Abstract
Provided is a high-toughness coating film having excellent wear resistance, in particular, resistance to cracking and peeling. A high-toughness coating film () includes a composition containing a mixture of metallic chromium, in which nitrogen is dissolved, and Cr2N. A content of the nitrogen in the high-toughness coating film is 2.0 to 8.5 mass %, and IP, which is expressed by total of each diffraction peak intensity of Cr2N/(total of each diffraction peak intensity of metallic chromium+total of each diffraction peak intensity of Cr2N), is 3 to 40% when 2θ is in a range of 30° to 90°, where θ is an incident angle in X-ray diffraction of the high-toughness coating film.
