An arc spray coating that is superior in both wear resistance and machinability, method of forming same, an arc spray wire used to form such a coating, and a cylinder block on whose bore inner surface is formed such an arc spray coating are provided. To this end, the arc spray coating contains Fe as a main component, 0.01% to 0.15% by weight of C, and at least 0.12% by weight of N, and the arc spray wire (wire) contains Fe as a main component, 0.01% to 0.2% by weight of C, and 0.25% to 1.7% by weight of Si, and may further contain at least 11% by weight of Cr as another embodiment.
