- a first powder comprising Cu and Sn;
- a hard particle powder consisting of a Laves phase consisting of Si:
- 3% to 7% by mass, Fe:
- 2% to 16% by mass, Mo:
- 24% to 28% by mass, Co:
- 14% to 20% by mass, Cr:
- 1% to 10% by mass, Sn:
- 1% to 15% by mass, and Cu:
- the balance, per 100% by mass of the whole hard particle powder;
- and
- a second powder comprising Cu, Co, Fe, Ni, Si, and Cr and further comprising Sn at 1% by mass or more.
