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 smooth roll (1) having a surface layer with water-retaining function is obtained by a method for producing a milling roll, comprising: a roughening process for blasting a surface (2a) of a roll substrate (2) constituting the smooth roll (1); and a coating process for spraying a thermal spray material over the roughened surface (2a) of the roll substrate (2) so as to form a thermal sprayed coating (3) having pores (5) that retain water. Satisfactory cereal powder is obtained by preventing drying of cereals in a milling process and retaining an adequate water content.

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.

摘要: A coating material and a surface coating method for an in-furnace structure, and an in-furnace structure that are excellent in resistance to corrosion by the sulfur group. The coating material for an in-furnace structure used in a high-temperature corrosive environment including a sulfur group element includes as component composition, by mass, Co: 45% to 72%, both inclusive, Mo: 20% to 35%, both inclusive, Cr: 8% to 25%, both inclusive, and Si: 0.1% to 5%, both inclusive, and substantially without Ni. In the surface coating method used in a high-temperature corrosive environment including a sulfur group element, a coating is formed on a surface of the in-furnace structure by overlay welding or thermal spraying of the above-described coating material. In the in-furnace structure used in a high-temperature corrosive environment including a sulfur group element, a coating using the above-described coating material is formed on a surface of the in-furnace structure.

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 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.

摘要: A low pressure plasma spraying method includes turning working gas into plasma by direct-current arc to generate a plasma jet while setting a plasma power source output to 2 to 10 kW in a pressure reducing vessel and feeding raw material powder having an average particle size of 1 to 10 μm into the plasma jet from feeding ports of a thermal spraying gun to form a thermal sprayed coating, which can suppress transformation of the raw material powder and form a dense coating.
