Abstract
The present invention relates to a method for manufacturing a diamond composite from diamond particles, comprising the steps of forming a work piece, heating the work piece and controlling the heating temperature and heating time so that a certain desired amount of graphite is created by graphitization of diamond particles, thereby creating an intermediate body, and infiltrating silicon or silicon alloy into the intermediate body. The invention also relates to a diamond composite produced by this method.
Claims44
A method for manufacturing a diamond composite, comprising:
- forming a work piece having a predetermined size and shape from a blend of 95-100 wt-% of diamond particles and 0-5 wt-% of a binder;
- heating the work piece at a pressure below 50 bar and a temperature below 1900° C. while controlling the temperature and heating time so that graphite is created from the diamond particles in an amount of 1-50 wt % of the amount of diamond particles, thereby creating an intermediate body;
- and
- infiltrating silicon or silicon alloy into the intermediate body, thereby creating a final body.
A method for manufacturing a diamond composite, comprising:
- forming a work piece having a predetermined size and shape from a blend of 95-100 wt % of diamond particles and 0-5 wt % of a binder;
- depositing carbon on the work piece by exposing the work piece to a gaseous hydrocarbon or gaseous hydrocarbons at a temperature sufficient to decompose the gaseous hydrocarbon or gaseous hydrocarbons;
- heating the work piece at a pressure below 50 bar and a temperature below 1900° C. while controlling the temperature and heating time so that graphite is created from the diamond particles in an amount of 1-50 wt % of the amount of diamond particles, thereby creating an intermediate body;
- and
- infiltrating silicon or silicon alloy into the intermediate body, thereby creating a final body.
