Tantalum metal etc..
As shown in Figure 6 and Figure 7, to manufacture as a example by the femoral head prosthesis parts 10 of the hip prosthesis parts of the present embodiment
Method illustrates:
The manufacture method of femoral head prosthesis parts 10 in turn includes the following steps:
Prepare porous body, porous body include the first porous layer 11 and be formed at the first porous layer 11 side the
One porous matrix 131；
By cladding apparatus, tinsel fusing is formed the first metal on the surface of the first porous matrix 131 of porous body
Molten drop, the first metal drop penetrates into the hole of the first porous matrix 131 and merges formation first with the first porous matrix 131 and melts
Coating；
Continue through cladding apparatus on the surface of the first cladding layer and tinsel fusing is formed the second metal drop, the second gold medal
Belong to molten drop on the surface of the first cladding layer, successively pile up formation the first metal solid layer 12；
By the first metal solid layer 12 away from the first cladding layer surface by cutting, rubbing down be processed to form smooth surface；
Obtain prosthetic component.
It should be noted that porous body is an Integrate porous structure, the surface part of this loose structure forms first
Porous matrix 131, remainder forms the first porous layer 11.First metal drop and the second metal drop are that tinsel melts shape
The same metal become, the first metal that in the i.e. first cladding layer, the first metal drop is formed penetrates into structure and the first metal solid layer
12 are structure as a whole, and so ensure that the connection between the first cladding layer ultimately formed and the first metal solid layer 12 is strong
Degree.
