Abstract: An iron member having a coating film on at least part of its surface is manufactured by a step of projecting zinc particles to the surface of a base material made of an iron material to form a base film, and a step of forming a coating film of resin coating material on at least a part of the base film.

Abstract: In a brake member having a brake lining bonded to a brake shoe, the brake shoe has a chemical conversion coating provided on the surface thereof and a ceramics coating layer provided on the chemical conversion coating which has been formed by dipping in a ceramics precursor solution. The brake lining is bonded to the ceramics coating layer by heating under pressure. A method for bonding a brake lining and a brake shoe is provided with a step of degreasing, cleaning and acid-washing the surface of a brake shoe and then forming a chemical conversion coating thereon, a step of dipping the brake shoe having a chemical conversion coating formed thereon in a ceramics precursor solution to effect ceramics coating and a step of bonding a dried brake lining to the brake shoe under heating and pressure.

Abstract: A resin-impregnated porous filler having meso-pores, micro-pores, and macro-pores is obtained by inserting a coupling agent or an inorganic material between layers of a stratified clay mineral to prepare a crosslinked structure between the layers; making the stratified clay mineral three-dimensional; and impregnating the macro-pores with resin.

Abstract: Granules for a friction material is produced by: granulating a mixture including a friction modifying granular material and a resin binder in a fluidized bed under a presence of a liquid including a water-soluble or water-dispersible binder. The granules have a particle size of from 100 to 2000 ?m, an angle of repose of 40° or less, and a compression breakage strength of 10 MPa or less. The friction material is obtained by using the granules.

Abstract: A metal oxide composite particle is produced by hydrolyzing and condensing a hydrolysable metal compound in a solvent and in the presence of an inorganic particle and/or an organic particle to form a metal oxide sol, and subjecting the obtained sol to drying, heating and crushing processes.

Abstract: A friction member is manufactured by: a cleaning step of cleaning a pressure plate of a friction member; a shooting step of shooting a shot material having a predetermined particle diameter under a dry condition to a surface of the pressure plate; an adhesive application step of applying a powder adhesive on the surface of the pressure plate; and a forming treatment step of bonding a pre-formed product of a friction material to the surface of the pressure plate.

Abstract: The present invention provides a thermosetting resin composite material excellent in mechanical strength and wear resistance at high temperature, which is achieved by converting graphite into thin-layered one and dispersing it in a thermosetting resin homogeneously. A thermosetting resin composite material, wherein an organically modified graphite having an organic compound molecule inserted between graphite layers is mixed with a thermosetting resin, the organically modified graphite being prepared by subjecting graphite to a chemical treatment to form a graphite interlayer compound having a low-molecular substance inserted between graphite layers and subsequently immersing the resultant product in a solution of an organically modifying agent, as well as a process for producing the same. Preferably, the organically modified graphite is mixed with a thermosetting resin to be converted into thin-layered one having a layer thickness of 0.

Abstract: A work to be coated with multi layers of coating films, is provided with a first layer of coating film formed by coating a powder coating material of a thermosetting resin containing an electroconductive filler and an elastomer on a surface to be coated on the work; and a second layer of coating film formed by coating a powder coating material of a thermosetting resin containing water repellent particles on the first layer of coating film. The first layer of coating film and the second layer of coating film are baked by heating. It is preferable that the work is a friction member including a metal pressure plate and a friction material.
