<p>The invention provides a method of brazing a first body (10) to a second body (12) and has particular application to the bonding of a composite abrasive compact (10) to a substrate (12). The method involves the steps of providing a brazing shim (18) comprising at least two zones (30, 32) having differing melting temperatures, placing the shim (18) on a surface of the first body (12), placing a surface of the second body (10) on the shim (18) to form an unbonded assembly, applying heat to the assembly to cause the shim (18) to melt and allowing the assembly to cool to a temperature at which all the zones of the shim (18) become solid. <IMAGE></p> |
