    摘要: The present application refers to a method for treating a base material in form of metallic powder made of super alloys based on Ni, Co, Fe or combinations thereof, or made of TiAl alloys which treated powder is used for additive manufacturing, especially for Selective Laser Melting (SLM) of three-dimensional articles. The method is characterized in that
    - in a first step the chemical composition of the base material is determined and compared to a calculated target chemical composition with detailed amount of each element of the powder, which is necessary for the following SLM manufacturing process,
    - the powder is stored and atomized only under dry and pure protective shielding gas atmosphere and/or
    - the powder is treated by a post gas phase treatment, thereby adding or removing specific elements into or from the powder particles and adjusting the content of the added or already existing specific elements to meet the calculated target amount of each element according to the first step.
    It is an effective, simple and cost-efficient method for improvement of SLM powder manufacturing, powder post-processing and powder recycling.

    摘要: The hard coating layer includes at least a complex nitride or complex carbonitride layer expressed by the composition formula (Ti 1-x Al x )(C y N 1-y ). The average Al content ratio x avg the average C content ratio y avg satisfy 0.60≤x avg ≤0.95 and 0≤y avg ≤0.005, respectively, each of the x avg and y avg is in atomic ratio. The crystal grains constituting the complex nitride or complex carbonitride layer include a crystal grain having the cubic structure. Predetermined average crystal grain misorientation and inclined angle distribution exist in the crystal grains having the cubic structure.

    摘要: A vapor deposition reactor and a method for forming a thin film. The vapor deposition reactor includes at least one first injection portion for injecting a reacting material to a recess in a first portion of the vapor deposition reactor. A second portion is connected to the first space and has a recess connected to the recess of the first portion. The recess of the second portion is maintained to have pressure lower than the pressure in the first space. A third portion is connected to the second space, and an exhaust portion is connected to the third space.
