Document Type and Number:
WIPO Patent Application WO/2020/090103
Kind Code:
A1
Abstract:
This coating is formed on a cylinder bore inner circumferential surface of an aluminum or aluminum alloy cylinder block, and is a coating of an iron alloy having iron (Fe) as the primary component thereof and including 8mass% or more of chromium (Cr) and 12% or less by Ni equivalent of austenite phase-stabilizing elements. The present invention can also provide a coating wherein the percentage of austenite phase present within the crystal structure of the coating is more than 0% and less than or equal to 20%, and the coating demonstrates superior adhesion to the cylinder bore, in spite of demonstrating superior corrosion resistance by having a high concentration of chromium.
