... surface etching showed the diffusion of contaminates like Cu/Zn up to a depth of 25–30 µm. The wafer surface roughness in the middle section has always been observed to be poor due to short-circuiting and arcing within that zone. It reveals that wafer surface possesses wire marks due to intermittent...

... of PLA. Results showed that plasma treatment enhanced the PLA surface hydrophilicity. The overall surface roughness was also found to be increased. Moreover, both properties rose with increasing treatment time. Thus, according to the Wenzel’s relation, the surface roughening contributed...

.... The present work correlates the inter-relationships of various EDM machining parameters, namely, discharge current, pulse-on time, duty cycle, and gap voltage on the metal removal rate (MRR), electrode wear ratio (EWR), and surface roughness using the response surface methodology (RSM) while EDM of Al 2 O 3...

... the same and then become different with strain increase. It is shown that the strains in the two directions influence the profile. The relationship between the 3D surface roughness parameter (Sq) and strain appears to be linear, and a linear relation is also observed between surface area increment...

... was measured using a surface roughness measurement instrument to be about 1 – 2 μ m . The insulating electric resistance between the ion-sputtered film and the steel surface was measured after the preparation of the ion-sputtered film; its value was as high as several hundred ohms for an ion...

Zikry Microelectromechanical systems (MEMS), particularly those with radio frequency (rf) applications, have demonstrated significantly better performance over current electromechanical and solid-state technologies. Surface roughness and asperity microcontacts are critical...
