In order to improve physical properties such as abrasion resistance, heat resistance, and corrosion resistance of a specific part of the surface of a metal member, heating means such as laser, electron beam, or Fi-glazma arc are used as a method of highly alloying the part. There are known ways to do this. For example, in JP-A-57-11383 or JP-A-171-171, a mixture layer consisting of a high alloying metal powder and a binder is applied or adhered to the surface of a metal material. A method is disclosed in which alloy H is formed by irradiating the alloy with a beam such as a laser or an electron beam. However, in this method, when the binder is thermally decomposed by beam irradiation, the metal powder in the mixture layer and the binder or binder decomposition products are scattered, which not only deteriorates the yield of the alloyed layer but also deteriorates the alloying layer. This method has the disadvantage of generating pinholes and cavities in the layer and contaminating the lens of the laser device, so this method is likely to have problems in terms of practicality.

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 used as a metal material coating "II". Alternatively, the above mixture may be formed into a sheet in advance and adhered to the desired area.Such sheets can be created by various methods.For example, The mixed wire liquid or mixed wire paste is poured onto a mold covered with a release paper, and after the solvent is evaporated, it is passed through a rolling roll to a suitable thickness, for example, O, !r~!;, Om. Form into a sheet. Alternatively, without using a solvent, knead a mixture of high alloying metal powder and adhesive binder while heating as necessary, and then form into a sheet. The powder sheet normally adheres easily by pressing it onto the surface of a metal component.However, if necessary, an acrylic resin used as an adhesive binder may be applied to the surface of the gold IfS component for temporary adhesion. The adhesive force may be reinforced by making the adhesive polymer JΔ equal to No. 1.

After a mixture layer of the high-alloying metal powder and the acrylic adhesive binder is thus formed on the surface of the metal member (hereinafter, the adhered mixture 1i will be referred to as a "powder sheet layer"), this is preheated. This preheating should be performed in a non-oxidizing atmosphere such as an inert gas such as nitrogen or argon, a reducing gas such as hydrogen, or a vacuum to prevent oxidation of the high alloying powder and adhesive binder. It is inevitable.

The heating rate is preferably 90°C for 7 minutes or less. l
If it is larger than /-0ocZ, the low boiling point component in the adhesive binder will rapidly volatilize, resulting in damage to the powder sheet layer, generation of air bubbles on the adhesive surface, and peeling of the powder sheet layer.

Iti, 200oC~3! It is sufficient to hold it for rO'c-'Ck minutes or more. Through this heat treatment, the synthetic resin used as the adhesive binder and temporary adhesion polymer undergoes a thermal decomposition polycondensation reaction without being completely burned out, producing a tar pitch-like substance. This tar pitch-like substance maintains the adhesion of the powder sheet layer even at high temperatures.

Therefore, the powder sheet layer does not peel off, fall off, scatter, or become misaligned due to impact, vibration, or heating during irradiation with the equal pressure beam. If the heat treatment source 1 is lower than /30"C, the thermal decomposition of the resin component will not be sufficient, and therefore the amount of tar pitch-like substances produced will be small, and sufficient adhesive strength will not be obtained. On the other hand, the heat treatment temperature If it is higher than 3g0oc, the resin component will rapidly decompose, and in this case, the amount of tar pitch-like substances produced will be small.

[Claims] (11. Form a layer of a mixture of metal or alloy powder containing a high alloying element and an acrylic adhesive binder on the surface of the metal member to be alloyed, and then is maintained at 750 to 3g00C for more than S minutes in a non-oxidizing atmosphere, and then the area to be highly alloyed is locally heated using a high energy density heating means to highly alloy the metal surface. High alloying method. (2) A sheet made by kneading and forming a metal or alloy powder containing a high alloying element and an acrylic adhesive binder at iso to 3g0oC in a non-oxidizing atmosphere. S
After being held for at least a minute, the metal is bonded to a portion of the surface of the metal member to be highly alloyed, and then the portion to be highly alloyed is locally heated with a high energy density heating means to be highly alloyed. Surface alloying method.
