Patent ID: 8500966

Claim:
A process for making a nanolayered coated member, the process comprising the steps of: providing a substrate having a surface; providing a metal target; providing a metal aluminum target; rotating a substrate between the metal target and the metal aluminum target; supplying electrical power at a first metal target power level to the metal target wherein the first metal target power level is greater than zero; supplying electrical power at a first metal-aluminum target power level to the metal aluminum target wherein the first metal-aluminum target power level is greater than zero; depositing a coating comprising coating sets of alternating nanolayers; changing the deposition rate of the alternating nanolayers over a selected period of time during which electrical power supplied to the metal target changes from the first metal target power level to a second metal target power level wherein the second metal target power level is greater than zero and the electrical power supplied to the metal-aluminum target changes from the first metal-aluminum target power level to a second metal-aluminum target power level wherein the second metal-aluminum target power level is greater than zero; and controlling the deposition rate of the alternating nanolayers for a period of time after the electrical power supplied to the metal target reaches the second metal target power level and the electrical power supplied to the metal-aluminum target reaches the second metal-aluminum target power level.
