Abstract
The present invention provides a method for making a superabrasive composite material having the general formula SixCyNz, and tools containing such a material. In one aspect, vapor forms of Si, C, and N elements are deposited onto a molten metal catalyst and solid SixCyNz is precipitated therefrom.
Claims37
A method of making a superabrasive composite material having the general formula SixCyNz, comprising the steps of:
- a) depositing a particulate form of Si and a metal containing catalyst on a substrate;
- b) heating the substrate to a temperature sufficient to melt the metal containing catalyst;
- and
- c) depositing C, and N elements in a vapor form onto the molten metal containing catalyst in an amount sufficient to bond with the Si and produce a composite SixCyNz material in the form of grits.
