786号公報)かなされている。[Prior art] Aluminum is lighter and has better cooling properties than general materials such as steel, so it is widely used as a material for general mechanical parts and structural members, and is also used for cylinder heads and pistons in internal combustion engines. . However, in order to handle areas with severe thermal and mechanical loads, as well as to respond to the recent trend toward higher output and turbos, aluminum parts are required to have higher durability. Research on strengthening methods is underway. In cylinder heads and pistons that are directly exposed to combustion gas energy and heated to high temperatures, there is a particular need to improve thermal cracks that occur on the combustion surfaces. Thermal cracks occur intensively in areas where the cross section is small in response to thermal stress, that is, in areas where the wall thickness is thin. For example, thermal cracks in cylinder heads tend to occur in the partition between the intake and exhaust boats and between each of the intake and exhaust boats and the hot plug mounting hole or fuel injection nozzle mounting hole.
For pistons, local strengthening methods that tend to occur on the squish lip that borders the upper part of the cavity include:
Fe,
By remelting and alloying one or more of Ni, Co, ■, Zr, and Ce using high-density energy, specific parts of the aluminum alloy can be remelted and alloyed using high-density energy, without impairing the characteristics of aluminum alloy castings such as light weight and excellent thermal conductivity.

い。However, the proposed strengthening method involves directly remelting and alloying the heat-resistant metal into the aluminum base material, which is brittle (
There is a problem in that a large amount of metal open compounds with properties such as extremely low elongation) and hardness (reduced rigidity) are likely to be generated. A method of uniformly dispersing intermetallic compounds at the same time as alloying is also being researched, but it is technically difficult to control the amount of intermetallic compounds precipitated, but this method has not been put to practical use.

Since it is difficult to uniformly disperse AlxOs in the blending stage, there is a problem in that during remelting, AJ20m segregates in some areas, resulting in variations in crack resistance against heat shrinkage. In particular, the Vf value (volume ratio) of AjxOs
Even if it is desired to increase the Vf value, if the Vf value exceeds 30%, segregation will be too large and it can no longer be used.

ことができる。An oxide, nitride, or carbide such as SiC is coated with aluminum powder, and this coated powder is used as a sintering raw material. That is, in the present invention, the volume ratio of aluminum and reinforcing material is adjusted in the raw material stage before sintering, and a sintered material is obtained in which the reinforcing material is uniformly dispersed in the aluminum. Then, this sintered material is fused to the surface of the reinforced portion of the aluminum component without segregation to form a first layer. Furthermore, even if a second layer is formed on the surface of the first layer, the amount of intermetallic compounds generated will decrease due to an increase in the volume ratio of the reinforcing material, and the buffering effect of the first layer will be effectively used to reduce the heat generated during fusion welding. It is possible to prevent thermal cracks from occurring due to shrinkage.

ム(AC2B。In Fig. 1, 1 is an aluminum part such as a cylinder or a piston, and in order to locally strengthen the high-load parts or parts that receive mechanical load, the first step is to strengthen the specified reinforcement parts of the aluminum part 1. In the example, the sintered material 4 is placed on the recess 3 formed in the reinforced region 2 of the aluminum component 1! This is then remelted using high-density energy such as a laser, an electron beam, or TIG to form the first layer 5 in the recess 3 of the aluminum component. The sintered material 4 is formed by sintering capsule powder by current sintering or normal atmosphere sintering.
This is a sintering method in which at least one of the lower molds is provided movably in the pressing direction, xi having different polarities are attached to these molds, and sintering is performed by applying electricity. As shown in FIG. 3 or 4, the capsule powder is made of reinforcing material 7 that does not react with aluminum, such as AJ 20x, Six Ni,

As the stirrer, a stirrer is used that has rotary blades inside the housing and is configured to centrifugally transfer the capsule powder 10 along the inner surface of the housing (for example, a hybridization device, manufactured by Nara Kikai). That is, by centrifugally transferring the capsule powder 10 in the range of 1000 to 7000 rpm using a stirrer, moderate frictional heat is generated at the joint surface of the A j 203 powder 7a and the aluminum powder 9, and at the same time, the impact force , aluminum powder 9 is AJ

This sintered material 4 is filled into the recess 3 formed in the aluminum part 1 in advance, and fused by irradiating it with high-density energy to form a first layer 5 on the aluminum part 1.

As a second step, as shown in FIG. 2, heat-resistant metals 11 such as Co, Ni, Ti, Mo, and Zr are re-melted and built up on the first layer 5, either alone or in combination, to form a second layer. . Incidentally, the heat-resistant metal 11 is made of powder or solid material. This hot metal 11 is filled into the recess formed on the first layer 5, and re-melted overlay using high-density energy such as PTA (plasma tungsten arc), laser, electron beam, or TIG.

ミニウム部品1の熱亀裂を防止することが可能となる。By coating an oxide, nitride, or carbide such as SiC with aluminum powder 9 and using this coated powder as a sintering raw material, the Vf value of the reinforcing material 7 can be increased or decreased more freely than before.
By setting the vf value of the first layer 5 to 30% or more, it is possible to reduce the amount of metal compounds generated at the interface between the first layer 5 and the second layer 12, and this sintered material 4 is remelted with a high-density energy beam. By forming the first layer 5 in this manner, a stable first layer 5 in which the reinforcing material 7 is dispersed without segregation in aluminum can be formed. Therefore, it is possible to effectively utilize the buffering effect of the first layer 5 against the second layer 12 to prevent thermal cracking of the reinforced portion 2, thereby preventing thermal cracking of the aluminum component 1.
