摘要
The present invention provides a surface-coating material capable of exhibiting high peeling resistance and high chipping resistance. A surface-coating material is provided with a base material, a bottom layer, and a top layer. The base material comprises high-speed tool steel or cemented carbide. The bottom layer is provided on the surface of the base material and comprises at least one nitride of titanium, aluminum, chromium, and zirconium. The top layer is provided on the surface of the bottom layer and is formed by alternatingly laminating an A layer and/or a B layer. The A layer comprises a nitride of aluminum, chromium, and silicon. The B layer comprises a nitride of aluminum, chromium, and yttrium.
