ABSTRACT:
An invention is disclosed in which a mechanical hydraulic component includes fluid-bearing passageways. The fluid-bearing passageways are defined by a pre-formed tubing cluster which resides within a block which is cast around the tubing cluster in order to define a solid body which is fuse-bonded to the tubing cluster. The present mechanical body is formed by providing hollow tubing which is bent to provide a tube member having a desired configuration. A number of tube members are secured in order to provide a tubing cluster which defines the preformed fluid-bearing passageways. After that, a castable material is cast around the tubing cluster so as to produce a solid block with the tubing cluster embedded therein. The block and tubing cluster are formed of predetermined materials which result in chemical infiltration in order to produce a low-porosity fusion bond.
