Abstract:
A sprayed coating for a sliding member of the present invention includes a ferrous alloy containing chromium (Cr).
The sprayed coating for the sliding member has the content rate of the chromium of 8 mass % or more, includes a structure that comprises crystal grains contained in the sprayed coating and having an average grain size of 3 μm or less, has a Vickers hardness of 300 Hv or more, and then is excellent at abrasion resistance.
