Thanks for any info I might receive.

I would like to know what preparations are needed to a standard bore cylinder when I am just changing pistons, (honing?)The original surface seems to be in good shape and I'm adding a forged piston with chrome rings. Can I just do a normal deglazing like a cast iron cylinder and install it?Thanks for your help.

It appears that there are many misconceptions / confusions about nickel/silicon carbide plating for automotive applications, particularly cylinder bores.

Fundamentally, it is probably the most beneficial process to be applied to small engine wear technology for many years. The process is not overly complicated, and results in a coating with properties of outstanding durability, oil retention and heat transfer characteristics which have combined to enable engine manufacturers to improve the performance of their engines and at the same time reduce weight and "bulk" of their product leading to emissions reductions and improved gas mileage.

My company is one of several companies around the world involved in this technology, and we are anxious to educate consumers and others about the process and it's applications.
