  • Publication number: 20040229071
    Abstract: An aluminum alloy article is cleaned to remove oxides and organic matter from a coatable surface, coated with a composition comprising an organic resin and a fluorine compound, and then heated to an elevated temperature to decompose the organic resin and at least a portion of the fluorine compound. After heating the coated surface is left with a protective oxyfluoride film that prevents blistering and hydrogen pickup and promotes hydrogen degassing from the article.

  • Patent number: 6737153
    Abstract: A circuit board comprising a composite resin and a metal plate, the metal plate forming circuit patterns. The composite resin comprises 70-95 parts by weight of inorganic filler, and 5-30 parts by weight of a resin composition including a thermosetting resin and a hardener. The metal plate is surface treated to reinforce the adhesion at least at one surface contacting with the composite resin. The composite resin fills spaces between the circuit patterns, and the composite resin composition and the metal plate form a plane at a side of the metal plate for mounting components. Since the resin composition including the inorganic filler is also present in the spaces between circuit patterns of a metal plate, heat dissipation characteristic of the circuit board is extremely high, and is suited for electronic apparatus containing heat generating parts such as power circuit.

  • Patent number: 6678936
    Abstract: A coating method according to the present invention includes a step of producing plural exterior members which constitute the outside portion of a vehicle body, and a step of forming and joining plural inside members which constitute the inside portion of the vehicle body, thereby producing a chassis. Each of the exterior members is a precoat metal sheet in which a rust-preventing layer and a coat which contains a lubricating component are formed on a surface of a metal sheet. Accordingly, the exterior members joined to the chassis need only intermediate coating and overcoating. The chassis constituent members are made of a precoat metal sheet in which a rust-preventing layer which contains a lubricating component is formed on a surface of a metal sheet. Accordingly, it is not necessary to carry out electrodeposition coating which is considered to be necessary for the chassis.

    Abstract: An aluminum alloy brake disc body for a disc brake device is provided with a metal layer of a high wear-resistance. The high wear-resistance metal layer is configured to reduce thermal stresses within the aluminum alloy brake disc body so as to inhibit warping, bending or flexing of the brake disc when heated during braking. The high wear-resistant metal layer also is applied to the aluminum alloy brake disc body in a manner reducing manufacturing costs. In one mode, a plating layer made of a metal having a high wear-resistance is formed on a frictional surface of an aluminum alloy brake disc body. Cracks in the form of a fine network are formed in the whole area of the plating layer. The cracks can be formed by a plating process, by nitrosulphurization, by heating, by burnishing or by use of the plated component. The cracks advantageously provide for expansion between the individual metal fragments and, thus, create an expandable plated wear surface.

  • Patent number: 6319620
    Abstract: This invention provides a composite foil comprising an organic release layer between a metal carrier layer and an ultra-thin copper foil, and a process for producing such composite foils comprising the steps of depositing the organic release layer on the metal carrier layer and then forming an ultra-thin copper foil layer on said organic release layer, preferably by electrodeposition. The organic release layer preferably is a heterocyclic compound selected from triazoles, thiazoles, imidazoles, or their derivatives, and provides a uniform bond strength which is adequate to prevent separation of the carrier and ultra-thin copper foil during handling and lamination, but which is significantly lower than the peel strength of a copper/substrate bond, so that the carrier can easily be removed after lamination of the composite foil to an insulating substrate. The invention also includes laminates made from such composite foils and printed wiring boards made from such laminates.

  • Publication number: 20010023028
    Abstract: A soldering method, which secures reliable joints without using flux, is disclosed. Soldering is performed using an auxiliary connecting material capable of physically destroying and dispersing an oxide film, which is naturally grown on the surface of a main connecting material such as solder or brazing between two terminals, to realize a reliable solder wetting (a state of the main connecting material being fused and mixed). For an auxiliary connecting material, hydrocarbon such as n-tetradecane (C14H30), for example, can be used. N-tetradecane boils between connection surfaces and cubically expands; energy generated therefrom physically disperses the oxide film and causes a fresh surface to be exposed; solders on both terminals are mixed; and an electrical and mechanical joint is securely achieved. The residue of the auxiliary connecting material is an insulating material, and therefore does not need cleaning. An excellent electrical joint which is moisture-resistant as well as highly reliable is attained.

  • Patent number: 6284391
    Abstract: A method for forming a sol-gel on a metal surface to provide an interface for promoting adhesion between the metal surface and an organic resin involves application of at least one metal alkoxide compound having at least one labile sulfur atom, and at least one metal alkoxide compound having at least one reactive moiety which is capable of bonding with an organic resin. The metal alkoxide compound having at least one labile sulfur atom is capable of bonding to various metal surfaces, including surfaces of noble metals, such as gold, by a sulfur-metal linkage with the metal surface. The metal alkoxide compound having at least one labile sulfur atom reacts with the metal alkoxide compound having at least one reactive moiety which is capable of bonding with the organic resin to form a sol-gel which bonds to the surface of the metal, and which includes reactive moieties which are capable of bonding with an organic resin.

  • Patent number: 6190788
    Abstract: Disclosed is a method for the formation of a silica coating film having a remarkably high crack-forming thickness limit on the surface of a substrate which may be highly heat resistant, for example, having a circuit wiring layer of polycrystalline silicon to withstand a temperature higher than 500° C. without excessive diffusion of dopant through the source layer or drain layer of the semiconductor device. The method comprises the steps of: coating the substrate surface with a coating solution containing a modified polysilazane which is a reaction product of a polysilazane and a dialkyl alkanol amine, drying the coating layer, subjecting the coating layer to a first baking treatment at 350-450° C. for 10-60 minutes and subjecting the layer to a second baking treatment at 550-800° C. for 0.5-60 minutes.
