摘要:
A CMP conditioner having excellent corrosion resistance around abrasive grains includes a grindstone base having, formed on one side, an abrasive grain layer including abrasive grains fixed in a metallic bonding phase treated to form a first protective layer comprising an oxide on the surface of the metallic bonding phase of the abrasive grain layer by the sol-gel method. Subsequently, an aerosol obtained by dispersing fine particles of a brittle material in a gas is jetted and caused to strike on the surface of the first protective layer to form a second protective layer comprising a thick oxide film.

A sharp-edged blade of the invention includes a circular thin-plate-shaped abrasive grain layer 3 in which abrasive grains 2 are held in a bond phase 1. An oxide film manufactured by a sol-gel method is formed on the surface of at least the bond phase 1 of the abrasive grain layer 3 as a first protective layer 4. A thick oxide film which has polycrystals and is structured such that a grain boundary layer composed of a glass layer does not exist at an interface substantially between the crystals is formed on the surface of the first protective layer 4 as a second protective layer 5.

According to the present invention, a structure made of yttrium oxide is formed on a surface of a substrate comprises yttrium oxide polycrystals as a main component, a boundary layer made of hyaline does not substantially exist on a boundary face between crystals which form the structure, and both a cubic system and a monoclinic system exist in the crystal system of the yttrium oxide polycrystals. With this, it is possible to adjust the hardness of the structure made of yttrium oxide formed on a surface of a substrate to be larger than that of an yttrium oxide sintered body.
摘要:
There is disclosed a method for producing a film with use of aerosol which is capable of forming a film of satisfactory quality at an extremely high film formation rate. In the method, first, a carrier gas is mixed into fine particles comprising a brittle material as a main component and having a 50% average particle diameter of 100 nm to 300 nm on a number basis to form an aerosol. The aerosol is ejected onto the surface of a substrate to make the fine particles come into collision with the substrate, so that the collision crushes or deforms the fine particles to form a film on the substrate.

There is disclosed a method for producing a film with use of aerosol which is capable of forming a film of satisfactory quality at a high film formation rate. In the method, first, a carrier gas is mixed into a particle mixture which comprises raw fine particles comprising a brittle material as a main component and having a 50% average particle diameter of 0.010 μm to 1.0 μm on a volume basis, and auxiliary particles comprising a brittle material of the same type as or a different type from the brittle material of the raw fine particles as a main component and having a 50% average particle diameter of 3.0 μm to 100 μm on a volume basis, to form an aerosol. The aerosol is ejected onto the surface of a substrate to make the particle mixture come into collision with the substrate, so that the collision crushes or deforms the raw fine particles to form a film on the substrate.

摘要:
A composite structure forming method comprises the steps of first pre-treating brittle material fine particles to impart an internal strain to the brittle material fine particles, secondly causing the brittle material fine particles in which the internal strain has been created to collide with a substrate surface at high speed or applying a mechanical impact force to the brittle material fine particles containing the internal strain therein provided on the substrate surface, to deform or fracture the brittle material fine particles, re-joining the fine particles through active new surfaces generated by the deformation or fracture, forming an anchor section made of polycrystalline brittle material of which part bites into the substrate surface at a boundary section between the new surfaces and the substrate, and further forming a structure made of polycrystalline brittle material on the anchor section.
摘要:
A composite structure forming apparatus adapted to ejecting and causing an aerosol generated by scattering brittle material fine particles in a gas to collide with a substrate at high speed to form a structure made of the brittle material. The apparatus includes an aerosol generator for generating the aerosol, a nozzle for ejecting the aerosol, a shredder for shredding the brittle particles cohering in the aerosol and preventing cohesion of the brittle material fine particles, and a classifier for classifying the brittle material fine particles in the aerosol. The apparatus also includes a pretreatment device for creating internal strain in the brittle material fine particles, and a position control device for controlling the position of the nozzle relative to the substrate. The apparatus further includes a container having a sieve and a vibration device, and one or more of these components may be associated with the aerosol generator.
