Abstract: An insulated bearing includes an outer ring, an inner ring, and a plurality of rolling elements. At least one of the outer ring and an inner ring is made of metal, the plurality of rolling elements are provided between the outer ring and the inner ring, so as to be freely rolled, and at least one of the outer ring and an inner ring is coated with an insulating layer. The insulating layer is formed of a mixture in which silicon carbide and/or aluminum nitride as an additive are/is dispersed in aluminum oxide as a base matrix. The content of the additive is 1 to 40 mass % with respect to the total amount of the mixture.

Abstract: A component for a hot-dip metal plating bath includes a base material and a thermal spray coating disposed to cover a surface of the base material. The base material includes ferritic stainless steel that contains: C: 0.10% to 0.50% by mass; Si: 0.01% to 4.00% by mass; Mn: 0.10% by mass to 3.00% by mass; Cr: 15.0% to 30.0% by mass; a total of Nb, V, Ti, and Ta: 0.9% by mass to 5.0% by mass; and a balance of Fe and unavoidable impurities. The ferritic stainless steel includes a microstructure that includes a ferrite phase as a main phase and a crystallized carbide, an area fraction of a Nb carbide, a Ti carbide, a V carbide, a Ta carbide, and a composite carbide thereof to the crystallized carbide of 30% or more. The component contains 50% by mass or more of Al.

Abstract: Provided is a method for forming a thermal sprayed coating, including a step of spraying a non-oxide ceramic material on a substrate to form a coating by a high velocity oxy-fuel spraying process. An average particle size of the non-oxide ceramic material is 0.1 to 5.0 μm, and a particle size distribution of the non-oxide ceramic material contains one or more peaks in each of: a particle size range of 0.1 μm or more and less than 1.0 μm; and a particle size range of 1.0 μm or more and less than 10.0 μm. The non-oxide ceramic material is dispersed in a solvent to prepare slurry 11, and the slurry 11 is fed from the exterior to flame 10 jetted from a thermal spray gun 2 to form a dense thermal sprayed coating structure.
