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 &#x3bc;s to 100 &#x3bc;s and (ii) micro pulse off steps ranging from 5 &#x3bc;s as to 400 &#x3bc;s; 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 &#x3bc;s to 800 &#x3bc;s 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.

Coating process for non-conductive substrates and devices made from the coating process

A hard material layer system with a multilayer structure, comprising alternating layers A and B, with A layers having the composition MeONin atomic percent and B layers having the composition MeONin atomic percent, where the thermal conductivity of the A layers is greater than the thermal conductivity of the B layers. Meand Meeach comprise at least one metal of the group Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, and Al, pindicates the atomic percentage of Meand pindicates the atomic percentage of Meand the following is true: P=P, nindicates the oxygen concentration in the A layers in atomic percent and nindicates the oxygen concentration in the B layers in atomic percent and the following is true: n&#x3c;n, and mindicates the nitrogen concentration in the A layers in atomic percent and mindicates the nitrogen concentration in the B layers in atomic percent and the following is true: p/(n+m)=p/(n+m).
