There is provided a laminate having a layer A on at least one side of a base material, in which the layer A contains at least aluminum (Al) and oxygen (O), and when a site corresponding to 5.0 to 25.0%, a site corresponding to 40.0 to 60.0%, and a site corresponding to 75.0 to 95.0%, in terms of length in a depth direction in the layer A, are defined as an X portion, a Y portion, and a Z portion, respectively, there are sites having a different composition ratio O / Al of aluminum (Al) and oxygen (O). There are provided a laminate that exhibits high productivity and less variation in gas barrier properties even with a thin film configuration, and a method for manufacturing a laminate.

Provided is a sliding component capable of suppressing a rise in sliding surface temperature. Sliding components 10 and 20 have sliding surfaces 11 and 21 sliding relative to each other. A base material 22 of the sliding component 20 is directly coated with a thin film 30 mainly made of glassy carbon, and the sliding surface 21 is formed by the thin film 30.

There is provided an aluminum-ceramic bonded substrate in which an aluminum plate comprising aluminum alloy is directly bonded to one surface of a ceramic substrate and an aluminum base plate comprising aluminum alloy is directly bonded to the other surface of the ceramic substrate, wherein the aluminum alloy is the aluminum alloy containing 0.05% by mass or more and 3.0% by mass or less of at least one element selected from nickel and iron in total amount, containing 0.01% by mass or more and 0.1% by mass or less of at least one element selected from titanium and zirconium in total amount, and containing 0% by mass or more and 0.05% by mass or less of at least one element selected from boron or carbon in total amount, with a balance being aluminum.

The application discloses a sludge brick blank drying method and relates to the technical field of drying. The method comprises the following steps: obtaining a surface evaporation rate and an internal moisture migration rate in a brick blank drying process; comparing the two rates with a preset matching relation algorithm; adjusting and controlling drying conditions according to a comparison result to make the two rates tend to match; and starting a fault-tolerant mechanism to maintain the drying process when data is abnormal or the adjustment and control fails. The application can solve product quality problems caused by the fact that the surface evaporation rate and the internal moisture migration rate do not match in the drying process.

Large diameter edges 111a to 111e formed in arc shapes having curvature radii larger than a ball radius R1 are provided. This allows improving surface roughness of a machined surface by cutting of a planar surface with the respective large diameter edges 111a to 111e compared with cutting of a planar surface with a ball end cutting edge formed in an arc shape having a single curvature radius. Further, since the respective large diameter edges 111a to 111e are formed in the arc shape, compared with cutting of a curved surface with linear cutting edges, surface roughness of a machined surface can be improved by cutting a curved surface with the respective large diameter edges 111a to 111e. Accordingly, a pick feed during the cutting of the planar surface and the curved surface with the respective large diameter edges 111a to 111e can be increased, and therefore machining efficiency in the cutting of both of the planar surface and the curved surface can be improved.
