Abstract
In one or more embodiments, a method of forming a coated cylinder bore includes honing a cylinder bore to produce a honed cylinder bore, masking partially the honed cylinder bore to form a partially masked cylinder bore, and contacting the partially marked cylinder bore with an electrolytic bath to form the coated cylinder bore. The method may further include applying a pulsed direct current at a voltage of 400 to 500 volts to the electrolytic bath. The contacting step may be carried out via one or more of plasma electric oxidation, plasma electrolytic deposition and micro arc oxidation.
