TIB2 ROD, AND METHOD OF FABRICATION AND USE

摘要

A TiB2 rod, and a method of fabrication therefore are is provided. It may be used to producing a TiB2 coating on the tip surfaces of a resistance spot welding (RSW) electrode, such as may be of a type for welding applications in automotive, and electronic industries. There may be a rod of material for coating the tips of welding rods that includes TiB2 ceramic having good electrical and thermal conductivities and a high melting temperature. The ne w TiB2 rod may be used to produce a TiB2 coating on an electrode tip surfaces by ESD, which ma y tend to be low in cost and which may tend to produce a higher electrode life as compared to an embodiment of TiC coating.
