Coating Process for Non-Conductive Substrates and Devices Made From the Coating Process |
摘要 |
A method for manufacturing a surgical implant. A metal layer is deposited onto a polyaryletherketone (PAEK) substrate by generating a series of pulses using a high power impulse magnetron sputtering process. Each pulse is applied in a series of micro pulse steps comprising (i) micro pulse on steps ranging from 10 μs to 100 μs and (ii) micro pulse off steps ranging from 5 μs as to 400 μs; at a repetition frequency ranging from 50-2000 Hz with 2 micropulses to 20 micropulses per repetition, a total pulse on time ranging from 25 μs to 800 μs for 5 minutes to 300 minutes at averaged power ranging from 200 W to 3000 W. The series of pulses are performed in a unipolar mode or a bipolar mode. |

1. A method for manufacturing a surgical implant comprising the steps of:
depositing a metal layer onto a polyaryletherketone substrate by generating a series of bipolar pulses using a high power impulse magnetron sputtering process wherein the bipolar pulses are applied at a repetition frequency ranging from 50 Hz to 2000 Hz, total pulse on time ranging from 25 μs to 800 μs for 5 minutes to 300 minutes at averaged power ranging from 200 W to 3000 W. |
