Cylinder crosshatch angle

WebNikasil is electroplated onto the cylinder bore approximately 0.004-0.005” 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 ...
