In order to improve physical properties such as wear resistance, heat resistance, and corrosion resistance of a specific part of the surface of a metal member, a method of using heating means such as a laser, electron beam, or plasma arc to make the part highly alloyed. It has been known. For example, JP-A-57-
No. 155363 or Japanese Patent Application Laid-Open No. 158871/1987 discloses that a mixture of high-alloying metal powder and a binder is applied or adhered to the surface of a metal member to form a mixed substance, and this is then irradiated with laser, electron beam, etc. A method of forming an alloy layer by irradiating a beam is disclosed. However, in this method, when the binder is thermally decomposed by beam irradiation, the metal powder, binder, or binder decomposition products in the mixture layer are scattered, which not only reduces the yield of the alloyed layer but also causes the alloyed layer to deteriorate. This method has problems in terms of practicality, as it generates pinholes and cavities, and also contaminates the lens of the laser device.

Any metal or alloy powder commonly used for the application may be used.
It is not particularly limited. For example, for Cr supply, high carbon ferrochrome (Cr: 60 to 70

Fe: balance), high carbon ferromolybdenum (Mo: 55 to 65 wt%, C: 5 to 6 wt%, Si: 3 wt%, Fe: balance) for Mo supply, high carbon ferromolybdenum for B supply Ferroboron (B: 14-23% by weight,
C: 0.5 to 2.0% by weight, Si: 4% by weight or less, Fe: balance), Cu powder (preferably 1μ or less, more preferably 0.1μ or less ultrafine powder), Ni
For supply, ferronic acid (preferably 1μ
below, more preferably ultrafine powder of 0.1 μ or less), P
Ferrorin powder (P: 24% by weight,
Al: 1.1% by weight, balance of Fe), ferrosilicon powder for Si supply (Si: 80% by weight, C: 15% by weight,
Examples include P: 0.01% by weight, S: 0.01% by weight, Fe: balance). Powders of these metals or alloys may be used alone or as a mixture of two or more, depending on the purpose. The viscosity of this powder is generally 60 mesh or less.

量体との共重合体が好ましい。 The acrylic adhesive binder used in the present invention includes polymers and copolymers of acrylic esters and methacrylic esters, or polymerizable monomers having functional groups copolymerizable with these esters. Copolymers are preferred.

分となり好ましくない。 The appropriate blending ratio of the metal powder for high alloying and the acrylic adhesive binder is 90 to 99% by weight of the metal powder and 10 to 1% by weight of the adhesive binder. If the adhesive binder is less than 1% by weight, the adhesiveness will be insufficient and it will be difficult to attach it to the metal powder layer and the surface of the metal member, and if it is more than 10% by weight, the resin content will be excessive. This is not preferable because the bonding between the highly alloyed layer and the surface of the metal member becomes insufficient.

ー層として使用してもよい。 Various methods can be used to form a layer of a mixture of high alloying metal powder and acrylic adhesive binder on the surface of a metal member. For example, a liquid or paste obtained by adding an appropriate amount of a solvent such as acetone, toluene, methyl ethyl ketone, etc. to a mixture of high alloying metal powder and an acrylic adhesive binder and kneading the mixture is covered with release paper. After pouring it onto the formwork and evaporating the solvent, it is passed through rolling rolls to a suitable thickness, e.g. 0.5 to 5.0.
Form into a sheet with a thickness of mm. or,
Without using a solvent, a mixture of high-alloying metal powder and adhesive binder is kneaded with heating if necessary, and then formed into a sheet. After preheating the powder sheet created in this way, it is bonded by pressing onto the surface of a metal member. If necessary, an acrylic resin used as an adhesive binder may be applied to the surface of the metal member to form a temporary adhesive polymer layer to reinforce the adhesive force. Instead of coating, a sheet of adhesive binder may be used as the temporary adhesive polymer layer.

のばあいにも、タールピツチ状物質の生成量が少
なく、十分な一体性が得られない。 The temperature increase rate during the preheating treatment is preferably 40° C./min or less. If the speed is higher than 40° C./min, the low boiling point components in the adhesive binder will rapidly volatilize, which may damage the powder sheet layer and generate bubbles, which is not preferable. This preheating treatment may be carried out at 150°C to 380°C, preferably 200°C to 350°C, for 5 minutes or more. This preheating treatment causes a thermal decomposition polycondensation reaction to occur without completely burning out the synthetic resin used as the adhesive binder, producing a tar pit-like substance. This tar pitch material maintains the integrity of the powder sheet layer even at high temperatures. Therefore, the metal powder will not fall off or scatter due to impact, vibration, or heating during irradiation with a beam or the like. If the preheating temperature is lower than 150° C., the resin component will not be sufficiently thermally decomposed, resulting in a small amount of tar pitch-like material produced and insufficient integrity. On the other hand, if the preheating temperature is higher than 380° C., the resin component will rapidly decompose, and in this case as well, the amount of tar pitch-like material produced will be small and sufficient integrity will not be obtained.

要でありかつ不経済である。 If the preheating treatment time is shorter than 5 minutes, tar pitch-like substances are insufficiently produced and sufficient integrity cannot be obtained. Although the treatment time is appropriately determined depending on the heat treatment temperature, the type of resin component, etc., it is generally unnecessary and uneconomical to hold the treatment for 120 minutes or more.

きる。 After preheating in this manner, this powder sealing layer is adhered to the portion of the surface of the metal member to be highly alloyed, and local heating is performed using a high energy density heating means to highly alloy the metal member. Examples of the high energy density heating means used in the present invention include Japanese Patent Application Laid-open Nos. 158871-1987 and 155363-1983.

In the present invention, an acrylic resin is used as the resin binder, and this is preheated to form a tar pitch and then heat treated with a beam or the like, so that metal powder does not scatter due to rapid gasification of the resin. Therefore, the yield of metal powder is high.
