  • Patent number: 10287437
    Abstract: The present invention relates to a method for preparing pearlescent pigment through metal oxide coating based on a sheet-like substrate, and the obtained pearlescent pigment. The present invention further relates to a method for preparing pearlescent pigment through coating a sheet-like substrate by hydrolyzing metal salt under an acid condition, wherein a pH value is adjusted by using inorganics such as MgO, MgOH or CaCO3 that does not dissolve in water but can dissolve through reacting with an acid. According to the method, no free metal oxide is generated when the metal salt is hydrolyzed, so that the production cost is reduced, product quality is improved, problems possibly generated in an application process of the product are avoided, and a production process is more environment-friendly.

    Abstract: In S102, after preforming a pressed powder member by compressing metal powder filled in a press-forming portion, the pressed powder member and metal member are slid to each other in S103. In S104, after temporarily joining the pressed powder member and the metal member by further pressurizing the powder member, the temporary joined pressed powder member and the metal member are sintered in a sintering furnace, and the pressed powder member and the metal member are joined by sintering diffusion in S105. Thereby, joining areas between the pressed powder member and the metal member are increased, and it is possible to improve a joining strength between the pressed powder member and the metal member.

  • Patent number: 10246758
    Abstract: The invention relates to a method for producing a component from transformable steel by hot forming, in which a plate first is cut out of a strip or sheet as the pre-material, and is then heated to forming temperature and pre-formed, having an at least partially martensitic transformation structure after forming. Instead of a press mold hardening, the at least partially martensitic transformation structure is created in the pre-material, or in the plate to be formed, by austenitization and quenching already before forming, and then the thus-conditioned plate is reheated after forming, while maintaining the at least partially martensitic transformation structure, to a temperature below the Ac1 transformation temperature, and formed at this temperature.
