     A modified Electro-Spark Deposition (ESD) process is used to produce drilling equipment.  Utilizing improved process control, automation, multiple heads, novel electrodes chemistries and multilayer coatings yields superior products.

     Novel ESD process enhances slip inserts and tong dies for pipe handling that support greater loads while causing less damage to both carbon and alloy steel tubing than current tooling for pipe handling.  Improved ESD coatings are utilized on wear bands for drill pipe.  The Spring Band was designed to avoid metallurgical problems on aluminum pipe and to eliminate damage to carbon and alloy steel drill pipe caused by welded wear bands.

     Improvements to the ESD process will be outlined.  A discussion of coatings for pipe handling tools will be provided along with experimental data that demonstrates its superior performance.  Spring Bands used to solve problems encountered with welded wear bands on aluminum and steel drill pipe will be highlighted.
