Abstract:
1. A method for applying a coating by cathodic arc coater, comprising the steps of: providing a cathodic arc coater that includes a power source and utilizes a disk shaped cathode, providing a first disk shaped cathode having an evaporative surface extending axially between a first end surface and a second end surface, and the evaporative surface having a first surface area in said coater; determining a maximum acceptable power density for the evaporative surface of said first disk shaped cathode; and increasing a deposition rate of a material liberated from said cathode forming said coating; said deposition increasing step comprising replacing said first disk shaped cathode with a second disk shaped cathode having an evaporative surface with a second surface area greater than said first surface area and increasing current amperage applied to said second disk shaped cathode while maintaining power density equal to or less than said maximum acceptable power density.
