From Charles Navaro of LN Engineering:
This data is a sample coupon of a Nikasil® plated, used Porsche cylinder, below ring travel.
This surface is indicative of a freshly-honed Nikasil, NSC, or nickel silicon carbide plated cylinder bore. Nikasil is electroplated onto the cylinder bore approximately .004-.005” thick and is then diamond plateau honed. The crosshatch angle is typically shallower and the surface finish smoother than commonly found on steel or iron cylinder bores.
During break-in, very little changes to the surface profile on a Nikasil cylinder as the piston ring will wear in or break into the cylinder bore, unlike an iron or steel cylinder bore.
Measured via Zygo ZeGage Plus (10x)
