    摘要: The present invention provides a cermet coating that can take advantage of the hardness of a powder for a hard reinforcement phase more effectively, and spraying particles for forming the cermet coating. The cermet coating is formed on a base surface and has a hard reinforcement phase and a binder phase. The cermet coating has a Vickers hardness of from 50% to less than 100% of the hardness of the powder for a hard reinforcement phase, and has a surface roughness (center-line average roughness Ra) of less than 3.0. The cermet coating is formed by heating spraying particles prepared as aggregates of a powder for a hard reinforcement phase and a powder for a binder phase, and applying the spraying particles to a base at a supersonic velocity to integrate the powder for a hard reinforcement phase with the powder for a binder phase.

    摘要: Disclosed is a thermal spray powder of granulated and sintered cermet particles. The granulated and sintered cermet particles have an average particle size of 5 to 25 μm. The particles have a compressive strength of 50 MPa or higher. The particles have a straight ratio of 0.25 or higher, the straight ratio being defined as a value resulting from dividing the maximum thickness of a thermal spray coating obtained, when 150 grams of the thermal spray powder is subjected to thermal spot spraying, by the length of the longest of line segments each of which has both ends thereof on a contour of the spray coating. The granulated and sintered cermet particles have an average aspect ratio of preferably 1.25 or lower. The thermal spray powder is preferably used in applications where a thermal spray coating is formed by high-velocity flame spraying or cold spraying.

    摘要: A thermal spraying powder includes granulated and sintered particles of an yttrium-aluminum double oxide obtained by granulating and sintering a raw powder containing yttrium and aluminum. The total volume of fine pores having a diameter of 6 μm or less in one gram of the granulated and sintered particles is 0.06 to 0.25 cm3. The thermal spraying powder reliably forms a thermal spray coating that is suitable for use where the thermal spray coating is subjected to a thermal shock in a corrosive atmosphere or an oxidative atmosphere and for use where the thermal spray coating is subjected to a thermal shock in a state where the thermal spray coating contacts a member that has reactivity to a base material.

    摘要: A thermal spray coating is made of cermet and provided on the surface of a base. The value that is gained by further dividing the value, which is gained by dividing the coefficient of thermal expansion of the thermal spray coating by the thickness of the thermal spray coating (unit: μm), by the coefficient of thermal expansion of the base is set to a value no less than 0.15×10−2. Accordingly, peeling and cracking of the thermal spray coating can be prevented from being caused by the difference in the coefficient of thermal expansion between the thermal spray coating and the base.

    摘要: A thermal spray coating includes yttrium oxide at least as a main component. When the thermal spray coating is exposed to CF4 plasma and the plasma power of the CF4 plasma per unit area applied onto the thermal spray coating is 0.8 W/cm2 or greater, an etching rate by the CF4 plasma of the thermal spray coating satisfies the equation Re≦7.7×Pp2.2. Alternatively, when the plasma power of the CF4 plasma per unit area applied onto the thermal spray coating is less than 0.8 W/cm2, an etching rate by the CF4 plasma of the thermal spray coating satisfies the equation Re≦8.0×Pp2.2. In the equations, “Re”, represents the etching rate (nm/minute) by the CF4 plasma of the thermal spray coating, and “Pp” represents the plasma power per unit area (W/cm2) applied onto the thermal spray coating.
