Abstract
A manufacturing method includes the steps of providing a mould containing a matrix material, providing an infiltrant material arranged so that, when molten, the infiltrant material will infiltrate into the matrix material, and heating the matrix material and the infiltrant material by induction heating using an induction heater. The induction heater includes a first coil and a second coil, wherein the first and second coils are energised independently of one another to allow increased control over the heating of different parts of the matrix material and infiltrant material within the mould.
Claims29
A manufacturing method comprising the steps of:
- providing a mould containing a matrix material;
- providing an infiltrant material arranged so that, when molten, the infiltrant material will infiltrate into the matrix material;
- and
- heating the matrix material and the infiltrant material by induction heating using an induction heater;
- wherein the induction heater is operable to permit independent control over the heating of different parts of the matrix material and infiltrant material within the mould.
A manufacturing method comprising the steps of:
- providing a mould containing a matrix material;
- providing an infiltrant material arranged so that, when molten, the infiltrant material will infiltrate into the matrix material, the infiltrant material being located within a reservoir remote from the matrix material.
A manufacturing method comprising the steps of:
- providing a mould containing a blank and a matrix material;
- providing an infiltrant material arranged so that, when molten, the infiltrant material will infiltrate into the matrix material;
- and
- heating the matrix material and the infiltrant material by induction heating;
- wherein during the heating step the blank an end part of the blank is maintained at a level sufficiently low that the material of the blank can be used to form a pin.
