, Coating a film with extremely excellent lubricity such as Cu-3n-P alloy (phosphor bronze) on the surface of steel-based materials,
Accordingly, the present invention relates to a method suitable for manufacturing sliding parts that require seizure resistance and wear resistance under high surface pressure.

、プラズマ溶射などを挙げることかてきる。[Prior Art] Copper alloys such as bronze, habit metal, and phosphor bronze exhibit extremely excellent friction and wear characteristics under oil lubrication. When these are used as surface coatings on steel-based materials, coating methods include electrochemical plating, vapor deposition, sputtering, plasma spraying, and the like.

材か鉄鋼系材料の場合は、銅合金を直接コーティングし
ても密着力か小さく、剥れやすい、などの欠点かある。However, with these methods, - For boat fishing, the film formation speed is slow, the quality of the film deteriorates when the film thickness is increased, and the adhesion is insufficient even if the copper alloy is directly coated when the base material is steel-based. There are drawbacks such as being small and peeling easily.

ると同時にコストか嵩むという問題かある。In particular, coating by plasma spraying has a faster film formation speed than other coating methods, so it is applied to a wide range of areas, or it is used to directly coat copper or copper alloys on steel-based materials to form an alloy with it. Even if this is attempted, sufficient adhesion cannot be obtained and an undercoat of Ni or the like is required as an undercoat, resulting in the problem of an increase in the number of processing steps and an increase in cost.

しく、それを実現するための技術か望まれていた。In this way, conventional methods have been able to effectively and efficiently deposit a thick, dense copper alloy film with excellent lubricity on steel materials.
Moreover, it is difficult to create a coating with strong adhesion, and a technology to achieve this was desired.

である。[Means and effects for solving the problems] The coating method of the present invention for solving the above problems includes applying a laser to the surface of the steel material in a reduced pressure chamber when coating copper or copper alloy on the steel material. The coating is characterized by being coated by low-pressure laser spraying, in which copper or copper alloy powder is sprayed as a heat source.

動部品を製造するのに適している。Such a method of the present invention coats the surface of a steel-based material with a film of copper or a copper alloy such as bronze, habit metal, phosphor bronze, aluminum bronze, nickel bronze, or lead bronze with a high bonding strength. It is particularly suitable for manufacturing sliding parts that require good seizure resistance and wear resistance under high surface pressure.

くすることがてきる。The low-pressure laser spraying used in the present invention is a method of spraying copper or copper alloy powder in a low-pressure chamber using a laser as a heat source. Such low-pressure laser spraying makes it possible to form a dense coating. Furthermore, since the heat source is larger than that of a vacuum blaster or the like, a diffusion layer is likely to be formed at the boundary between the base material and the coating, and therefore the adhesion strength of the coating can be extremely increased.

For this reason, whether it is necessary to set optimal low-pressure laser thermal spraying conditions for various powders, or whether it is necessary to set optimal low-pressure laser thermal spraying conditions for various powders, we have found from previous experiments that low-pressure laser thermal spraying in the present invention has a relatively large influence mainly due to the following factors.
