Abstract

PURPOSE:To obtain an Ni-base alloy powder for thermal spraying, excellent in corrosion resistance as well as in wear resistance and adhesion, by incorporating specific amounts of Cr, Mo, Ta, P, N, Si, Mn, and C into Ni. CONSTITUTION:This Ni-base alloy powder has a composition consisting of, by weight, 15-35% Cr, 6-24% Mo, 1.1-8% Ta, >0.03-0.3% p, >0.1-0.5w N, >0.3%-5% Si, 0.0001-3% Mn, 0.001-0.1% C, and the balance Ni. This alloy can further contain one or more kinds among the following (a), (b), (c), and (d): (a) 0.01-20% Fe; (b) 0.001-1% B, 0.001-0.1% Zr, and 0.001-0.01% Ca; (c) 0.1-1% Nb, 0.1-4% W, and 0.1-4% Cu; (d) 0.05-0.8% Ti, 0.01-0.8% Al, 0.1-5% Co, and 0.1-0.5% V. A thermally sprayed layer formed by using this Ni-base alloy powder has high hardness though it is nearly equivalent to a thermally sprayed layer formed by using conventional powder, and further, it has superior corrosion resistance because of its remarkably excellent peeling breaking stress when it is formed into a substrate.

て優れた性能を発揮するものである。From the results shown in Tables 9 to 12, the thermal sprayed layers formed of the thermal spraying powders 1 to 85 of the present invention have substantially the same corrosion rate as the conventional thermal sprayed powder 1 formed. From a certain point, it can be seen that although the corrosion resistance is almost the same, the hardness is high and the peeling fracture stress to the substrate is remarkably excellent, and thus the wear resistance and the adhesion are excellent. However, the comparative thermal spraying powders 1 to 16 are out of the scope of the present invention in the content of any one of the constituent components (marked with * in Tables 7 and 8), and the comparative thermal spraying powders 1 to
It is apparent that the thermal sprayed layer formed in No. 16 has cracks in the thermal sprayed layer after thermal spraying, or even if the thermal sprayed layer has no cracks, at least one of the above characteristics is inferior. In addition,
Although thermal sprayed layers were tested in the examples, similar results were obtained with build-up welding formed using the thermal spraying powder of this invention. As described above, when the thermal spraying powder of the present invention is used, it can be used for a long time in a chemical / smelting plant or the like under sulfuric acid or hydrochloric acid as a stirring rod, a container or the like that is a structural member of a slurry dissolving device for ores and the like. It is possible to provide a composite material that can be obtained, and to bring about an excellent industrial effect. Incidentally, the composite plate using the powder for thermal spraying of the present invention,
Since it has high wear resistance and excellent corrosion resistance, for example, chemical plants, non-smoke desulfurization equipment such as boilers and structural members such as semiconductor devices, food processing and pharmaceutical equipment, and hands exposed to seawater etc. When applied as a tool member or the like, it exhibits excellent performance for a long period of time even in practical use under severe conditions.
