Another method is to sinter powder (beads) of the same alloy material to form a porous layer. However, when the two alloys are sintered, the crystal grains become coarse and the fatigue strength decreases. It also has drawbacks such as inferior biocompatibility compared to titanium alloys. In addition, Ti-6Aj is a pad-shaped thing made of pressed pure titanium thin wire! There is a method of manufacturing a porous biomaterial that is fixed by diffusion bonding to the implant body made of -4V alloy, but pure titanium fine wire has weak strength, and in order to ensure 1 strength, Ti-6A1-4V wire is used. The disadvantage of thin wire is that it is very difficult to process the thin wire. There is also a manufacturing method in which Ti-6Al-4V alloy powder is fixed to the implant body made of the same metal material by sintering it at normal pressure, but this sintering temperature is 1200-1400℃.
Because the temperature must be as high as 00°C, crystal grains become coarser in the implant body, and furthermore, a needle-like structure is formed.
粒界の相の肥大化などの材質劣化が生じること等に短所
がある。更に、常圧焼結処理では接合強度に限界があり
、大粒径の粉末を強固に固着させることが困難である点
に短所がある。There are disadvantages such as material deterioration such as enlargement of grain boundary phases. Furthermore, the pressureless sintering process has the disadvantage that there is a limit to the bonding strength and that it is difficult to firmly fix large particle size powders.
チタン合金はβ−トランザス温度、即ち、β単相領域に

り。The temperature at which the titanium alloy reaches the β-transus temperature, that is, the β single-phase region, is Ti-6Aj! 1000° for -4V alloy
When heated to temperatures above around C, the crystal grains become coarser,
Although the ductility decreases due to the formation of an acicular structure, there is no substantial decrease in material strength when heated to a temperature below the β-transus temperature. Implant material with a complicated shape or a complicated porous layer. Preparation of implant materials is extremely difficult.

固に固着形成できるものである。The method of the present invention provides a metal member suitable for one artificial bone. That is, a titanium alloy is used as the implant material of the metal member, and a porous layer is provided on the surface of the titanium alloy, thereby providing a member that is convenient for bonding the bone and the implant material through bone tissue growth from the living bone.

。This cementless method is considered to be a very effective means of avoiding problems such as the negative effects of monomers on the human body, and it is thought that this cementless method will become the mainstream method for fixing artificial bones. In addition, Co-Cr alloys are currently widely used, but recently Ti-6Aj! -4
V-alloy is considered to be optimal as an implant material due to its biocompatibility, that is, its biocompatibility with 2 specific strength, that is, its lightness and strength, and its in vivo corrosion resistance, and it is thought that this material will be used more frequently in the future. . At present, titanium alloy implant materials with a porous layer made of titanium alloy powder sintered body and having appropriate porous bonding strength are not in practical use. This seems to be due to the fact that there is no way to firmly fix the layer to the implant body without deteriorating the material quality. 0 When used for artificial bone, the porous layer should have a pore size of 100 to 300 μm for fixation by bone tissue penetration. It is said that this is suitable, but if you want to obtain that pore size with powder, you have to use powder with a fairly large particle size, and if you bond powder with that particle size by pressureless sintering, you will not be able to achieve proper bonding. It was not possible to obtain strength.

ある。[Effects of the Invention] The following remarkable technical effects were obtained by the method of manufacturing a member having a porous layer according to the present invention. First, since the porous layers are bonded at a temperature that does not cause material deterioration, the problems of grain coarsening and acicular structure are resolved, and the porous layer is created without deterioration in material strength due to porous layer bonding. A method of manufacturing a metal member having a metal member is provided. Second, in order to bond the porous layers by applying an appropriate pressure, a metal member is provided that has a porous layer that has an appropriate pore size and is fixed with an appropriate bonding strength. Thirdly, since it uses HIP processing, it provides a manufacturing method that can form a porous layer on any complexly shaped surface at once, and can process and manufacture a large amount of products at one time. method provided. Fourthly, by performing 9 machining processes after fixing the porous layer to the in-brand body, we can
A method has been provided that allows products with complex porous layer shapes to be manufactured easily and at low cost. Accordingly, one object of the present invention is to provide a method by which an implant material having a highly reliable porous layer with a complicated shape can be manufactured in large quantities at low cost.
