Wetting of silicon carbide by copper alloys | SpringerLink

This work reports on a study of the wetting of SiC by some Copper alloys. The work is intended to gain a deeper understanding on the weeting behaviour of selected CuTi alloys in contact with a polycristalline silicon carbide substrate. Although the main body of this work deals with the CuTi/SiC system a few observations are also reported on the interaction between a CuZr alloy and a silicon
