... technology, and the quality of samples was optimized by the Box–Behnken surface response method. Taking the surface roughness Sa as the response value, a regression analysis of four parameters of selective laser melting (laser power, scanning speed, scanning spacing, and scanning strategy) was designed using...

... 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. References [1] Möller , H. J. , 2006 , “ Wafering of Silicon...

... 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...

... of the coating agent is polyvinyl resin. The insulating film was made by wiping the steel surface with absorbent cotton wetted by the coating agent. The thickness of the insulating film was measured using a surface roughness measurement instrument to be about 1 – 2 μ m . The insulating electric...
