Compared to other types of brake pads, such as friction linings that use resin as a binding material, pads have higher heat resistance, a stable coefficient of friction, and excellent wear resistance, so they are used in various applications such as those used to tighten automobiles. Widely used in vehicles and other machinery. In most of these brake pads, the pressing is controlled by a piston or the like using hydraulic pressure such as brake fluid, and the brake pads are one-sided brake pads with a sintered metal friction material sintered only on one side of a metal plate called a core metal. In some cases, the back side of the metal plate is pushed directly with a hydraulic piston.

を見出し、本発明に到達した。(Problem to be Solved by the Invention) However, the sprayed layer provided on the surface of the metal plate on the piston side may wear out or crack and even peel off during repeated contact with the piston. There is room for improvement in terms of strength. As a result of intensive studies to solve the problem of improving the mechanical strength of brake bands, the present inventors have decided to provide a sprayed layer of heat-resistant heat insulating material such as ceramics between the metal plate and the sintered metal friction material layer. They have discovered that a brake pad with excellent mechanical strength can be obtained by using the method, and that such a brake pad can firmly bond the sintered metal friction material without adding any special measures such as plating the metal plate. The inventors have discovered that the present invention can be manufactured more easily than conventional products.

が、多くの利点から通常は鋼板が用いられる。The metal plate used in the present invention is not specified as any metal plate can be used as long as it does not cause deformation or damage when used as a brake pad, but there are many metal plates. Steel plates are usually used due to their advantages.

設ける必要はない。In the case of conventional brake bands made by bonding a sintered metal friction material directly onto a metal plate, the sinterability with the sintered metal friction material and the adhesive strength with the heat-resistant heat insulating material are improved. For this reason, it has been preferable to use a thin layer of copper, nickel, or an alloy thereof provided on the surface of the plate by a method such as plating, but in the case of the present invention, it is not necessary to provide such a thin layer. do not have.

原料粉を焼結するとよい。As the sintered metal friction material referred to in the present invention, any known sintered metal material conventionally used for brake pads can be used, but among them, at least one of copper or iron is the main component, and tin is used as the main component. , copper-based, iron-based, steel mixed-based, etc., with added ingredients such as zinc, lead, etc. are preferable, and in any case, graphite, graphite, or It is preferable to sinter raw material powder to which silica, mullite, etc. are added.
本発明ブレーキ・パッドを製造するには、前記金属板に
まず、前記耐熱性断熱材料を溶射する。To manufacture the brake pad of the present invention, the heat-resistant heat insulating material is first thermally sprayed onto the metal plate.
溶射の方法としてはプラズマ溶射、ガス火炎溶射その他
の方法のいずれでもよいが、溶射層と金属板との接着方
耽りみてプラズマ溶射法が最適である。The spraying method may be plasma spraying, gas flame spraying, or other methods, but the plasma spraying method is most suitable depending on the bonding method between the sprayed layer and the metal plate.

り好ましい。溶射は必ずしも金属板の全面に施す必要は
なく、その上に焼結金属摩擦材料Ｎを設ける部分にだけ
施せば充分で、溶射を施さない部分は適宜マスキングし
て溶射すればよい。The heat-resistant heat insulating material can be sprayed directly onto the metal plate, but it is also possible to spray a metal powder such as stainless steel, molybdenum, or nickel chrome on the surface of the metal plate in advance,
By forming the base layer, the heat insulating material is more firmly adhered to the metal plate. It is also preferable to spray the same metal powder as that used for the base layer on the upper surface of the layer formed by thermally spraying the heat insulating material, as this will improve the sinterability with the sintered metal friction material. Thermal spraying does not necessarily need to be applied to the entire surface of the metal plate; it is sufficient to apply the thermal spraying only to the portions on which the sintered metal friction material N is to be provided, and the portions that are not to be thermally sprayed may be appropriately masked and thermally sprayed.

The brake pad of the present invention can be easily produced by sintering in a reducing atmosphere while applying pressure.
