The effect of surface roughness on direct wafer

A theory is presented which describes the initial direct wafer bonding process. The effect of surface microroughness on the bondability is studied on the basis of the theory of contact and adhesion of elastic solids. An effective bonding energy, the maximum of which is the specific surface energy of adhesion, is proposed to describe the real binding energy of the bonding interface, including

Effect of Process Parameters on the Generated Surface

The aim of this work is to investigate the effect of varying process parameters on the resultant roughness of the down-facing surfaces in selective laser melting (SLM). A systematic experimental study was carried out and the effects of the interaction of the different parameters and their effect on the surface roughness (Sa) were analyzed. It Effect of Process Parameters on the Surface Roughness of Jan 01, 2016 · In order to optimize surface roughness in these structures, samples covering a range of overhang angles and process parameters were built in a laser powder bed fusion system. Analysis of the surface roughness was then performed to determine a relationship between process parameters, angle of the overhanging surface, and surface roughness.

Effect of process parameters and electropolishing on the May 01, 2019 · A two-level 2 51 fractional factorial design of experiments was employed to study the relationship between five L-PBF process parameters and the surface roughness of interior channels in as-fabricated NiTi. The process parameters are listed in Table 1 and include:laser power [W], scan speed [mm/s], hatch space [m], scan pattern [an alternating x-axis scan with 45°/+45° or 0°/90

Effect of process parameters on surface roughness of

Mar 03, 2016 · The surface roughness (R a) was measured on all the castings for flat surface A as shown in Fig. 1.Mitotoyo Surf Test SJ201 was used to measure the surface roughness as per ISO 1997 standard. The signal to noise (S/N) ratio was calculated for each surface roughness value.The S/N ratio is used to determine the influence and variation caused by each factor. Experimental Investigation of Effect of Process material removal rate and surface roughness are investigated, also optimum process parameters are studied. An L 8 orthogonal array (mixed level design), analysis of variance (ANOVA) and the signal to-noise (S/N) ratio are used in this study. Mixed levels of machining parameters are used and experiments are done on conventional lathe machine.
