    Abstract: The present invention relates to a preparation method of a tungsten carbide sintered body for a friction stir welding tool used in a friction stir welding tool of a high melting point material such as steel, titanium and the like or a dissimilar material such as aluminum, magnesium-steel, titanium and the like. The preparation method comprises the following steps: filling a tungsten carbide (WC) powder in a mold made of a graphite material; mounting the mold filled with tungsten carbide powder in a chamber of a discharge plasma sintering apparatus; making a vacuum inside of the chamber; molding the tungsten carbide powder while maintaining a constant pressure inside the mold and increasing the temperature according to a set heat increase pattern until the temperature reaches a final target temperature; and cooling the inside of the chamber while maintaining the pressure pressurized in the mold after the molding step.

    Abstract: A regenerative fluid machine having guide vanes on a flow channel wall is disclosed. The regenerative fluid machine includes a circular plate-shaped impeller having a plurality of vanes radially formed on an outer circumference thereof at regular intervals, casings in which the impeller is housed, and flow channels, each of which has a suction hole and a discharge hole in opposite ends thereof, and which are circumferentially disposed within the casings so as to face the vanes. The plurality of guide vanes having an inclined angle (θ) with respect to a radial direction protrude from the flow channel wall in a rotational direction of the impeller so that a relative inflow angle (β) of the fluid introduced into the impeller grooves is increased and thus an absolute inflow angle (α) is decreased.
