Powder for thermal spray, thermal spray coating film, coating film and roll in molten metal bath
A thermal spray powder is provided that contains, as constituent elements, a first element selected from W and Mo; a second element selected from Co, Ni, and Fe; a third element selected from C and B; and a fourth element selected from Al and Mg. The amount of the second element in the thermal spray powder is 20% by mole or greater. The mole ratio of the fourth element to the second element in the thermal spray powder is 0.05 or greater and 0.5 or less. The thermal spray powder has a crystal phase containing Co, Ni, or Fe; W; and C or a crystal phase containing Co, Ni, or Fe; W or Mo; and B. In an X-ray diffraction spectrum of the thermal spray powder, the peak intensity attributed to Co, Ni, or Fe is at most 0.1 times the largest peak intensity in the same X-ray diffraction spectrum.
