A component of a mechanical apparatus, the component comprising:
- a cast body having an initial structure formed by a mold, and
- at least one feature deposited on the cast body using a solid state additive manufacturing process in which a melting temperature of a material of the at least one feature is not reached, wherein:
- the cast body has an outer surface and defines a groove in the outer surface;
- the groove has a surface area;
- at least a portion of the at least one feature is coupled to the surface area of the groove;
- and
- the cast body and the at least one feature deposited thereon form a complete structure of the component.
A method of preparing a component of a mechanical apparatus, the method comprising:
- preparing a cast body having an initial structure formed by a mold, and
- depositing at least one feature on the cast body using a solid state additive manufacturing process in which a melting temperature of a material of the at least one feature is not reached, wherein:
- the cast body has an outer surface and defines a groove in the outer surface;
- the groove has a surface area;
- at least a portion of the at least one feature is coupled to the surface area of the groove;
- and
- the cast body and the at least one feature deposited thereon form a complete structure of the component.
