摘要： A coating is formed on a surface of a base material of a furnace, and includes a base layer and a sliding material layer that is formed on a surface of the base layer and contains an oxide ceramic and a compound having a layered crystal structure. The sliding material layer causes the collided ashes to be slipped and facilitates the drop off of the adhered ashes. The base material forms a heat transfer tube or a wall surface of the furnace. The coating is also applied to a coal gasification furnace, a pulverized coal fired boiler, a combustion apparatus, or a reaction apparatus containing a furnace.

摘要： A hearth roll includes a base roll, a thermally sprayed coating formed on the base roll, and a modified coating formed on the thermally sprayed coating. The modified coating is formed by modifying a part or the whole of a surface of the thermally sprayed coating by melting and solidification of the thermally sprayed coating, by irradiating a part or the whole of the surface of the thermally sprayed coating with an energy beam. The thickness of the modified coating is from 2 to 20 μm, and the Vickers hardness HV of the modified coating is from 1.2 to 1.4 times larger than the Vickers hardness HV of the thermally sprayed coating.

摘要： A ceramic substrate is irradiated in an atmospheric air with a laser having a power density of 1.0×107-1.0×109 W/cm2 for an action time on an irradiation area of 1.0×10−7-1.0×10−5 s to roughen a surface of the ceramic substrate, as well as to form an oxide layer on a roughened surface. A thermal sprayed coating formed on the ceramic substrate sufficiently adheres to the ceramic substrate via the oxide layer.

摘要： 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 formed of Si. The amount of the second element in the thermal spray powder is 40% by mole or less. The mole ratio of the fourth element to the second element in the thermal spray powder is 0.002 or greater and 0.03 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.
