Abstract
The invention is to provide a coating structure material excellent in Mg corrosion resistance, which has resistance to corrosion caused by molten Mg and molten Mg alloys. The invention relates to a coating structure material including an Ni—Co-base alloy substrate and a Co-base alloy coating layer formed on the Ni—Co-base alloy substrate, wherein the Co-base alloy coating layer contains, in terms of % by mass, Ni: 20% or less, Co: 42% or more, Si: 2.8% or less, and Fe: 3.5% or less.
